1Twin size overlay waffle mattresses with out pump

I have 1 gently used waffle mattresses that I used on my bed for extra protection from getting bed sores. They work really well and are really beneficial for people who are in bedridden. They help protect your skin from too much pressure and help prevent breakdowns and bed sores. You can use a regular air pump to air it up, and it doesn't take very long. I would definitely recommend for anyone who spends a lot of time in bed. They really do help with pressure relief. I have one on my bed and have 1 extra. I'll take $10, or best offer. When online they run anywhere from between $30 to over $100. Which is crazy, there's no way I'd pay that much for an inflatable waffle mattress. The picture posted is exactly how it looks pumped up on a hospital bed like mine. But you can use it on any type of mattress.
