  • Mattress

    I was a little afraid when receiving the box. But after unwrapping the wrap off the mattress my concerns was not a concern anymore. The mattress is very comfortable to sleep on.

  • Nice mattress!

    Came so bundled up didn't think it would do the trick, but it did! Its not the top of the line, but if you don't use your sofa bed as a bed on a daily basis, it does just fine. We wanted it mostly to reshape the sofa when it IS folded up, since t was drooping... and it did! To sleep on you might want a little mattress pad... worth the price.
