  • 10/10
Color: White High Density Only Size: Bunk (28" x 72")
Great measurements, fits perfect for my bunks. After reading a few comments I was a bit worried but once received very pleased. I’d say if you’re an adult looking for extra cushion double up (just stack them on top of one another) but they are great and lightweight as well.

Not bad for the price, definitely gets the job done, not intended for a full time bed, but for camping trips. Well worth it
