Whether you have just purchased a memory foam mattress or are planning to, you’ll need a stable base for your new bed.

Unlike innerspring mattresses, memory foam beds are prone to damage if used on the wrong foundation. Innerspring mattresses only need a supportive flat structure to rest on. Foam mattresses need a supportive, flat surface with a solid structure. For example, if pairing your foam mattress with a platform bed, the slats should be three inches apart or fewer to sustain the mattress’ durability and protect your warranty.

In our article, we discuss our top options for memory foam mattresses and explain the difference between box springs and other popular foundations. We’ll also discuss which bases are most compatible with memory foam mattresses.

The Amerisleep Mattress Foundation has a modern, clean-lined style. The slats are no more than three inches apart, providing strong, proper support to enhance the performance of a memory foam mattress.

The slats are completely enclosed in non-slip fabric, keeping the mattress hygienic and stop it slipping across the foundation’s surface. The non-slip fabric surrounding the slats distributes weight evenly, which is crucial to the mattress’ durability. Its design helps a memory foam mattress breathe.

FUN FACT: Air circulation is essential to a foam mattress, it enhances the longevity and comfort of the mattress in several different ways. It also helps you keep cool at night.

The bed base was designed to be set up without tools. The joints just click into place.

The height of this foundation is adjustable. For those who like a low profile bed, placing the foundation directly on the ground is a valid option. Amerisleep does suggest to leave the legs on for proper air circulation.

For those who want a little extra height, the wooden legs add 4.75 inches.

Why Do the Slats Need to Be Less Than 3 Inches Apart?

The Editors of Sleep Junkie highly suggest getting a foundation with slats no more than three inches apart and at least 0.5 inches tall. Adhering to these conditions will provide a setup promoting a solid surface supportive of the sleeper and bed, and prolongs the memory foam’s life.

Mattress bases not meeting these recommendations may cause premature material disintegration. The wider the slats are spaced, the more material is allowed to dip below the slats. If sagging between slats occurs, the mattress’s weight will press more generously on the slats, which quickens material decay and increases the risk of sagging and indentations.

Types of Foundations

It’s good to know your options. A large part of shopping for the best mattress foundation is learning which bases will work for your mattress.

Box Spring Alternatives

Bunkie boards are one of the many cost-effective alternatives to box springs for foam mattresses. They’re flat objects constructed from plywood or particleboard. Usually, they are placed on top of a box spring or the rails of an existing bed to ensure good support.

Steel Grid Platforms

This type of bed functions very much like a platform foundation, but instead of being made of wood, the grid platform is made entirely of metal. The mattress surface is designed as a grid of wide-spaced rectangles.

Even though there are many bloggers stating this base stands as a good option for memory foam mattresses, we would have to disagree. Steel platform beds do not meet the three inches apart or less rule. The grid design doesn’t have many points of contact, potentially leading to mattress indentation and eventual sagging.

Adjustable Foundations

Similar to platform beds, adjustable bases provide a flat, solid surface for your foam mattress. What makes this foundation unique is that you can raise and lower the head and foot of the bed for comfortable reading and watching TV. This bed is used for medical purposes because it allows you to angle your head slightly above the hip, decreasing the risk of acid reflux or obstructive sleep apnea.

Platform Beds

Platform beds offer an affordable modern design without the use of a headboard and comes in varying profiles. Depending on the bed’s height from the floor, this foundation offers good under-the-bed storage. Some platform beds come with adjustable legs; although, there are others that don’t. Look into the platform bed’s legs if you want under-bed storage.

Because platform beds use a solid board for support instead of slats, they may not offer sufficient ventilation, which may result in heat retention. If you’re worried about heat build-up, consider a cooling memory foam mattress.

Panel Beds

Sometimes called wood slat foundations, panel beds are made of wood to create a solid structure supportive of the mattress’s weight. The closely spaced slats allow the foam to breathe.

The Floor

Best Foundation for Memory Foam Mattress

Placing a memory foam mattress on the floor is both a viable temporary and permanent option. The floor is a solid, flat surface to give uniform support. In other words, it meets all the requirements needed for a supportive surface, although the lack of air circulation through the bottom of the mattress can lead to heat retention.

Frequently Asked Questions

What do you put under a memory foam mattress?

For proper support, many people place a mattress foundation between their memory foam mattress and their bed frame. That said, memory foam mattresses don’t need any extra foundations or box springs when paired with platform beds or adjustable bed frames.

Please note, box springs by themselves should not be paired with memory foam mattresses because they offer uneven support which can damage foam layers.

If you have a box spring you’d like to put under your memory foam mattress to give the bed extra support or height, make sure to place a bunkie board or 3/4-inch piece of moisture-resistant plywood between the box spring and the mattress. Doing so creates a solid, flat surface for the memory foam mattress.

Can you put a memory foam mattress on top of another memory foam mattress?

You technically can place a memory foam mattress on top of another memory foam mattress, but it’s not recommended, and doing so will probably void your mattress warranty. Memory foam mattresses need solid, sturdy support, and since memory foam mattresses are contouring and cushioning, they don’t necessarily provide solid support, meaning it’s not a great idea to place a foam bed on top of another foam bed.

Should you use a box spring with a memory foam mattress?

Box springs should not be paired with foam mattresses because they can damage the foam layers. That said, if you have a box spring currently and would like to use it with your new memory foam bed, you still can. Just place a bunkie board or piece of moisture-resistant plywood between the mattress and the box spring to create a solid, flat surface for the foam layers.

Do you need a special bed frame for a memory foam mattress?

You don’t need a “special” bed frame, so to speak, but memory foam mattresses do require a certain level of support. Most memory foam mattress warranties will specify that the mattress should be kept on a solid or slatted surface with slats no more than 3 inches apart. Most mattress foundations and platform beds meet this requirement, so it’s not terribly difficult to find a compatible bed frame for your foam mattress.

Can you put a memory foam mattress on the floor?

You can place a memory foam mattress directly on the floor, but we don’t recommend it. Placing your mattress right on the floor makes it more susceptible to dirt, germs, and moisture build-up, and moisture within your mattress can damage its foam layers and cause premature deterioration. While placing your mattress on the floor works as a short-term solution while you find a bed frame, it’s not the best long-term set-up.

Did You Find The Best Foundation?

You’re now armed with some solid knowledge regarding the best memory foam foundations and you’ve seen a few affordable options on the market today. All you have to do is make a decision and wait for the package’s arrival, unbox, and roll out your new foam mattress on your new foundation.
