  • I'm 3 stacks.
Color: White Size: King Style: 12 IN
I weigh about 3 stacks. My husband weighs 2 stacks. I use this mattress more than him. I sleep on it for hours and it always puffs back up. I wish it were softer but hey the fact that it puffs back up every time makes me happy. The price is good. The bed is huge. This is my first king size bed. If you're on a serious budget and like your bed to be firm I recommend this mattress. I do not get hot in this matress. I sleep better than I did in my old spring mattress. It has relieved the back pain tremendously. Those spring mattresses are terrible! Anyway, it expanded fully. I let it expand for 3 days before I used it. The kids were dying to jump on it. They are always on bed and they say it's comfortable. ... show more

  • Good quality and good price.
Color: White Size: Twin Style: 12 IN
It is really comfortable mattress. You can feel the firmness to support you, you can also feel its softness of cozy. We bought this mattress about 2 months ago for our guestroom. All our guests slept on it told me they had a very good rest. Then we bought another one two weeks ago. This time they delivered a wrong product, we knew it's wrong because we bought one before. After file return, they replaced a right one quickly. ... show more

  • Would buy again.
Color: White Size: Queen Style: 10 IN
Love the mattress! I'm 240lbs and my husband is 320lbs and it is comfortable for both of us. Will need a good box spring. I got the medium firmness and my hips don't hurts sleeping on it for 2 months. A little bit heavy and large for me to move by myself when it's expanded. It took about 15 minutes to expand after opening the plastic. The cover is removable and can be washed. ... show more

  • good/6in/worth it!
Color: White Size: Queen Style: 6 IN
i would make a list of pros & cons pros - 1. very comfortable 2. great price & quality 3. it’s a bit too firm for my liking but overall still great to sleep on. cons - i regret not buying one of the thicker options. i bought the 6in QUEEN size one. i was a bit disappointed that the corners did not inflate all the way. that’s why i decided to -1 star from my review to summarize this, YES i would %100 buy this product again. BUT not in the 6in option. minimum 8 for my following description. if you are on the heavier side i recommend getting a 10 minimum or more as the sides seem too not fully inflate. for reference i am 5’10 & weigh about 160 pounds. & the 6in thickness is enough for me in terms of comfort & it’s just thick enough to where i can NOT feel my box spring or be uncomfortable. ... show more

  • The Most Baller
Color: White Size: Full Style: 8 IN
A little larger than i expected but that's on me for not paying close enough attention to the dimensions. The PERFECT firmness though!! Everyone who's slept on it has liked it quite a bit and commented on it being extremely comfortable. It stays cool and supports my body super well and was extremely easy to just roll out. I slept on it the same night it was unrolled and it was ready pretty much instantly. ... show more

  • 1 Year Update!!
Color: White Size: Queen Style: 12 IN
1 year update! So i ordered this 13 months ago and I will say that it id still holding up very well! I was searching for a long time for a mattress that had a good weight capacity and wouldn’t have sinking areas like my previous mattress. At first it was too firm for my liking and I almost sent it bacK BUT after a few months It felt alot better. Not too firm not too soft. Still comfy and the material is easy to clean😌doesn’t feel like it’s wearing out in any way so i hope it lasts a long time👍🏽 ... show more

  • Impressive mattress thoughtfully designed
Color: White Size: Twin Style: 5 IN
Five inch is one inch soft foam on one side and 3 and 3/4 inch firm foam on the other (measured with both covers removed). Arrives in a sturdy box, well protected - wrapped in about ten feet of 5mil plastic sheet wound around the vacuum sealed plastic bag. On removal from vac bag it gradually expands to full size evenly thruout. It has an outer cover of quilted polyester on top and sides and the bottom side fabric is a thin layer with very small rubber bumps one inch apart to resist sliding. Opening the bottom zipper the foam is encased in a stretch knit cottony sleeve - a separate inner cover, sewn tightly over the foam. Comfortable to sleep on; Thoughtfully made and wrapped; I am positively impressed by the packaging and construction and would purchase another from this manufacturer in the future, presuming it holds up to reasonable use. ... show more

  • Love this mattress....
Color: White Size: Twin Style: 5 IN
Mattress came in super-fast. The mattress inflated so fast and very well. It is extremely comfortable to lay or sit on. I bought this for my 3-year-old son, and he seem to like it very well. It is easy to move around in the bed and the height is great not to thin or not to thick just perfect. I love that it comes with a cover over the mattress to wash. It is not necessarily resistance as it will seep to the mattress but that's ok doesn't really affect the stars. Buy the mattress you won't regret! ... show more
