If you've recently found yourself in need of a new foam mattress, you may be interested to learn that you can make your own foam mattress in just a few easy steps. With this helpful guide and a few easily obtainable tools at your disposal, you'll be able to make a brand new foam mattress in a simple and stress-free fashion. Read on to learn everything you'll need to know.

Step 1 - Make Your Preliminary Measurements

Before you rush out to purchase the materials you'll use to make your new foam mattress, you'll need to make some preparatory measurements. Start by using your tape measure to determine the height and width of the bed frame upon which you intend to place your new mattress. Even though this is perhaps the most cumbersome task associated with the mattress making process, it is important that you take care to make your measurements as accurate as possible, as they will ultimately determine how much material you will need to purchase.

Step 2 - Purchase Your Foam

Now that your measurements have been taken, you are ready to go foam shopping. You should be able to purchase large sheets of foam at virtually any craft or fabric specialty store, so there's no need to go out of your way to locate the required materials. Don't forget to check the foam's tag for its list of materials, especially if you have any respiratory allergies or skin conditions; some kinds of foam can be toxic. It is highly doubtful that you will be able to find sheets of foam that conform to the measurements you took, but don't worry because you can use your handy construction knife to cut them down to size once you get home. It may interest you to learn that many stores will perform the cutting process for you, so when you're out shopping, be sure to have your bed frame measurements on hand. It is generally recommended that you purchase two sheets of solid memory foam and a single layer of extra firm foam in order to ensure that you get the proper amount of support when sleeping.

Step 3 - Prep Your Bed Frame

Now that you've acquired your three layers of foam and subsequently cut them down to their proper sizes, you're very close to being finished. Carefully place a half-inch piece of solid plywood on your bed frame's base before laying your new mattress on top. Make sure that your foam has had at least several hours to uncurl before inserting it into your bed frame. Be sure that the foam is fully uncurled and that all of its fumes have been aired out before placing a mattress cover over it.
