"We got the Bear Trundle Mattress for our son's trundle bed a couple years ago, and it's held up so well. He's had sleepovers, naps, even some roughhousing on it and it’s still in great shape. It’s firm enough for support but soft enough that kids actually sleep through the night." — The Mattress Advisory Forum
