How To Put Plywood Under Memory Foam Mattress?

Placing plywood under a memory foam mattress may sound complicated, but it’s a simple DIY you can finish in minutes.

Simply follow this process with three simple steps, and you’ll be on your way to a better night’s sleep, especially if you are a light sleeper.

Step 1: Measure

Start by measuring the bed foundation’s surface area. The hardware store can cut a panel of plywood to the desired size. To be durable and sturdy enough to give support, it must be at least 3/4 inch thick.

Utilizing a less than 3/4-inch-thick board is not a good idea. The board will fracture, making it unsuitable for a mattress or for an adult to lie down. Besides, the panel should be at least 3/8 inches thick, while it must not be thinner than 3/4 inches.

When determining the thickness of the panel, consider the weight of the cushion and the height of the person who will be using it.

Step 2: Install

To install the plywood, simply place it on top of the bed frame or the box spring, making sure that it is centered and flush with the edges. If necessary, you can use screws to secure the plywood in place.

Lift the mattress, either half or full, and lay the trimmed panel on the foundation. Then, reposition the mattress on the top.

Step 3: Test

When moving around or lying on your bed, try to detect any creaking or bending from the foundation. You’ve successfully inserted the foundation if you can’t hear any sound.

Are Box Springs Good For Memory Foam Mattresses?

Box springs have springs or coils that can prevent a memory foam mattress from evenly dispersing your weight, which over time can lead to the mattress sagging or developing an unattractive appearance.

In addition, the springs can work as shock absorbers. They take the pressure off the mattress on top of them. A typical form of box spring foundation, in general, is not ideal for this kind of foam. They’re more likely to work for innerspring mattresses.
