You’ve recently decided that you want to update your bedroom and you started by buying a platform bed. Whether it’s traditional, modern, romantic, or contemporary in design, you probably noticed that it came with a flat wooden panel or slats at the bottom. Now you have questions. Will your old mattress and box spring work, or do you need to buy a new mattress? What about those slats – will they work for a memory foam mattress? All of these questions are answered below in this guide to help you find the best mattress for platform beds.

What is a Platform Bed?

Strictly speaking, a platform bed is simply a frame that acts as a foundation for a mattress. You don’t need a box spring, but if you prefer a taller bed, feel free to use a box spring. The foundation that a platform bed provides with slats, which are usually made of wood or metal, is enough as is. A box spring won’t make your bed more or less comfortable than the platform bed alone.

You can find a variety of styles at a variety of prices. From a simple metal frame to ornately carved wooden monstrosities that make bold statements in your bedroom, you can find a design that works for you and your décor.

How Much Weight Can a Platform Bed Hold?

There is no definitive answer to this question. A platform bed could hold only as little as 450 lbs. or as much as 4,400 lbs. It really depends on the platform bed you buy and its weight capacity. Generally speaking, if you’re overweight and concerned about sturdiness, look into buying a platform bed with a flat foundation. You can also buy a separate platform to place on a standard platform bed with slats.

When you’re assessing the weight capacity of a platform bed, be sure to include the weight of your mattress, yourself, your partner, any children that join you in bed, and pets. Individual slats can easily bend and break under extreme pressure, so keep this in mind if you kneel or stand on your bed. The good news is, slats are easy to replace, so you won’t have to replace the entire bed.

Best Type of Mattress for Platform Beds

You may be surprised to find out that any mattress works with a platform bed. It’s true! There are a few things to keep in mind with each mattress, though.

Innerspring Mattress

Your traditional innerspring mattress can be given an update by simply slipping it into a platform bed. Leave the box spring out to give you a low-profile, sleek look, or include the box spring for a taller bed. The only time you may not want to use this type of mattress on a platform bed is when your mattress warranty requires you to use a box spring and you don’t want a super tall bed.

memory foam mattress

Memory Foam Mattress

Foam mattresses are one of the most versatile beds out there. You can usually toss these mattresses on the floor, a box spring, a platform bed, or whatever you’d like. Memory foam does benefit from being on a platform bed with slats that are evenly spaced and no more than 3″ apart. The slats offer support, but also some breathability that foam needs. However, you should be sure the spacing is close because the wider apart the slats, the more likely the foam mattress will sink into those spaces, which can throw off the shape and support of the mattress.

Latex Mattress

If you prefer to sleep on an all-latex mattress, then you’re going to need a strong foundation. Latex mattresses are usually much heavier than traditional innerspring or memory foam mattresses. A platform bed is a suitable option, as long as it’s rated to hold the weight of your mattress and you (and your partner, pets, and children … and laundry?). Just like foam mattresses, slats are more than fine, as long as they’re spaced close together – 3″ to 4″ is about right. Any wider than that and you may find that your latex mattress sags in the gaps.

What About Adjustable Beds?

The answer to this question depends on who you ask. Most platform beds are not big enough to accommodate an adjustable bed, and the adjustable frame may be hindered by the platform structure. Some will work, but usually those who prefer adjustable bed just use that as the foundation for their mattress. Read the manufacturer’s labels carefully to make sure you don’t waste money on a bed that won’t work with an adjustable frame.

Platform Bed Mattress Reviews

Innerspring

Helix Sleep Mattress

Specs

  • Weight: <100 lbs.
  • Size: 60x80x10 in.
  • Warranty: 5 years
  • Type: Foam, Gel, Innerspring
  • Firmness: Custom

Good luck finding an innerspring mattress that’s OK to use on a platform bed and still retain your warranty. Helix Sleep combines foam, gel, and encased coils for a hybrid mattress in an attempt to please everyone. The benefit of the microcoils is that it provides the bounce you may want out of a bed. The gel layer is added for springy support, as well. And there’s a layer of foam, which is meant to add the firm feel you need to sleep soundly, and for motion isolation.

This mattress works well on a box spring or a platform bed, thanks to the combination of materials. One of the features this Helix offers that many foam and latex mattresses don’t is almost complete customizability. From the feel to the support, you get your choice. You simply answer a few questions and the company picks out the layers that you need for your best night’s sleep.

You shouldn’t run into issues such as too firm or too soft because the mattress is custom-made for how you sleep – and how your partner sleeps. The weight of each mattress varies based on the materials used, but none are more than 100 pounds, which makes this a good choice for a platform bed.

R

Pros

  • Customizable
  • Breathable for cooler sleep
  • Encased coils for bounce, support
  • Hybrid ensures comfort, support
Q

Cons

  • 600-lb. weight limit
  • Short warranty

It’s possible that this is the best type of mattress for a platform bed because it combines three different materials to give you comfort, support, and softness, but doesn’t require a box spring.

Memory Foam

Zinus Sleep 12-Inch Pressure Relief Mattress

Specs

  • Warranty: 10 years
  • Type: Memory foam
  • Firmness: Firm

Although memory foam mattresses used to be considered a luxury option, they’ve become much more affordable in recent years. This Zinus pressure relief mattress combines three layers of foam in different densities to provide you the support you need and the comfort you want.

There’s twelve whole inches of luxurious support; 3” of memory foam, 3” of pressure relieving comfort foam, and then 6” of high density support base foam. Like any memory foam mattress, it squishes under your weight, and conforms to your body. This property of foam is great for keeping you cradled as you sleep, but it you may find that you sweat more at night.

Memory foam isn’t as breathable as other materials for mattresses, which is why this is a good mattress choice for a platform bed with slats. The slats underneath your bed help as a foundation, but also with the airflow that you mattress requires. There’s little to no edge support, so it may not seem as stable as other beds.

R

Pros

  • Most affordable option
  • Easily fits in platform beds
  • Very firm – suitable for back or side sleepers
  • Conforms to your body for added comfort
Q

Cons

  • May not be great for stomach sleepers
  • Strong chemical smell
  • Weak edge support
This could be the best budget memory foam mattress for a platform bed if you choose a low-profile frame that can’t handle a thick, heavy mattress.

Amerisleep Liberty Natural Memory Foam Mattress

Specs

  • Warranty: 10 years
  • Type: Memory foam
  • Firmness: Medium

It can be difficult to pull the trigger on buying a 100% memory foam mattress for those who are used to innerspring mattresses. Amerisleep’s Liberty stacks layers of different memory foam types for a more comfortable feel, especially for those who sleep on their sides. However, it’s a versatile mattress – because of those layers, you get the support you need and the comfort you crave. Regardless of whether you sleep on your back, stomach, side, or some other position not yet labeled, it’s a medium level of comfort, so great for all.

As with almost any memory foam mattress, you can slide this into any platform bed. Use slats to help promote air flow, which keeps the mattress from retaining too much heat. Thankfully, there is a gel-infused memory foam layer that helps keep you cool, though. The 12-inch height of this bed gives you that luxurious plush feel that’s so common in hotel rooms.

It’s a standard queen-sized mattress, so your current sheets should fit just fine. It’s a bit heavier than some memory foam mattresses, but it’s less than 100 pounds, so it won’t eat up too much of the weight capacity of your platform bed. The biggest issue you may have with this bed is that it has very little edge support.

R

Pros

  • Affordable
  • Layers of foam for support, comfort
  • Relieves pressure points
  • Good for all sleep positions
Q

Cons

  • May not be as firm as you’d expect
  • No edge support
Amerisleep gets top ratings for its mattresses, and the Liberty offers more comfort and support than you might expect in a memory foam mattress – it’s a good choice for all sleepers, regardless of position.

Brentwood Home Cypress Mattress, Gel Memory Foam, 13-Inch

Specs

  • Warranty: 25 years
  • Type: Memory foam
  • Firmness: Medium

This memory foam mattress is a tall option compared to the common 10-inch memory foam mattresses available. You get 3.5 inches of gel memory foam on top, which should provide a cooler night’s sleep. Memory foam is known for retaining heat, which is a good reason to use this mattress on a platform bed. The slats underneath should allow for a bit of airflow, which can contribute to a cooler sleep, as well.

The bed is rated as medium, so it’s a good choice for those who sleep in almost any position. Back sleepers may find it a bit softer than they’d like, but a solid platform underneath could help lend more support. The foam is quick to react to your movements, which means you can shift in the middle of the night and your mattress should respond quickly to continue providing support to your body.

If you sleep with someone who happens to starfish at night (splayed out, leaving you little room on the bed), you may feel a bit unstable because there’s very little edge support, which is a common issue with memory foam mattresses.

R

Pros

  • Plush feel
  • Motion-isolating
  • Gel foam layer for keeping you cool
  • Firmness is good for side, stomach sleepers
Q

Cons

  • May not be great for back sleepers
  • Very little edge support
  • May require deep pocket sheets
If you’re looking for plush softness, a cooler night sleep, and that traditional memory foam support, this Brentwood mattress could work for you in your platform bed.

Nest Bedding Alexander Series

Specs

  • Warranty: 20 years
  • Type: Innerspring Hybrid
  • Firmness: Multiple Options

When it comes to choosing a mattress for your sleeping preferences, it can be difficult to trust what a manufacturer says, which is why it’s so important to read reviews. Even then, what’s soft to one person may be firm to another. This memory foam mattress from Nest Bedding has you choose your firmness level, from firm to medium to soft.

Unlike some other memory foam mattress, this one is made up of several layers that all have different jobs. The thickest layer is the supportive base, which is about 4 inches thick and it’s fairly dense. Just above that is a layer that’s meant to help air circulate through the foam so heat doesn’t get trapped. Then you have layers for comfort and cooling.

At 12.5 inches in total height, it’s a good fit for platform beds. You don’t have to use a box spring with this mattress, but you do want to use a solid foundation, whether it’s flat or slats that are evenly spaced, and not too widely spaced. Memory foam does a good job of isolating movement, too, so you should sleep soundly through the night, even if your partner moves.

R

Pros

  • You choose firmness
  • Motion-isolating
  • Gel layer for cooler sleep
  • Six sizes available
Q

Cons

  • May be too tall for some
  • Very little edge support
This could be the best twin mattress for platform beds thanks to its adjustable firmness, long warranty, and no need for a box spring.

Latex

Spindle Mattress

Specs

  • Warranty: 10 years
  • Type: Latex
  • Firmness: Custom and adjustable

One of the best-rated mattresses is the Spindle mattress. It’s 100% natural latex, but added in different layers, so you get comfort, support, and that bounce you want from traditional innerspring mattresses. In fact, latex offers several benefits you can’t get from memory foam. It’s breathable, so you sleep cooler at night. It’s also antimicrobial, so it combats allergens a bit, which is good news for anyone allergic to dust mites. However, latex can be heavy.

Not only can you use this with a platform bed, the company suggests you do not use this bed with a box spring. A platform bed with slats that are evenly spaced offer support and air circulation, which your mattress needs.

If you find that you’re having trouble sleeping because the bed is too firm or too soft, simply unzip the cover and rearrange the layers. The comfort level is totally adjustable. The biggest downside to this mattress is that it isn’t meant for plus-sized sleepers – if your BMI is above 31, Spindle suggests looking for a firmer mattress.

R

Pros

  • 1-year comfort adjustment
  • Balance between support, bounce
  • Antimicrobial latex is allergen resistant
Q

Cons

  • Not great for heavier users
  • No full refunds
Overall, this Spindle mattress is as firm or soft as you want it to be with adjustable layers of latex, which makes it a good choice for anyone, but it is a bit heavier than most mattresses, so choose a platform bed with good support.

Dromma Bed

Specs

  • Warranty: 12 years
  • Type: Foam, latex, gel
  • Firmness: Medium-soft, Medium firm

The benefits of latex are numerous, which is likely why this hybrid mattress from Dromma gets so many great reviews. You have your choice of medium-soft or medium-firm levels of comfort. Side sleepers may prefer the medium-soft choice, while back and stomach sleepers could find medium-firm the best for a good night’s sleep.

The thickest layer is the supportive memory foam base, but it’s a little different from most memory foam out there. Sleeping cooler is important to many of you out there, and Dromma understands that. The middle layer is a gel layer that offers that cooling feature you want and need. The top layer is made of latex, which gives you that bounciness you want, and the comfort that makes it cozy to snuggle into bed.

The layers of foam, gel, and latex combine to make a comfortable mattress that’s also durable and supportive. It also isolates movement well, so you shouldn’t notice if your partner turns in their sleep. You could throw this mattress on the floor, or better yet, slip into a platform bed with slats for good air circulation and added support.

R

Pros

  • Motion-isolating
  • Sleeps cooler
  • Antimicrobial latex is allergen resistant
  • Springiness without coils
  • Removable, washable cover
Q

Cons

  • Heavy
If you’re looking for mattress that offers comfort, support, and breathability, this Dromma could be the best mattress for your platform bed frame.

DreamFoam Bedding Ultimate Dreams Eurotop Latex Mattress

Specs

  • Warranty: 10 years
  • Type: Foam, Latex
  • Firmness: Multiple Options

A latex mattress offers many more pros than you might expect, given the popularity of innerspring mattresses of big brands. This Dreamfoam Bedding mattress combines layers of memory foam with latex to create a more breathable foam that sleeps cooler than you’d expect. Because it has a memory foam base and latex topper, it isn’t as heavy as a pure latex mattress, which makes is a good choice for platform beds that could have strict weight capacities.

It’s a firm mattress if you want it to be, but the latex offers a level of comfort that you don’t usually get with just memory foam. It’s generally considered a medium firmness, so it’s that good in-between for softness and support that works well for all sleeping positions.

The latex layer adds the bounce you may have missed from innerspring mattresses and that you don’t get with a memory foam bed. The 12-inch height of this mattress makes it a good choice if you plan to slide this into a platform bed.

R

Pros

  • Pressure point relief
  • Sleeps cooler than traditional foam
  • Plush top
Q

Cons

  • May be too soft for back sleepers
  • Heavy
If you’re looking for a memory foam and latex mattress that sleeps a bit cooler for a platform bed, this Dreamfoam Bedding mattress could be a good choice for you.
