Our “Platinum” premium quality sofa bed replacement mattress is made with polyurethane foam with a density of 2.5 lbs. per 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.

When you sleep on a sofa bed with our Platinum mattress, you won’t believe how comfortable it is. In fact, 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-inch 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.
  • “What Bar?”—Our sofa bed mattresses won’t bottom out, even with 2 people weighing over 250 lbs. We’ve increased the compression in our Platinum model to create a firm, supportive feel. Even in a 4-inch thickness, it’s designed to hold up your body so you never feel 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 lb. 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 and are designed to last. We sew all the ticking seams and 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 inches up to a 65 inches 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—Certain full and queen sofa bed mattress sizes (52″x72″, 54″x72″ and 60″x72″) ship within 48 hours. Custom sizes ship within 4-8 business days.
  • 5-Year Warranty—We use quality materials and manufacturing techniques to ensure the Platinum model will remain firm and resilient for years to come.
