Platinum Quality Sofa Bed Mattress

Our "Platinum" premium quality sofa bed replacement mattress is made with polyurethane foam with a density of 2.5 pounds/cu.ft., which is specifically designed for the heavier weight sleeper. Like our Gold mattress, the mattress cover of this item is sewn with a tape edge which virtually eliminates unwanted cover shift from folding and unfolding, again and again. Because of its density, this sofa replacement mattress is only available in a 4 inch thickness.

Using our Platinum mattress, your guests won't feel the bars of your sofa bed mechanism. We haven't yet found a sofa bed manufacturer, bedding shop, or other replacement mattress manufacturer that uses polyurethane foam that matches the quality of the foam we use in this mattress.

Sleeping on a sofa bed with our Platinum mattress will no longer be fearful, and you may even prefer it to your current bedroom mattress. This mattress can stay stored inside your hide a bed for quite some time without use, and will pop open as if it were brand new when it's needed.

  • Support – The majority of sofa bed mechanisms are made for a 4" mattress. Our Platinum model offers the best support available by using a 2.5 high density urethane foam core. This hide a bed mattress model is designed to hold up and support your body. Most of our competition uses 1.5 density support foams at best.
  • "Don't Feel the Bar!" – Our sofa bed mattresses won't bottom out, even with 2 people weighing over 250 pounds. We've increased the compression in our Platinum model to create a firm, supportive feel. Even in a 4" thickness, it's designed to hold up your body without the worry of feeling the sofa bed mechanism underneath.
  • Durability – We designed the Platinum couch mattress model to stand up to the rigors of the sofa bed mechanism, opening, closing and being folded up for long periods of time. Our high density foam core (2.5 pound density) has a high resilience, which will keep it coming back to its original shape for a long time. Our sofa bed mattresses are covered with the types of fabric (mattress ticking) that you would find on other mattresses in your house, design to last. We sew all the seams, it may take more time and be the old fashioned way, but it works. (We never use flimsy zippers that might break or make you feel uncomfortable).
  • Custom sizes – Sofa bed mechanisms come in a variety of sizes. We make hide a bed mattresses from 24" up to a 65" wide and in a variety of lengths. There is no added charge for this customization. Pricing is broken down by Twin, Full, Queen and Super Queen. If you don't see what you're looking for, give us a call, we'll try to help.
  • Fast Shipping – The most common sizes (52x72, 54x72and 60x72) ship within 48 hours. Custom sizes ship within 4-8 business days.

"Made whole" -
"We have this very old sleeper sofa that is still a beautiful piece of furniture but the coil spring mattress was in very bad shape. It had an odd shape and I didn't think we'd be able to get a new one. Enter Their website is one of the best organized and most informative sites out there. They are able to build a custom sized mattress and get it to you in a very reasonable time. They made our old, beautiful but unusable sofa sleeper whole again. Thanks guys."
"Comfort and firm" -
"I ordered the platinum mattress and it's very comfortable and firm as advertised. The mattress fit perfectly and Is used as my main bed. This mattress is better than the original sofa bed mattress for comfort."

"The 'kids' (thirty year old daughter and husband, both 6 foot tall) came in from out of town and used the brand new mattress. It got great reviews, they didn't feel the bar and it didn't collapse in the middle for the bowl effect!"

"I ordered a custom sized Platinum Sofa Bed Mattress. I was a bit concerned about delivery as I travel a bit so I called. Lou was able to tell me where my mattress was in production and when it would ship. It shipped on time and arrived a day early. This mattress turned a 40 year old Simmons hide-a-bed into better than new. I've tested it several times now as our condo is being remodeled, you don't feel the bars, I've slept great. The new mattress fits perfect, the sofa bed closes just right and now even the sofa is more comfortable to sit on. Thank you replacement-mattress! Jerry, La Jolla, CA"
"Great Custom Mattress and Great Price and Service to match" -
"I have a 20+ year old leather sofa/bed that was made of very very high quality materials back when things were incredibly well made for a higher price. The sofa looks almost as good as the day my grandparents got it and I didn't see any reason to give it up when the mattress finally came to its end. Thanks to REPLACEMENT MATTRESS for a great quality product. Ordering was a breeze and they shipped in a very timely manner!!!"

ReplacementMattress: Thank you for you kind words, Diana. Enjoy!

"Outstanding Products & Service!" -
"I am thrilled to be able to tell anyone interested in your replacement mattress products that this was the best decision I made for our sleep sofas. My husband and I purchased a new camp and the previous owner left us a great sleep loveseat and sofa. However, the mattresses we horrible. I researched and came across this website and ordered 2 Platinum mattresses. 1 was a standard queen size and the other a customer size for the loveseat sleeper. Expecting 2 -3 weeks for delivery, I was shocked when they arrived within a week!! And then to find the quality to be so superior to anything I could find in my research was just the icing on the cake. My 6' 6" / 200lb. niece's boyfriend said "I slept like a baby!" We will have these mattresses for many years! Thank you for your great Products & Service and for being Made in the USA!! -"

ReplacementMattress: Thank you for ordering and for taking the time to write the review, Karen!

"Sofa bed mattress replacement" -
"We hadn't realized how awful our old sofa bed mattress had become until some friends showed up with an inflatable bed to use during their visit. After doing some research, we chose to buy a Platinum 4" mattress from Replacement-Mattress to replace the old one. The measuring instructions were helpful, the ordering process was straightforward, and the mattress arrived promptly and in good condition. The next time our friends visited, they again brought their inflatable bed... but it never left the trunk of their car. I'll be back the next time I need a replacement."

ReplacementMattress: We're glad your guests enjoyed their stay, Karen, and we're glad we had a small part to play in that,. We hope many more of your friends will enjoy their sleep on the new sofa bed mattress.

"Gold and Platinum" -
"I needed to replace 2 sofa mattresses. I first purchased the Platinum. Way too 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."

ReplacementMattress: Thank you for your feedback Jacer. We're glad we could help in finding the right replacement mattress for you.

"Perfect Replacement" -
"The replacement mattress for my sleeping sofa was perfect. My grandchildren said it is very comfortable. It's good to know that they can have a comfortable sleep when they visit from out of town. The mattress arrived quickly, was packaged well, and was easy to put onto the sofa. It folded into the sofa with no problems."

ReplacementMattress: We're glad to hear your grandchildren find the mattress comfortable, Mabel. Thank you for taking the time to leave a review.

"I haven't bought a mattress yet but I can't find any reviews for the 4 inch"

ReplacementMattress: Thank you for turning to us with your question Lee. All the reviews on our Platinum sofa replacement mattress page are related to the 4 inch thick mattress, as we offer this type of hide a bed mattress only in 4 inch (the thickness of our Gold sofa mattress is available in both 4 and 5 inches). Hope this helps. Let us know if you have any other questions.

"sleeper sofa mattress" -
"We ordered this mattress for our queen sleeper from Haverty's. The old mattress was horrible as we could feel the springs. This new platinum foam mattress does not look that thick; however, it is comfortable and we are able to fold our queen sleeper easily. I'm glad we found this site and gave it a try. We will definitely keep you information for our next upgrade."

"mattress upgrade" -
"We recently purchased a 2000 class C Jayco motorhome. We have owned several motorhomes and campers over the years. This one had the absolutely worst bed we ever used. This torture device has a heavy steel frame with a supporting web of piano wire under a canvas tarp. The mattress was of the cheapest ... etc. We replaced it with the mattress from these folks and their claims are true. You don't feel the supports. Fit was perfect. We are very pleased!"
"great mattress" -
"mattress fits great. Staff very helpful in getting what we needed to fit an antique hide a bed. Would definitely recommend this company and would use it again."
"Dorothy" -
"Our platinum mattress turned out to be exactly as advertised. It is very firm, very comfortable. I also appreciated the information I received from this company; they spent a great deal of time with me over the phone, answering all my questions thoroughly. Our sleep sofa is an old one, so I wasn't quite sure if things would work out; they did! Highly recommend."
