How to Build a Memory Foam Mattress Foundation: 6 Steps Guide

How to Build a Memory Foam Mattress Foundation 2023

A memory foam mattress can give you the necessary softness and firmness to get a good night’s sleep. However, a reliable base is required to enjoy your bed fully.

This article will show how to build a memory foam mattress foundation from scratch using affordable and readily available materials.

Whether you’re a DIY enthusiast or a complete beginner, this guide will help you create a foundation to support your memory foam mattress for years.

Step 1: Measure Your Mattress

Measure the dimensions of your memory foam bed using a measuring tape. This will help you determine the size of your foundation.

Step 2: Cut the Plywood Sheets

Cut the plywood sheets to the size of your mattress using a circular saw. You will need two sheets for a twin or full-size bed and three for a queen or king-size mattress.

Step 3: Sand the Edges

Sand the edges of the plywood sheets with sandpaper to remove any rough edges or splinters.

Step 4: Attach the Plywood Sheets

Lay one of the plywood sheets flat on the ground. Apply wood glue to the edges of the second sheet and place it on top of the first sheet.

Repeat this step for the third sheet if necessary. Once all the sheets are stacked, drill screws through the sheets every 6 inches along the perimeter.

Step 5: Add Supports

To add extra support, cut four 2×4’s to the length of your foundation. Attach them to the corners of the foundation using screws.

Then, cut two more 2x4s to the width of your foundation and attach them to the center of the foundation.

Step 6: Add Legs

Raise your base off the floor and give it more stability by affixing legs to the four corners.

The legs need to be firmly attached to the frame, and they need to be the right height for your bed.

While particleboard is a cheaper alternative to plywood, it may not provide the same level of durability and stability.

We recommend using plywood for the best results.

How much weight can the foundation support?

Your foundation’s weight capacity depends on the plywood’s thickness and the number of support beams.

However, a properly constructed foundation should support the weight of your mattress and two people without an issue.
