Features

  • COMFORTABLE SUPPORT AND A GOOD SLEEP: The 12 inch king size mattress utilize a unique combination of individually pocketed springs and memory foam, which ensures that your weight is evenly distributed from head to toe, which relieves your body from contacting the pressure points of the mattress, and helps to eliminate your body's fatigue and aches and pains and it greatly improve your sleeping quality.
  • CERTIFIED SAFE MATERIAL: The king size memory foam mattress is made of high-density and first-rate temperature-sensitive material that is very comfortable and breathable, which drains out steamy sweat from your contact surface with the mattress and keeps you dry all night long. Your health is our top priority, so this king bed mattress is also CertiPUR-US certified and contains no fiberglass or other harmful substances.
  • ISOLATED MOTION: The matress is built with high-quality pocketed coils and slow-rebound foam, which effectively absorbs the noise and vibration caused by tossing and turning while you sleep, so your deep sleep is never disturbed by your partner's tossing and turning or getting up.
  • MATTRESS BED IN A BOX: The twin mattress will be compressed, vacuum sealed and neatly rolled in a box before shipping, not only is it easy to install, it is also smaller and more portable, this mattress fits all bed frames, you just need to measure the size. (Warm Tip: Package does not include bed frame)
  • BUY WITHOUT WORRIES: Please be sure to keep a safe distance as the best hybrid mattressmay expand quickly, and note that memory foam mattress takes 48-72 hours for the mattresses to be restored to its original state.

    • I can sleep
Size: Queen Style: 10 Inch
I knew this mattress was compressed, so I could put it in my travel trailer. packaging and delivery par for the course. cut plastic sleeve to unfurl open let it expand. I liked the plush feel on top and firmness.

    • Worth the money
Size: Queen Style: 10 Inch
I was not expecting too much given the price is too reasonable and this definitely exceeds my expectations. I wanted a new mattress because I am expecting and I have been experiencing a lot of pain from my back and my hip. This mattress is thick and supportive. I have been sleeping way better after getting this new mattress. I do want to point out that this mattress is quite heavy and would require two people to move. ... show more

    • Great for back/side sleeper with curvy body shape
Size: Queen Style: 12 Inch

I’m a back/side sleeper, and I have a curvy body, my hips are big while my waist is small…so I worry about my waist not being supported while I sleep. I’ve tried both pure spring mattresses and pure memory foam mattresses, but neither worked well for me. The memory foam mattress, in particular, often made me feel like I was sinking in too deep, providing softness but not enough support. So this time, I decided to try a hybrid mattress while it was on sale. After unboxing, it took me two to three days to regain its shape, and once expanded, it reached a thickness of 12 inches. It perfectly balances the firmness I wanted, which is medium firmness. The memory foam layer on top is comfortable, while the spring layer below provides great support for my waist and is quite bouncing. It doesn’t make noise and it’s shock absorption is surprisingly good as when I turn over, it hardly affects the person next to me. Buying a mattress online is risky, but I’m really glad this time I met the right choice. ... show more

Extremely comfortable and an amazing value compared to other mattresses I’ve had. Super easy to unpack and watch it re-inflate.

    • 0 out of 5. Would not even recommend to my worst enemy
Size: Queen Style: 14 Inch
Legitimately the worst bed I've ever tried to sleep on. We were desperate for a mattress due to moving sort of rapidly and not being able to take out our mattresses due to the amount of space. We have attempted to sleep on this garbage pile for twenty something days now and the quality of sleep started out terrible and consistently continues to deteriorate. This mattress is firm and yet somehow at the same time offers basically zero support for your back or lower lumbar. If you even look at the edge of the bed it basically starts to fold in and you start to roll off. After just this short couple of weeks the bed is already forming depressions where we sleep. It is extremely bouncy feeling in all the worst ways. The side of the bed offer zero support which is not good because we are used to a king mattress and this makes a queen feel even smaller when you have to stay 10 inches away from the edge of it. I'm seriously so disappointed we wasted $250.00 and now trying to process a return they say you have to put it into the original box like oh yeah let me just put this pile through my industrial mattress compressor machine and vacuum seal it back up into a little burrito. *Edit to my original review attempted to post. Still giving a terrible rating because the product is terrible. However Amazon did make it right and get us a refund and I donated the bed and went to the store and bought a new one and it's like sleeping on a cloud. ... show more
