What Is a Mattress Joiner?

A mattress joiner is a piece of foam that is used to join two mattresses together, thus merging them into one. The bed bridge fills the space between the two mattresses, preventing the sleeper from falling into the breach between the beds.

Typically, a bed bridge is used to convert two twin beds into a king-size mattress. When installed and used properly, a bed bridge can be an excellent low-cost choice for expanding your sleeping space without having to spend $1,000+ on a king-size mattress.

Do You Need a Mattress Joiner?

When two smaller mattresses are used to construct a double bed, the gap between them is created. Occasionally, a larger mattress can be delivered in two pieces.

Two distinct mattresses might be very beneficial for couples with varying body types and weights. Each spouse can then choose the mattress that is ideal for them, taking into account their preferred sleeping position or mattress firmness.

What Comes in a Mattress Joiner Kit?

Mattress joiners are a simple and practical technique to convert two twin beds to a king. They are connector kits that include a large center piece that goes between the two mattresses and a strap that runs around the perimeter of the newly completed king bed, securing the individual mattresses.

Whether you’re merging guest beds to create a larger bed or combining hotel beds to create a more pleasant vacation stay, mattress joiners are an excellent alternative for increasing the versatility of twin beds.

How Do You Use a Mattress Joiner?

Installing a mattress joiner is a process that follows just a few steps:

  • Open the package and allow the foam joiner to return to its original size.
  • Join the two mattresses you want to connect and insert the foam part inside the gap.
  • Wrap the belt completely around the bed and through the strap. Buckle and secure.

Pros and Cons to Using a Mattress Joiner

As with every other product, there are advantages and drawbacks to using a mattress joiner.

  • Pro: They are very easy to install. It’s mostly about fitting the foam between the bed and adjusting the belt as needed.
  • Con: They don’t always lie flat. That means that you’re likely to feel a bulge where the joiner rests.
  • Pro: You can repurpose old mattresses. A mattress joiner makes it easy to turn two old twin beds into a king one.
  • Con: They sag pretty fast. A mattress joiner doesn’t have the same support system as an actual mattress.

What to Look for in a Mattress Joiner

— Straps

If you’re not the type of sleeper that tosses and turns a lot when sleeping, wedge-style bed bridges can simply connect two twin beds.

They can give all the security you need to keep the mattresses together when covered with a king-sized fitted sheet. Additionally, straps can be purchased individually in the event that you require additional support in the future.

— Size

First, before anything else, consider their size. Ascertain that the bed bridge fits snugly against the gap between your mattresses and does not sag in the middle.

— Bed Perimeter

Don’t you hate purchasing a product that you believe will meet your needs, progressing to the final step of the installation procedure, and discovering that it will not function in your specific situation?

Before purchasing a mattress joiner kit, take a measurement around the perimeter of the two beds you wish to join and compare it to the length of the accompanying strap.

— Material

Another critical thing to consider is the material. Typically, the majority of bed bridges are constructed with a bamboo top. It’s common for a mattress joiner to be filled entirely with foam.

— Extra Features

Additionally, you should check for a few critical additional qualities. Here are a few examples: a compact storage bag for when you’re not using the bed bridge, a bed strap to help keep the mattress together, and instructions on how to correctly install the mattress joiner in question.

— Price

If you’re interested in purchasing bed bridges, you can typically expect to pay between $20 and $150 for some of the most durable models. The price range will vary significantly depending on several factors, including the brand, material, and amount of additional amenities offered.

In Conclusion 

When you locate the appropriate mattress joiner kit for your needs, a whole new world of possibilities becomes available, particularly in hotel rooms or guest bedrooms. 

Consolidating furniture and repurposing it for your space can save you hundreds of dollars over the cost of a new bed. Mattress joiners are an attractive, low-cost solution to a potentially costly dilemma.
