Not too heavy to move from the porch into my sons room. And It was easy to remove from the plastic. I think my son will appreciate his new mattress as soon as it inflates.. Dayana. Spartanburg, SC. Sun Jun 01 2025

Bought this mattress for my son’s new bed, and he loves it. It expanded quickly, had no strong odor, and feels cool and comfortable to sleep on. He said it’s way better than his old mattress. It’s supportive without being too firm — perfect for a teen. Great quality for the price and I’d definitely recommend it for a kid’s or guest room.. Anonymous. Thu Apr 24 2025
