Every mattress needs a base. No mattress is complete without one. Especially when we’re talking about an elite level sleep service like the incredible Purple mattress. If you’re going to invest in a mattress like the Purple, then you’re going to want to make sure that it has a base that is worthy of the mattress and will provide the support that you need. If you’re going to get a base for the Purple mattress, then it may as well be a box spring.

A box spring serves a few different purposes for the Purple mattress. First off, It gets your mattress off the floor, which makes it easier for you to get in and out of bed. This is important. Next up, it provides support for your mattress and finally, it promotes airflow (which helps keep pesky mold and mildew away). Obviously, a box spring plays a pretty important role in maximizing the potential of any Purple mattress. So, only one important question remains: how do you know which one is best for your Purple mattress?

You have plenty of choices available when it comes to box springs, so you’re going to have to do a little homework to make sure you buy the right one for your mattress, for yourself, and for your bedroom.  Thankfully you’ve come to the right place. Here at the Sleep Judge, we’ve tried almost all of the box springs out there. The good ones, the bad ones, and the ugly ones. Our sleep experts know what you need and by the end of this guide, you should have a good idea of which is the best box spring for your Purple mattress. So keep your eyes glued to this page and scroll away. All will be revealed.

Does the Purple Mattress Need a Box Spring?

If you recall the traditional innerspring mattresses from yesteryear, you’ll remember that they all came with box springs. The fabric-covered wooden frame had springs to match your mattresses springs This was  meant to help support, sort of like the sleep equivalent of shock absorbers. These old box springs don’t really exist anymore. I mean, they do, but good luck finding one! Times have changed and so have box springs. Today’s box springs have no springs (sorry to ruin that illusion for you). Instead, they’re like big boxes of wooden or metal support beams and slats with a flat top to support all the new memory foam and latex beds that everyone’s buying now. You don’t need those big springs anymore. Support comes in new forms now.

The Purple mattress isn’t an innerspring mattress, but it also isn’t memory foam or latex. It’s probably closest to foam, though. Any mattress that’s made of foam or latex need the proper support to ensure you’re getting the right support from the mattress. Purple’s secret blend of materials is both supportive and flexible. Because of that flexibility, though, it needs a flat, supportive base to rest on – or at least one that’s strong and won’t allow the mattress to sort of seep through openings.

So, you could use a platform bed that has wooden or metal slats built in, but sometimes these can present a problem. Any foam-based mattress could slip through the slats and be damaged over time. That would defeat the purpose of the support that you’re hoping to provide, now wouldn’t it? Plus, if part of your mattress dips below what’s supposed to be supporting it, well, it’s not doing its job by supporting you, is it?

The Purple mattress could be tossed on the floor and used there with almost no issue – after all, the floor is a flat, supportive surface. However, after many nights of use, the moisture that’s meant to flow through your mattress and away from your bed is likely to just get trapped underneath and could create an environment ideal for mold and mildew.

Your best bet is to buy a box spring to work with your new Purple mattress, which helps you get the best out of your mattress.

What is the Purple Mattress, Anyway?

Well, chances are that It’s not like any mattress you’ve seen so far. It doesn’t rely on astronaut technology to sell it, and the Purple mattress slingers aren’t interested in selling you on how latex is better. Instead, the manufacturer came up with its own mix of polymer and foam with a process to create a new kind of bed. It looks like a big purple grid, and it’s that design that helps create the airflow needed to keep you cool as you sleep.

If you were to peel the top grid-like layer off the Purple mattress, you’d find two more layers of bed underneath. These lower level layers are made of polyurethane foam. They vary in densities and form the base support your spine and pressure points need. It’s these two layers that give you the firmness you need to stay aligned whether you’re sleeping on your back, side, or face.

These three layers work together to give you a mattress that’s firm for support and soft for comfort. The best of both worlds. One of the things to consider is how much weight a mattress can hold, and whether it feels different for those who are lighter-weight or heavier. If you’re smaller in frame and hoping this bed won’t be too firm, no worries – it should feel like you’re sleeping on a cloud. The weight limit is 600 pounds total, so even if you’re overweight, the Purple mattress should be a comfortable bed. This is truly a bed for everyone.

Types of Box Springs

The makers of the Purple mattress make it clear that there is only one type of foundation that is off-limits for your bed: an actual box spring. This means you have a lot of options, but a traditional box spring with springs is out.

Adjustable Base

Good news! Yep, you can use one of these. The most important aspect of a foundation for your Purple mattress is that it have a flat, firm, solid surface. Your Purple mattress is flexible enough to bend with an adjustable bed frame, so this is a go. Is it the best box spring option? That’s really a matter of opinion, and it depends on what your health needs are.

Platform Base

Sure, this works. Purple even makes its own base that eliminates the need for a bed frame. The big selling point of using a platform base is that it’s a sturdy box spring alternative that can hold thousands of pounds, so you won’t have to do much math to figure out whether it can support your mattress and you and your sleeping partner.

Box Springs (Metal)

These look similar to traditional box springs because they’re usually covered with fabric. The guts of these bases are usually made up of a metal box frame with support beams that run the center from top to bottom and side to side. There are metal slats that run the length of the bed, and it’s this part you need to pay attention to – make sure slats are no more than 4 inches apart.

Box Springs (Wooden)

Like the metal box springs of today, the wooden ones are built the same, but just out of wood instead. Also, these don’t have springs like those of the past. And that’s a good thing too, so make sure they don’t, or you could void your Purple mattress warranty. Like the metal ones, look into the slat spacing, or you may need to add a Bunkie board.

Bunkie Board

A Bunkie board is a good option if you don’t want to add height to your bed, but it’s also a good supplemental piece. It’s essentially a thin platform base that’s no more than 2 inches high. Some are made of solid plywood, while others are made of minimally-spaced slats, so you can still get that air flow that the Purple Mattress needs to thrive. If you have a platform bed or base that has slats that are too thin or spaced too far apart, but you want to use it, just slap one of these on top and you should get the support you need.

Best Box Spring for Purple: The Reviews

1. The Purple Mattress Platform Base

SPECS

  • Type: Metal platform base
  • Sizes: Twin XL, Queen, King, California King
  • Weight: Queen – 44 lbs.
  • Dimensions: Queen – 59.5 x 79.5 x 16.5″
  • Material: Steel
  • Warranty: Lifetime

As mentioned above, Purple offers a platform base to serve as both a boxspring and bed frame alternative. Naturally, this would be a good choice for your Purple mattress because it’s from the same people, but why does it work well? You get more support from this foundation than others because of the way it’s made and what it’s made of. In fact, it can handle about 4,600 pounds without giving. The support slats are made of metal, and they crisscross, which means you get that flat surface you need for the support, but it still has air flow.

You’re also guaranteed no bed bugs are going to cozy up to your foundation because it’s made completely of steel. This platform base is more than 16 inches high, so you also get all kinds of storage space underneath your bed – something that you aren’t likely to get with a platform bed or a typical box spring. If you’re concerned about the look of your bed, you can use the included headboard attachments so you can add something pretty. The base may feel a bit unsteady and move a bit, or your mattress could feel as though it slides on the foundation.

Pros

  • Quiet
  • Allows for storage under your bed
  • Easy to carry
  • Sturdy
  • Lifetime warranty

Cons

  • You can’t return it
  • No bounce
  • May feel unsteady

If you want extra-sturdy support, the Purple platform base holds thousands of pounds, and it’s tall to give you storage under your bed.

2. Zinus 9-Inch High Profile Smart Box Spring

OVERVIEW

  • Type: Metal box base
  • Sizes: Twin, Twin XL, Full, Queen, King, California King
  • Weight: Queen – 42 lbs.
  • Dimensions: Queen – 59.7 x 78.9 x 9″
  • Material: Steel, fabric
  • Warranty: 5 years

When you want the luxury that comes with a tall bed, then you might want to consider the 9-inch high Zinus High Profile Smart box spring. Place this fabric-covered steel frame on a bed frame and your Purple mattress on top and you’ll have a bedroom centerpiece. It’s an affordable box spring that gives you support and airflow to let your Purple mattress shine.

You can probably assemble this bed foundation in minutes, and it doesn’t require you to fish out tools from your toolbox – they’re all included in the box. The slats in this foundation are farther apart than you’d want for your Purple mattress, though. At 8 inches apart, you may need to add a Bunkie board. That’s too much of a gap and you run the risk of damaging your mattress over time without the extra support.

Pros

  • No squeaking
  • Allows air to flow
  • Easy to assemble
  • Sturdy

Cons

  • Slats are far apart

This affordable, tall steel box spring is a good choice for most mattresses, including your Purple mattress, but you may need to add a Bunkie board for more support.

3. CPS Wood Products Premium Easy Fit Box Spring Foundation

SPECS

  • Type: Box base
  • Sizes: Twin XL, Full, Queen, King, California King
  • Weight: Queen – 59.5 lbs.
  • Dimensions: Queen – 79 x 60 x 8″
  • Material: Wood, fabric
  • Warranty: N/A

A wooden box spring foundation like the CPS Wood Products premium solution is a good choice for any mattress, including the Purple mattress. Regardless of which size you choose, the foundation is made the same way: A center support beam runs the length of the foundation, and it’s topped with wooden slats held together with side straps.

The bed is made completely of spruce that’s responsibly sourced, so it’s an eco-friendly purchase, too. And that spruce is solid, sturdy, and all natural. The slats are spaced about 4 inches apart and then covered with a fabric sleeve. This make it a good choice for your Purple mattress because it offers the support you and your mattress need, plus airflow to keep things clean and cool. That’s all of the essentials taken care of, allowing you to rest easy ontop of this boxspring.

Pros

  • Doesn’t squeak
  • Breathable
  • Sturdy

Cons

  • Pricier option

If you want an eco-conscious wooden foundation for your Purple mattress, this could be the best choice for you.

 

4. Classic Brands Instant Foundation Low Profile 4-Inch Box Spring

SPECS

  • Type: Box base
  • Sizes: Twin, Twin XL, Full, Full XL, Queen, King, California King
  • Weight: Queen – 53.5 lbs.
  • Dimensions: Queen – 79 x 59.5 x 4″
  • Material: Wood, cotton blend
  • Warranty: 3 years

Not everyone wants a tall bed to climb into, which is why you may want to pick this Classic Brands 4-inch high box spring. It’s a little taller than a Bunkie board, and offers a supportive surface for your Purple mattress. This foundation will work well on its own on a bed frame, or place inside a platform bed, without adding too much height.

The slats are a little farther apart than you may want at about 4.5 inches, so you may want to modify this foundation to add another slat or two to close those gaps. Another option is to add a Bunkie board on top, which should only raise everything by 2 more inches. It’s one of the more affordable wooden options, so it may be the best pick for you. If there’s anything you want to watch out with this foundation, it’s rough edges and potential squeaks. Use a bit of sandpaper on the corners and add some wood glue to the screws and holes when you put it together.

Pros

  • Good warranty
  • Strong, sturdy
  • Affordable

Cons

  • Slats are 4.5 inches apart
  • May squeak without modifications
  • Assembly takes a while

If you’re looking for a solid wood foundation that’s also affordable, this could be the best box spring for your Purple mattress.

5. Zinus 8 Inch Profile Wood Box Spring

SPECS

  • Type: Box base
  • Sizes: Twin, Full, Queen, King
  • Weight: Queen – 48 lbs.
  • Dimensions: Queen – 79.5 x 59.5 x 8″
  • Material: Wood, fabric
  • Warranty: 5 years

A wooden box spring like this one from Zinus provides the strong support a Purple mattress needs. The slats are spaced well so that you get air flowing from your mattress through your foundation, rather than getting trapped (like it would if you put your mattress on the floor). Plus, this is a tall foundation, so it gives your mattress an 8-inch boost up from the bed frame.

Perhaps the biggest issue with this foundation is its weight limit. It’s only rated for 500 pounds, and that includes however much your mattress weighs. So, this may be a better option for those who are lighter weight and smaller in frame than others. You could modify your foundation to include more support beams and legs to hold more weight, but that might not be worth the effort for you.

Pros

  • Easy to assemble
  • Strong support
  • Good warranty

Cons

  • Not available in all sizes

A foundation that’s tall, made of wood, affordable, and has perfectly-spaces slats seems like it was made for the Purple mattress, and it could be what you’re looking for.

6. Spinal Solution 8-Inch Queen Size Fully Assembled Split Foundation Box Spring

SPECS

  • Type: Box base
  • Sizes: Queen
  • Weight: Queen – 50 lbs.
  • Dimensions: Queen – 79.5 x 60 x 8″
  • Material: Wood, fabric
  • Warranty: N/A

It can be difficult to find a split foundation in sizes other than King (a King-sized bed is really just like two Twin-sized beds), but Spinal Solution offers one in the most popular bed size: Queen. A split box spring is much easier to move from one room to another. It also offers support on each side of the bed for two sleepers with that all-important center support beam.

A big benefit of this Spinal Solution box spring is that it’s fully assembled, so you won’t have to do it yourself. Of course, that contributes to the higher price of this foundation, but that could be worth it for you. The wooden slats are sturdy, but they’re spaced about 7 inches apart. That’s a bit too far for the Purple mattress. There is a piece of strong cardboard that lays on top of the foundation, which might be enough support, but you could be better off adding a Bunkie board to this bed.

Pros

  • Fully assembled
  • Sturdy
  • Split design

Cons

  • An expensive option
  • Not available in other sizes

Your Purple mattress might work well on this split designed foundation, but only if you choose the Queen size.

7. Lifetime Sleep Products 4″ Low Profile Box Spring

SPECS

  • Type: Box base
  • Sizes: Twin, Twin XL, Full, Queen, King
  • Weight: Queen – 50 lbs.
  • Dimensions: Queen – 80 x 60 x 4″
  • Material: Wood, fabric
  • Warranty: Lifetime

A low-profile box spring can be necessary for some sleepers who may have a hard time crawling in or out of a tall bed, and Lifetime Sleep Products answers that need with its 4-inch tall foundation. The Purple mattress requires a strong, supportive surface, and this box spring may be good for it. The slats are spaced farther apart than you’d probably like, but it should work.

Assembly of this box spring is super easy, and you’ll probably be able to do it single-handedly in less than an hour. You might want to make your life easier by grabbing an electric screwdriver or drill because you’ll have about 40 screws to secure everything. Some users added their own slats when assembling this piece to close the 4-or-so-inch gaps between the slats. This isn’t as worrying of a gap between slats as some of the other options, but it’s still enough that it could damage your mattress over time.

Pros

  • Supportive
  • Easy to assemble
  • Doesn’t squeak
  • Lifetime warranty

Cons

  • Not available for Cal. King

If you’re looking for a low-profile wooden box spring, this could be a great choice for your Purple mattress – but you may want to add a few more slats for more support.

 

8. Best Price Mattress New Innovated Box Spring

SPECS

  • Type: Metal foundation
  • Sizes: Twin, Twin XL, Full, Queen, King, California King
  • Weight: Queen – 37 lbs.
  • Dimensions: Queen – 80 x 60 x 14″
  • Material: Steel
  • Warranty: 5 years

This Best Price Mattress box spring looks familiar if you checked out the Purple foundation. It’s not quite as tall as the Purple option, but it’s built similarly and still offers more storage for under your bed than most beds. Assembling it is as easy as unfolding it, securing the two lengths together, and hand-tightening some wing nuts.

The steel frame doesn’t require you to have a bed frame, and it has plenty of legs to offer support from the top to the bottom of your bed. The biggest differences between this frame and the Purple foundation are the height and there are no headboard attachments. There are plenty of slats vertically and horizontally to support your Purple mattress. No need to worry about extra support. This frame has you and your Purple mattress covered.

Pros

  • Supportive
  • Affordable
  • Allows storage under bed
  • No-tool assembly

Cons

  • No fabric cover

If you need a strong, easy-to-assemble, and affordable steel foundation for your Purple mattress, this could be your best option.

Conclusion

The best thing about the changes in mattresses and foundations today is that you have so many options. You can find the one that works best for you, whether it’s tall and luxurious, low-profile for easy access, made of steel and extremely sturdy, or made of eco-friendly wood. All of them are strong, provide good air flow, and work well for your new Purple mattress. There is such a wide variety of foundations available these days that you have the space to consider personal preference while still comfortably knowing that your Purple mattress will be fully supported regardless of which direction you choose to lean.

Choosing the best one comes down to picking the one that’s built to perfectly support your Purple mattress. The Zinus 80-Inch Profile Wood Box Spring includes perfectly-spaced slats so your Purple mattress doesn’t start to sink in between bars, but they are spaced so that heat and moisture circulate well. Although this one is 8 inches high, you can find the same box spring at 4 inches high. It’s an affordable and attractive choice for your bedroom and your Purple mattress.

So, that’s our preferred option. However, if it doesn’t work for you, then any other the other options listed above should work just as well. This is going to be your bed after all. The final decision ultimately comes down to you. However, now you are armed with the knowledge of what your Purple mattress needs and how many different foundations fall within those requirements. So, what are you waiting for?! Go forth and construct the bed that you deserve.
