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.

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

This is my third mattress I’ve ordered from this company and every one of them has been more comfortable than any bed I’ve ever slept on. Great product and great people. Thank you!
An excellent experience

Kandi Sheets | June 8th, 2022
Ordered a custom cut foam mattress. Installed the mattress to find we should have given ourselves about an inch more leeway. Mattress fits tight for sheets because of that. Regardless, slept like a champ. This bed is absolutely comfortable. Had it made to fit in our RV Roadtrek. Recommend anyone looking for a custom fit mattress. Foam Factory is the place!

Custom size fit perfect.
Ron Landis | March 16th, 2022
I needed a new mattress for my van conversion I recently remodeled, so I purchased a 4" mattress of the highest quality. It was cut to my specs and showed up at my door a few days later. It fit perfect I just needed to trim the back corners a bit which I did easily with an electric knife a friend loaned me.
Awesome product
SHARI WHITMAN | March 15th, 2022
Ordered a 7" thick custom mattress for our travel trailer and are very happy with the results. Garrett, from the company, called me personally to discuss the type of foam appropriate for our needs and he was knowledgeable and made the perfect recommendation. The custom cover is also perfect. High quality, made custom to your specifications with fantastic customer service. From order to delivery to my house was approximately 7-10 days. We will be using them again to replace the mattress in the master bedroom in the travel trailer as well. Highly recommend this company and their products.
Wonderful firm mattress for big guy
Gene | December 16th, 2021
I just received my custom lux hd 6" foam mattress for a vintage mid-century modern bed. It is very firm and provides great support for me at 220 lbs and my partner at 125 lbs. It came quickly, the custom size is perfect and I'm so happy with it.
FANTASTIC Mattress
wayne scott | October 9th, 2020
I ordered a custom "FOAM FACTORY" LUX FOAM HQ mattress 4inch thick, with the dacron wrap, and the custom striped cover for a folding, double person, "Kamp Rite Tent cot". The folding cot is a non standard sized cot, and has a metal support bar running the length of the cot, right down the middle. Without my new custom foam mattress my wife and I would probably be forced to sleep apart, divided by the center support bar, because sleeping on top of it would be very uncomfortable. Now, theres on separation, or division between us thanks to my new mattress! The LUX HQ foam offers fantastic comfort,while providing excellent support for my back issues. I love this thing so much that I bought another one just like the first one for my other folding camp cot!
Great product
James | March 19th, 2020
Replaced the foam on our 16 year old bed. Now it is like new again. So glad to have found this company.

Barbara | March 18th, 2020
We ordered two custom sized foam mattresses for our children's antique toddler bunk bed. The kids have been sleeping all through the night and absolutely love their beds. The whole order was a smooth process from the website navigation to the fast delivery. We are very pleased and we are going to order our camper mattresses and couch cushions soon also.
Excellent back support
lah | March 11th, 2020
This is second foam mattress purchased from foam factory. So liked the first that I purchased a second. My lower back will not tolerate and kind of soft or even "firm" mattress. Extra firm is it preference. This foam mattress is perfect. Does not sag or deteriorate with use. No toxic oder at all. I have a 4" mattress over a slated wood frame. Mattress feels solid, flat and extra firm. I purchased the striped protective cover. It is simple, classic old world look and great mattress protector. Fits tight, no stretching out or wrinkling. Very pleased with the purchase. Foam Factory is awesome. That you can choose custom sizes is great. They are reliable, excellent products, no flash, just great service and high quality goods. Thank you!
great
gloria rubino | March 5th, 2020
This is really a high quality foam. It will last for years and years I am sure.
Just what I needed.
Stephen G Finn | February 26th, 2020
I needed a small fill in piece for my RV bed. They did a great job and I was also able to have them make a custom size zippered cover. Everything came out great, timely and perfect fit.
Perfect
GW | February 26th, 2020
Ordered a replacement mattress for my RV. Custom sized for a perfect fit and very comfortable.
My lower back is grateful.
Frankie B Washington | February 19th, 2020
I purchased this mattress because we really needed something with support on our click clack beds. The previous foam support my wife purchased was murder on my lower back. I had surgery last year there and it was definitely not helping it. With this new foam mattress it has fantastic support and overall comfortability. So happy that I came across this retailer and product ;)
two foam mattresses
Lynn Robinson | February 12th, 2020
I ordered two foam mattresses to replace the hard pad that comes with port o cribs. Perfect fit; love them

The Denver Company mattress that came with our RV was killing us. We are thrilled with the comfort of the replacement AND the price! Thanks!

Robin | January 8th, 2020
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
Josh | January 8th, 2020
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.
back for more
Elle | January 5th, 2020
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
Marlon Valle | January 3rd, 2020
We have a custom made bed for my toddler, which is special dimension. The quality of the foam is outstanding and my son is happy sleeping back in his bed. Thank you so much A+
Perfect
Carlisle | January 2nd, 2020
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!
Perfect product and experience!
Tim McKenzie | December 26th, 2019
The company, the products, and the customer service far exceeded my expectations! Everything was GREAT!
I am so happy!
Roseann | December 26th, 2019
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.
1” med-firm mattress topper.
Susie Marsh | December 18th, 2019
This is just what I needed. I am already having less back pain. I would advise other people use this Company.I give them 5 ⭐️
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.
I love your product and service.
Nancy | December 11th, 2019
Was custom cut to perfect size. Perfect firmness! I love this mattress as much as the latex ones too.
Just what we needed!!
Suzanne Sanstead | December 4th, 2019
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
Andi | December 4th, 2019
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!
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!!
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!
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!
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.
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.
Just what we needed
Ron | July 17th, 2019
Special size ordered online fit area fine quality product
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.
This will be the only place I use
Kelly | June 25th, 2019
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.
