Our GOLD quality sofa replacement mattress has a foam density of 1.8 lbs. per cu. ft., which ensures you that you won’t feel the bar, while keeping cost to a minimum. The cover of this sofa mattress is sewn with a tape edge, reducing annoying cover shift from repetitive folding. Our Gold model mattress is available in 4-inch and 5-inch thicknesses in a multitude of common and custom sizes.

You’re going to like the sleep you get on this new sofa bed mattress. The foam is of a quality that other stores likely do not carry, and it’s probably much better than the sofa mattress that came with your sofa bed.

You and your guests will no longer dread the idea of sleeping on a sofa bed and “feeling the bar.” Your “Gold” quality couch mattress can stay crushed inside the sofa bed for years, and will spring back like new, whenever you need it.

    Hi Lou,

    I don’t like to leave reviews online, but I wanted to thank you for all your help with the measurements for the replacement mattress. I was so worried it wasn’t going to fit, but it fit perfectly, and as promised, I can’t feel the bar. Thanks so much.

    A Very Satisfied Customer

    We have been searching for a mattress for our full size sofa couch that would not have springs in it. After purchasing a previous mattress and then returning, we purchased from Replacement Mattress, it was easy with the diagrams on how to measure and shipped within days. Everything was a great experience with this company. Had to call them to answers some basic questions and they answered the phone and were happy to assist! Glad we found you! And made in the USA!! Bravo

  3. Tammy Wade (verified owner)

    Just want to let you know that mattress is perfect! And incredibly comfortable! So glad I found you on the web and that we chose to order from you. Many thanks for the excellent customer service and product!

  4. Peggy Tingle (verified owner)

    Fits Lazy sofa over 20 years old and sleeps fairly well for a sleeper sofa.

  5. C. Griffin

    Although you don’t feel the bar, the mattress is too hard for my guests. I had to buy a mattress topper (another $130) and find a place to store it. The workmanship and service were great, and I appreciate the constraints you’re working with, but I’m still disappointed.


      Thank you for your feedback Camden, we’re sorry you’re disappointed with the hardness of the mattress. We appreciate that you understand the constraints of manufacturing a sofa bed mattress that guarantees that you won’t feel the bar (if we would lower the compression of the foam, the mattress would have a softer feel, but it would be more likely to bottom out, and the sleeper would be more likely to feel the bar). Also, we offer the most mattress support possible given that you only have 4″ in depth for the mattress to hold up the body and it also has to bounce back from use and from being folded into the mechanism. That being said, when squeezing the Platinum vs. the Gold, the Gold will have a stiffer feel to the hand because of the lower density and higher compression. When a person distributes their weight, lying down, both mattresses will be on the harder, firmer feeling side, but the Gold may feel slightly stiffer.

    Excellent product, prompt shipping. Will use this company when looking for memory foam mattress.


      We’re glad we could help Philip. Let us know if you have any questions about our memory foam mattress options.

    I received the two, made to measure sofa bed mattresses I ordered a couple of days ago. I was extremely pleased with David’s help in ordering the proper mattress, as well as the ones I received. Not to mention they arrived a couple of days earlier than expected. Nice to know that there is a quality company selling on line.

  8. Eradio Arredondo

    Very helpful. Thorough
    Easy to order, for anyone.

  9. Steve

    I needed to replace my sleeper sofa mattress and was having a had time figuring out what and where to buy. The folks at Replacement Mattress were very helpful and we ordered our costume size mattress and it is great.

  10. Dale Halifax

    The information on products (emphasis on measuring our existing mattress and sofa) was much appreciated. The mattress was at our door quickly and fit our sofa perfectly. We could not feel any frame ‘bars’ with the new mattress and are certain our grandkids will sleep comfortably on the sofa bed. My wife made a few telephone calls with questions, and those calls were returned promptly and courteously. Great company.

  11. Linda

    Service was wonderful, I even received a phone call double checking the size and order! I needed an odd size and the mattress fits perfectly. Very firm and comfortable. I am very pleased.

  12. Terry Wyatt

    I had an odd size mattress in my camper that needed to be replaced. After striking out with local retailers and searching many websites, we found They custom made the right size for us, shipped it quickly, and it fits perfectly. It is much nicer than the original one we had. Lou even helped me with a special shipping request. Thanks!


    So happy to have found this company. Mattress ( 4 inch) fits my old 1960 ‘s sofa bed perfectly. My guests reported that is was very comfortable. Service was uncomplicated and no pressure at all. Super prompt delivery, too!

  14. Joan

    Very happy with customer service and the mattress is excellent

  15. Gary

    Customer service was excellent; was very patient and helpful in determining
    the correct mattress size for my sofa. (I didn’t think of looking at the tag on the old one). My guest (brother) had the best sleep he ever had from the sofa bed.

  16. Kerry Brandin

    Everything about the custom mattresses I ordered exceeded expectations. The price was much better than the competition, delivery was faster than I feared, and my guests reported a very comfortable night’s rest.

  17. Lisa

    Needed a replacement and the company is based in my backyard (NJ) Happy to support local businesses.

  18. Edward

    Have just ordered the mattress and looking forward to trying it out. Apparently only Pay Pay is accepted


      We’re excited to tell you that we just launched a new version of the site. Now apart from PayPal we also accept major credit and debit cards directly on our site (Visa, American Express, MasterCard, Discover, etc.).

  19. Jacers

    I needed to replace 2 sofa mattresses.
    I first purchased the Platinum. Way to hard. I plan on having my 250 pounder nephew sleep on it to soften it up!
    I then ordered the Gold which is much better.

  20. Nancy

    Received promptly-had to figure out how to best fold it-but once that was done it has been wonderful. My nephew slept sound and comfortable. Thanks, again.

  21. Sandy Ulf

    5 stars. Great website. Great service. Fits perfect. Comfortable no odor. Wonderful to work with. Thank you

  22. Gwen

    Easy ordering, arrived on time as promised, and a great product. Definately do not feel the bar!

  23. Dave Ketler

    Looks good. Can’t wait to receive.

  24. Karen

    I definitely don’t feel the bar but the mattress is rock hard . We already had a thick mattress pad so I need that in order to sleep on it.


      Given the mattress thickness constraints due to folding a mattress to fit a sofa bed mechanism, our goals are:
      1. Offer the best support possible in our sofa bed mattresses – this is achieved by using high density, high resiliency foam cores. 100% solid core support foam, no laminates.
      2. Eliminate the feel of the bar and or mechanism- this is achieved by using high compression foam core so that when you lay down on the mattress it won’t fully compress.
      Because we use high compression and high density foams, our mattresses have a firmer feel by design.

  25. Virginia Bisharat

    I was thrilled to be able to order a custom-sized mattress for the couch bed I inherited from my grandmother, because it’s huge – much bigger than all the standard sizes! We have a lot of guests stay over and everyone is impressed with how comfortable it is. The website is easy to use, and the mattress arrived promptly. I feel really good buying an American Made product as well. Thank you Replacement Mattress!

  26. Carol Bain

    Customer service was excellent; shipped promptly as promised. My daughter is very happy to have a comfortable mattress to sleep on when she visits, instead of the ‘cruel & unusual punishment’ of sleeping on the old worn out one. It even inspired her to purchase one for her sofa bed, so guests (including us) can sleep better. 🙂

  27. Betty J. White

    I was very impressed with the service; and the description of the
    product and the way it was shipped. It fits in my hide-a-bed perfectly.
