    • First time getting a foam mattress, very impressed with it's quality
Style: 6" Size: Twin
Super comfortable foam mattress, medium firmness to me. Works great on the bunkbed!

    • Excellent Mattress!
Style: 10" Size: Full
Memory foam mattress is so comfortable. Purchased for grandson and wanted another one comparable to the Sleepys we purchased a few years ago, but this was less expensive, bigger mattress height, quicker delivery and better price. Do not need bedsprings.

    • Good for side sleepers
Style: 12" Size: Queen
It’s decent for the price but not the best for back support. It’s comfortable tho and works well for being a side sleeper . Purchased for our guest room so don’t have to sleep full time in it .

    • Just right
Style: 12" Size: Queen
Goldilocks here, wanting to share that this bed is finally “just right”. It’s soft and squishy and contours all those pressure points just perfectly. I’m happy- finally, after purchasing and getting rid of at least 3 beds in search of this. Price is a steal for how great I have been sleeping. Easy breezy to set up. No weird smells. I got the 12” plush queen. ... show more

    • Best purchase I've made this year
Style: 12" Size: Full
I was skeptical, not going to lie. I was even more skeptical after taking it out of the box. I unboxed it, left for work, and came back 13 hours later to see a huge mattress. Wow, Impressive! I waited another night to actually sleep on it and I LOVED it! I slept so sound and felt rested when I woke up. No smell, it kept me cool, and it's the perfect height. I've been deployed since that next day and literally cant wait to sleep in this again. Definitely worth the money! Highly recommended ... show more

    • Great ultra plush bed!
Style: 12" Size: Queen
I was extremely nervous to buy a mattress online without testing it out in person. I got the ultra plush bed. As soon as I opened it up, I laid down on it, and I know that you need to wait about 48 hours for it to fully inflate, but let me tell you I immediately took a nap on that bed. I have never been more comfortable. It's crazy because while laying in bed I can feel my spine being straight. Even though I'm lying on my side, I've never slept in a bed like that. It is very plush but not to the point where as soon as you sit down you sink and you can't get back up. You do sink a little bit, but it complements your body curves. It's been a really long time since I've been able to sleep this well. Update: I loved this mattress at first but the spring and summer time have been terrible. I literally wake up in a pool of my sweat everyday. I am never hot , and this bed makes sleeping terrible if it's warm out. I even bought multiple mattresses toppers that are cooling and they don't even do anything to help. ... show more
