You can trim the edges or stack layers for extra thickness to customize our foam in a way that perfectly meets your needs. Foam can also be glued together to create wider pieces or layered upon one another to create thicker cushions. Foamrush foam can be cut and customized to whatever size or shape you need.

  • Great Value
Color: Gel Foam + Mattress Cover Size: Bunk (48" x 72")
Perfect fit. Quality product, very comfortable

  • Perfect density- very comfortable.
Color: Gel Foam + Mattress Cover Size: Bunk (30" x 72")
This size mattress fits my oakworks massage table top perfectly. I use the mattress on the table at the lowest height setting for guest sleeping- mostly youngsters. I also use it for working on people who have had surgery or for whatever reason cannot lie prone. Sidelying work on a hard surface is tough on the hips and shoulders- this mattress allows the client to relax and is still firm enough for me to work on the back. ... show more

  • Comfortable Mattress
Color: Gel Foam + Mattress Cover Size: Bunk (48" x 72")
We ordered this mattress for a guest room sofa bed. As other people have commented, the mattress was very comfortable, albeit slightly on the firm side. My 65 year old sister came to visit for two weeks and slept on it every night. I was worried she might not be comfortable, but she said she had no problems with it whatsoever and slept very comfortably every night. I'm glad we bought this mattress. ... show more

  • It is very important to know the company.
Color: Gel Foam + Mattress Cover Size: Bunk (32" x 75")
My corner sofa is very low—my knees end up practically touching my stomach when I sit down. That’s why I bought this mattress pad. It worked out perfectly.

  • Already indentions.
Color: Gel Foam + Mattress Cover Size: Bunk (42" x 80")
Edit After only 4 months its already indented and not supportive anymore. Maybe I should have gotten thicker size idk. I just know Im tired of not sleeping and hurting. I ordered the 42x80 for my hospital bed. It shorter. So either my feet hang off or my pillows fall through. Very disappointed its hard enough finding a comfortable correct size mattress for this bed. I thought I had finally found it but no. 😢 ... show more

  • NOT 80” long!! 77” at most
Color: Gel Foam + Mattress Cover Size: Bunk (30" x 80")
Purchased the 30”X80” gel memory foam mattress for my Byer of Maine Heritage Cot. Cot is 30”X82” but you can’t find sheets to match that size and 30”X80” is a standard size for RV bunks. The mattress I received was only 77” at most in length. I measured it straight out of the box so it hadn’t fully expanded yet which might shorten the length once it’s reached it’s expanded capacity. I need the extra length because my cat and dog sleep at my feet when camping (yes my cat comes camping! She loves it). I’m bit disappointed about it not being the length stated. I’m debating returning it and reordering but what if they’re all just 77” long. At this point I might just go to a local RV store and buy something from them. The mattress does feel very soft/comfortable and would probably be nice to sleep on but since I’m undecided about returning it I have rolled it back up as best I can and am not using it. I wish seller’s would just put the actual measurements of the product in description. Maybe they sent me the wrong size accidentally. The fact that it’s the incorrect size and it’s a cumbersome item to pack up and return I’m giving it 3 stars. If it was the actual size it says it’s supposed to be I’d probably give it 5 stars. So if you need a mattress that’s 77”X30” then it’s perfect for you. ... show more
