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.

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.

Just what I wanted
Norman | March 4th, 2023
So great to be able to order custom foam like this. I used it when I wanted an extra thick foam under my shag rug, so that I could lie on it extra comfortably. Email customer service from Haley was excellent, helping me through every step of the order. I really enjoyed receiving samples of three different types of foam to help me make my selection.

Exceptional Quality

This is the second custom foam mattress I have ordered from Foam Factory. It meets all my expectation with the quality and comfort the mattress provided. I will definitely order from them again in the future.
Mattress purchase

Ordered custom mattresses for my camper. They arrived quicker than expected. They were exactly what I ordered. We are happy with them.
Wrong item but fully rectified
Bob bair | February 22nd, 2023
We ordered a foam mattress for a youth bed for our visiting grand son. They promised it would get here on time for their visit. The mattress we received was foam the size of a chair ottoman . When I told them I needed it in less than a week they made a new one and it got here in just a couple of days. Mattress was the perfect size for the bed. Great customer service.
Excellent Service!!
Andy | February 21st, 2023
Great service!! Easy to order. The foam was cut to my required dimensions and the striped cover with a zipper is a great addition. This company is highly recommended.
Sam | February 21st, 2023
Got the lux foam 8" for a very large in height and weight person and it's great. I could see it being to firm for someone under 200 lbs, but for larger folks this works great
Just what I ordered
Edouard Duroux | February 21st, 2023
Sized perfectly - ordered a replacement piece of high density foam for an RV mattress. Love the free shipping.
Lucy | February 8th, 2023
Ordered custom cut foam for a day bed and it's perfect! It fits perfectly and it's very comfortable!
Exactly what I wanted!
Rebecca Arena-Bland | February 1st, 2023
My mattress came promptly and was exactly as I ordered. It fluffed up within minutes and is very comfortable.
Great quality, but 6” is too firm for mattress
Larry Beasley | January 29th, 2023
Great company, with fast shipping I have no complaints at all besides I wish I understood the different thickness levels better before purchasing, I purchased the 6” HD36 foam to use as my mattress in my Van RV Conversion and it is just way too firm. I was afraid it wouldn’t have been firm enough actually I almost order the 8” again not really there problem just wish I understood it better
Excellent support!
Sarah Pogell | January 16th, 2023
My mother is difficult to please, but she loves, loves, loves her premium foam mattress. It works great on her electronic hospital bed, whose head and foot can be raised and lowered. Thanks for the quick service, too!
Dan | January 16th, 2023
Got a custom cut lux foam - HQ. Really like the foam. Firm and supportive but not too hard.
Great fit, great quality!
David Oehlschlaeger | January 13th, 2023
I’m a 6’8” tall man who has trouble finding just about anything to fit me—including a mattress! With their custom sizes, Foam Factory came through in a big way for me. I was able to get the perfect sized foam mattress to fit my current bed frame. It feels like good quality foam and is comfortable to sleep on. I would highly recommend this company for all your foam needs!
Great product fit perfectly
Marcus | January 3rd, 2023
Fits perfect and very comfortable
Perfect fit
Ramona | December 29th, 2022
I have not slept on the 5" foam mattress yet but it is plush and was cut precisely to the measurements I specified for a make shift camper.
Perfect fit, finish, and quality
BR | December 22nd, 2022
Ordered 2 custom cushions with striped covers to fit our treehouse loft. Chose the higher quality foam to last longer with outdoor temperature changes. The mattresses fit the loft space perfectly. The striped covers are also a good quality, and are helping keep the foam clean. Will definitely use in the future for any custom foam needs.
Foam cushions
Paula | December 6th, 2022
I have ordered 3 foam cushions for under window seating and they are perfect!
Perfect fit!
Emily | December 4th, 2022
Bought a custom mattress to add to the top of a Pottery Barn Teen fold out couch that has a pad that folds flat onto the ground. The addition of the custom mattress makes it much more suitable for adult guests. I called to get some advice and the person on the phone was very helpful. It shipped very quickly and we are very happy with our purchase. We also bought a cover which makes it very polished.
Special order mattress for antique bed
Patty | December 1st, 2022
Great quick service.and exact size ordered. Fit perfect on antique bed. Thanks so much.
Excellent bench cushion
Marta | November 27th, 2022
I ordered the high density foam mattress to make a pillow for the bench in our living room. The cushion is perfect! Very comfy, with the exact measures requested, it arrived very well packed and the shipping was fast. Very happy with this purchase. I highly recommend this product and Foam Factory. Thank you!
Perfect fit!
Amber | November 22nd, 2022
Ordered a custom size memory foam mattress for my daughters 'tent' that she prefers to sleep in rather than her bed and it came out perfectly. I feel much better knowing she is sleeping on an actual mattress, and she's happy she can sleep in her 'tent', a win-win! Shipping was also way faster than I expected. Received it about 10 days after I ordered it. Will definitely come here again if I need any other custom cushion.

Garret at Foam by Mail is a life saver. I had ordered a firmer foam on line and he reached out to me to suggest I go down in firmness and he was 100% right. I love how our sofa turned out. It is perfect. This company is top notch in my book.
Excellent product
Esperanza | October 30th, 2022
My husband and I have ordered quite a few foam mattress's from your company and always received great customer service and excellent products. Thank you.
Two pieces
Zoe | October 25th, 2022
I ordered to oddly shaped pieces (not your typical full size mattress). They came very quickly and it was communicated very clearly when I might expect them. The foam was great to finish a captains bed I built. I would definitely order from them again.
Much more firm than i expected
Linda Crowther | October 25th, 2022
I am very happy with the service and quality of the product !! I ordered a custom sized HD 36 Foam 6" mattress for my RV, and also purchased the white striped cover (custom size). It is too firm - and i am thinking possibly that the striped cover is so tight that it does not allow the mattress room to 'give'... I would take the striped cover off, but it is so tight, i am afraid i will never get the mattress back in that cover. I have recently ordered a poly foam topper (3") to see if i can soften it up a bit. I think the pictures portraying the foam with 'give' is a little misleading. I .will see if the poly foam topper helps !
Good matress
Jake | October 25th, 2022
Bought a custom mattress, fits great and came quick.
Great product!
Daniel | October 23rd, 2022
I've been using my custom mattress for a couple months now. Wanted to use it before reviewing. The mattress is very nice and comfortable. Quality is great. If I ever need another foam mattress, I'll definitely order again.
Quick delivery, great quality
Kevin | October 11th, 2022
Got my order less than a week after I ordered it, and the foam is very high quality. Only reason it was 4 stars and not 5 was because my sections were cut about a 1/2 inch too wide, so I had to trim them a bit, myself. Still, would definitely purchase again, next time i needed. :)
Great for Rooftop Tent
Dustin | September 16th, 2022
This is a great option for additional cushion in my rooftop tent. Very pleased with the quality for the price.

Foam mattress purchase
Tom Martin | September 6th, 2022
Shipped fast and fit perfectly Thank you!
All Expectations Met!
Tim | August 28th, 2022
A great purchasing experience and I would definitely recommend Foam Factory. I needed three custom pieces for a bed/bench combo I was using for a build out of a Honda Element into a mini camper. There were many options and the pricing was very reasonable. Pieces arrived quickly and the quality was top notch. I ordered the Lux foam for the slat portion and it is firm enough that I do not need a flat board to compensate for the 2"+ gaps when in bed mode. It works perfectly and is definitely a firm mattress. Thank you Foam Factory, I love it!
Perfect replacement!
Steve W | August 26th, 2022
My mom needed a new mattress for her antique bedroom set which was a non-standard size. Being able to custom order to its dimensions made for a perfect fit!
Great Job
MJ | August 22nd, 2022
Custom mattress for our van was built exactly as requested with rapid completion and shipment. Perfect
Perfect Fit!
SH | August 21st, 2022
Beautiful fit! I do wish I had orderer a slightly softer one, and I am sure it will break in with time. I am also a soft cushion person. Thank you for this cushion and our space is amazing!
Not as described on the website
Joe Sembrat | August 19th, 2022
I purchased the mattress to replace one in my RV because the original was too firm. The description of the new one I purchased made it seem that it would be less firm than the one I bought. Turns out that the two are the same - very firm
Harvey pedigo | August 19th, 2022
I bought a 7 " thick foam mattress for a bed in my van. We are going to sleep good !
Great product and support!
Mel | August 16th, 2022
I ordered a single 5" cushion to replace three couch cushions (couch is being used as a bed). It is excellent. It is very firm, so I added a softer topper & it is working very well. I am so thankful to be able to have cushions custom cut, not to mention so quickly! Now that I have the measurements right, I am probably going to order another in a somewhat softer foam to see which works best/is most comfortable for my mom. I do want to give a big thank you to the agents who help you figure things out when you call them, and to the agent with whom I spoke after placing the order. I could not be more impressed with the very thoughtful and swift assistance given both by phone and by email. Thank you!!!
Custom Size Cradle Mattress
Elizabeth Hernandez | August 15th, 2022
I ordered a 3" x 14" x 34" lux foam with dacron wrap to use as a mattress for the family cradle. The cradle was built 31 years ago specially for when my fiance was born. It's been passed down for every baby in the family since he was born and we'll be using it for our little baby when she comes home from the NICU. The cradle isn't the standard size of bassinets or cribs so the original mattress had been custom made by my fiance's grandmother, and though the mattress and the cradle are both in incredible condition, I felt I needed to replace the mattress since it's 31 years old. I'm very happy with the new mattress that I ordered from the Foam Factory. It's very firm as is necessary for a tiny newborn and it was quite affordable. It happened to fit perfectly in a king size waterproof pillow cover. I will likely order from Foam Factory again for her crib mattress.
Custom mattress for my boat.
Brad Schaffer | August 8th, 2022
I ordered a custom mattress and cover for a new boat I purchased. It arrived in 8 days from the day I ordered. It fits perfect and is extremely comfortable. Highly recommend this company. Also they were less expensive than everywhere else I looked.
Arrived early, very comfortable
Niels | August 7th, 2022
Great customer service. Arrived earlier than the original estimate and was exactly as specified. Very comfortable an, definitely coming back for the remaining pieces to our "teenage hangout area"
Great Service!
Mel | August 2nd, 2022
Received very helpful, kind assistance from Foam Factory/Foam by mail agent as I tried to figure out what I was doing and which type of foam I needed to order. I was so happy and surprised at how very quickly the order was completed and I received the nicest custom cut dacron wrapped HD36 HD foam for a couch which is being used as a bed. It is working very well, but my measurements were off, and I've placed a second order which has also been shipped in record time! Thank you so much - The foam is very firm, and I added a soft topper. I also ordered 7" height which was too tall. very thankful for this service as I was trying to figure out how to cut a twin size regular mattress down to size. This is so professional and just PERFECT for the couch, and hoping I figured the height correctly this time! THANK YOU
7" HD36 Foam Mattress
Hunter | August 1st, 2022
Firmer than I thought it would be and great for a side sleeper! Arrived quick and in great shape. Also ordered the cover for it which has proved valuable already.
