  • Quality
Style: 12 Inch Size: Queen
Love it. Super comfy, a lot of support. It’s sturdy, and holds me good. I’m fat, 250 pounds, 5 ft.-5 inches and I don’t sink in. It was fully expanded at about 3 days after I unpackaged it. No defects, no smell. Nice and firm, but not “hard”. Best mattress I’ve ever had.

  • Queen mattress seems fine so far
Style: 12 Inch Size: Queen
Mattress seems fine, I didn't wait 48-72 hours and just set it up after I opened it. My old mattress was over 17 years old and have been pondering whether or not to replace it. The package is heavy so i had to drag it inside my house. I pulled the roll out of the box and used the included cutting tool to slice the plastic wrap. The mattress sprung to life. As I type this review, im laying on it, and it feels great. Highly recommended! ... show more

  • Pleasantly surprised
Style: 12 Inch Size: California King
After owning a temperpedic for the last 10 years, I was skeptical about a bed in a box. Times are tough and post christmas depression hit, so rather than dropping another 3k on a bed I gave it a shot. Best decision I've made! I've had 2 full nights of actual sleep!! Woke up with no back pain. It's the perfect amount of support and adjusts to any sleep position. I'm obsessed. Can't wait to come home and jump in bed. I ate in bed last night just to get more time on it lol. Great value for the price. Definitely need 2 people to lift and move. Also, when opening with the handy cutter they provide I suggest not standing directly in front of it. It pops open quick, which I'm sure was written somewhere and I was too excited to take note of. I didn't allow the 24 to 48 hours to fully expand because I have zero self control, but haven't noticed anything that has affected the quality. Don't hesitate or save it for later this is the one! ... show more

  • Comfortable!
Style: 12 Inch Size: Full
When my youngest daughter moved into her first apartment recently, she needed a bed. She chose this one, and I bought it for her. She loves it!

  • Do not purchase
Style: 12 Inch Size: California King
Do Not Buy! It is super soft, bouncy and not comfortable at all. My husband and I are pulled to the center of it, where we wake up multiple times a night on top of each other.
