Features

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.

36X79 Big Rig Mattress Topper

I ordered a custom cut mattress topper for the bed in my Semi truck. Perfect fit! Love the zip on coverlet for easy cleaning.
Sencond mattress
Linda Firgard | January 8th, 2020
I purchased a custom mattress about 6 mos ago and loved it but it was as a bit firm. Just ordered another softer to add to it and it is PERFECT! Best part is that even purchasing 2 was less expensive than going out and getting a regular mattress. Although I did order the exact same size the new one was a bit smaller so if you think you might want 2, buy them at the same time.
Custom 4” mattress

I ordered a 4” Custom fit HD36 foam- HQ mattress for the back of my F-150 camper set up. I’ve been sleeping on it over a week now every night and I’m am so happy with it. Super comfortable and is breaking in nicely. I’m 150lbs and the 4” is plenty thick. I wouldn’t be opposed to going 5” next time around to just feel even more comfy. I’ll def be back to order another if/when this thing starts to show too much wear. I ordered the striped cover for it as well to keep it lasting longer.

Ordered two custom foam mattresses with zip covers in 2016. These have held up great so am back to place another order.
Very Happy with my purchase

I used my custom mattress for an SUV camper build/overland vehicle that I engineered and this mattress was perfect for the maiden voyage to Bryce Canyon. Even the person I was with had doubts about comfortable the mattress would be, but it provided a good nights rest. Awesome!

I needed a little extra cushioning for a day bed I had bought which was hard to sleep on. I measured and ordered a 3" foam and the zippered cover and now it is perfectly comfortable and the exact size. Fast shipping too.
Perfect product and experience!

Was custom cut to perfect size. Perfect firmness! I love this mattress as much as the latex ones too.
Amazing!
Linda Brede | December 11th, 2019
I bought the custom super soft foam for my husband. He sleeps in a chase lounge because he has to sleep sitting up. He is disabled. He was always complaining that he was so sore when he woke up. I got the 3" inch thick super soft one and he loves it. This really has helped him to be more comfortable over all.
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.
Just what we needed!!

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!
Wonderful product
Jennifer | November 8th, 2019
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!
Super Happy!
Jill Beedle | November 12th, 2019
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!!
Best customer service around and stellar product
Josh | October 16th, 2019
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!
Excellent product
JB | September 11th, 2019
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.
Quite pleased!
Cheryl Gallien | September 11th, 2019
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.
Very satisfied customer
Jean Curran | July 10th, 2019
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.
Just what we needed

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
