Conventional foam mattresses are great for people who desire all-around comfort while still wanting proper support. The softness provides relief and alleviates pressure but maintains a firmness that supplies proper body support. Specific product capabilities are dependent on the foam type(s) and additional options selected during mattress customization.

Custom foam mattresses are foam only.
Covers may be purchased under Mattress Accessories.

Foam Types: All Conventional Foam
Sizes: Standard and customized sizes available
Heights: 1, 2, 3, 4, 5, 6, 7 and 8 inches

Foam meets CertiPUR-US® certification.

Return Policy
Custom mattresses cannot be accepted for return unless there is a product defect or a manufacturing error. Please see our Return Policy for more information. If you have questions concerning our return policy, please Contact Us before placing your order.

Manufacturing Tolerances
Custom-cut mattresses and toppers have dimensional tolerances according to the "Custom-Cut Mattresses and Toppers" section of our Dimensional Tolerances table. If your project requires a tighter tolerence, Contact Us for more information about machine cut custom items.

Largest Solid Mattress
The largest solid mattress size available is 76" x 82". When a mattress is ordered larger than one or both of those dimensions, it will be made from two pieces of foam that are glued together. There are no additional gluing charges for oversized mattresses.

Largest Solid Thickness
The largest solid mattress thickness available is 6". When any one mattress is ordered at a greater thickness than that, it will be made from two matching foam pieces glued together to achieve the desired thickness at no additional charge.

We ordered two pieces of 6" high density foam for twin beds in our RV. They are prefect! Reasonably priced, very fast shipping and quality product!
Just what I wanted

This foam is very dense and strong. It is cut perfectly to my specs. I am making a mattress for a child’s bed at a summer place. I will order more from this sight.
Super Happy!

I am extremely pleased both of my foam purchases. I ordered a 4” size for a twin bed and a 3” size for my queen bed. I was so happy to find a company that cuts the foam to the exact measurements you provide them. I previously had ordered from a company that did not have this option and when their standard twin foam arrived it was 12” to narrow for the bed. The quality of the foam from this company is far superior to any foam I’ve had previously as well. Great service, quick arrival and great product!!
Wonderful product

We ordered a custom sized foam mattress and are thrilled with the product. The mattress arrived quickly and is cut perfectly. The information on the website made choosing the correct product a breeze. We have been recommending Foam Factory to everyone we know!
Best customer service around and stellar product

Some of the best customer service I’ve experienced at any company. Walked me through everything important to check for my application. Product came as described and quickly. High recommended!
Quite pleased!

The foam I ordered was perfectly measured. I am happy I chose to have the dacron wrap, although, I wish there were a better method for fastening it. I made my own under covers and outer covers and am very pleased with the end result. The cushions are very comfortable for sitting. I haven't slept on them yet, but I don't think I will be disappointed. I would recommend this product to others and will order again should I need foam for another project.
Excellent product

Was very happy with my order. Had concerns as some of the reviews seemed negative. The foam mattress arrived quickly. Was easy to open. Is great to sleep on. I highly recommend foam by mail. Product is easy to order, arrives quickly and is exactly as described.

I purchased a sheet of high density foam for an extra long twin bed. My purchase arrived promptly and upon opening the packaging the foam relaxed. I was able to use the foam within a few hours. I would highly recommend Foam Factory and plan to do more business with them in the future.
This will be the only place I use

I needed custom sizes for a loft/bunkbed. Every question (there were many) was patiently responded to. The price was comparable to other suppliers. The items arrived early and was perfect. I already have another project I'm gonna order foam for.
Good value, flex design
