Man oh man finally a good mattress 😊 I cannot express how comfortable this mattress is. It’s not to soft and not to hard it’s just right! I got the king so plenty of room but you do need two people to move it it’s very heavy. It took about a full 24 hr to expand to its 12 inch. And 1 thing I will say is, my back been sleeping on so many messed up mattress’s that I’m sure my body had to get used to this quality mattress because I woke up with back pain for two days. But after those two days it’s like I’m sleeping on a cloud. It’s a win for a small price 👍🏼

I am 5'8" and 155lb. This is the perfect medium-firm and bouncy mattress. I have been sleeping on it for 1 year now and have had no issues. The mattress does soften a tiny bit over the first month of use but doesn't continue to do so. After 1 year of sleeping on this daily, I am not having any quality issues (no springs wearing through the mattress, foam sagging, indentations, etc). I will caution that it might feel too soft to someone 200lb+ looking for a medium-firm feel. To me, a true medium firm mattress should be comfortable for side/stomach sleeping. But I hate the feeling of not being able to move easily in the bed or feeling like I am sleeping in quicksand. This bed doesn't have that issue. The foam is springy and responsive. My body doesn't leave indentations that would make it hard to move. The motion isolation is quite nice, but not perfect. If two people are sleeping on the bed, you will feel a bit of jostling if the other person gets out of bed, but far less than with other mattresses at this price point. I tried out a lot of beds in stores but did not like any of them... The quality was not there. I would say that this bed feels like a $1,000 mattress. The only bed I tried that was more comfortable than this was the Purple hybrid mattress but that is $2k+. The firmness level is actually pretty similar to that. The bed is sturdy and well-made. It doesn't feel flimsy and is quite thick. The springs are stable and do not make noise. I can feel the springs a little bit when touching the sides of the mattress but it makes no difference to sleep. The springs are individual, so that helps with motion isolation. My sleep quality is amazing thanks to this bed.

The box was extremely heavy, of course it is a king size bed so, to be expected. Most of the reviews said it was of medium firmness, but I'm a bit disappointed it is as firm as it is. When you take it out of the vacuum seal it inflates to in amazing speed. I have slept fairly well on this mattress. No concerns with a funny smell to me or my partner. I did buy this on Amazon deal days so the price was great. The sides have a slight give to them when you sit on the edge but not anything I would complain about. Just wish it was a bit softer. Would highly recommend if you like a firm mattress for a decent price point.

When you are in a re-housing facility, you tend to get the plastic covered hospital “pads” that they loosely call mattresses. They may have started out as 6”, but after years you’re lucky at 3. Rules and regulations require flame retardant mattress. Very sore hips for side sleeper. Can feel every single metal slat, old pad springs weren’t poking through but you knew where they were. Plastic covered makes sense in certain settings but damn uncomfortable and noisy. Which lead to this purchase, and it’s a game changer!! My guy was going to go for the 8”, which would have been better than what he had but I said NOPE! Went for the 10” (top bunk, couldn’t go much higher lol). Yes, it is medium firm, in his case that’s a plus so he wasn’t sleeping on metal and feeling it. It provides the medium firm support but it’s still very soft. And he a freakin heater! Just hot all the time! While HAVING to have a fire retardant mattress and not liking fans (the feel of them blowing on him), while being directly under the heating vent due to bed assignments - this mattress is actually allowed by the facility for its fire/char/flame construction, doesn’t have chemical smell and it he doesn’t wake up drenched in sweat. For the price? HITS EVERY MARK NEEDED. For reference, he’s 6’1”, ~165 lbs. *did not wait more than probably an hour at best for this to “puff up” (bonehead) - didn’t negatively affect his comfort at ALL! I’d recommend doing as instructed - but saying if you don’t, and you’re a person that understands cost compared to product use compared to purchased need — this is a really great product - def recommend!

Love love love my new bed! As I said, it’s just as described. Firm but soft enough that it isn’t stiff. Actually has the isolated movement as suggested. Only thing I can “complain” about but not really is I got the 10 inch and probably should’ve gotten the 12 as this mattress is a little lower than my old one. Not a big deal but a noticeable difference. Great bed for the price, easy to read/understand instructions and super easy set up. Box is heavy. If moving upstairs, it would take at least two persons to move and lift, so keep that in mind.

There is a line down the center of the bed where it is not inflated completely even after 8+ days when you sleep on it you fall toward the center. Even with a 2 inch memory foam topper you slope to the middle. This is Saturday, I contacted customer support on Tuesday, I have heard nothing. Huge disappointment as someone with spinal issues I can't have a bed that slopes without massive pain. In the second photo I put a bedspread on it to show the area better.

I was skeptical about buying a mattress in a box, but this mattress is fantastic! It feels very supportive and comfortable. Not too hard, not too soft. Mattress inflated nicely and is true to size.
