  • Great mattress
Size: 12 Inch Queen Black
I thought this mattress was going to suck because of the low price, but I am very pleased with it so far! It took about a week for my body to adjust to this mattress after sleeping on a too soft memory foam one for years. Honestly I love it. Its comfortable, just the right firmness and I can get up now without doing the turtle roll to get out of bed! Definitely recommend. ... show more

  • I have had mattress for about a month
Fantastic mattress I am a broke bitch construction worker needed something quick and cost efficient. Honestly, I’m pretty picky. This is extremely comfortable. I thought I wanted something more firm but this thing is perfect. It is actually soft, but not too soft.

  • Perfect blend of plush, and support!
Size: 14Inch Queen (Medium Plush)
I researched and looked at several mattresses both traditional mattresses, and other “bed-in-boxes” mattresses before ordering this one. I ordered the 14-inch black mattress and I LOVE IT! So comfortable with the perfect balance of soft & firm. It feels “plushy” while also giving me “firm support” in all the right places. My only regret is that I didn’t order this sooner! Love it❤️ ... show more
