So comfortable!
I love this mattress, especially for the $$. I purchased the 12in Full size. It's super soft, but feels supportive. I have a bunch of issues with my spine and shoulders and have chronic pain due to those issues. Have a lot of issues with sleeping. Been thru 4 mattresses since January. This is my 5th and this is the winner. It's almost too comfortable. I can't say it has a "cooling effect" but unlike other mattresses I've had, I don't feel uncomfortable sleeping on this. Not kicking sheets and blankets off. I have no AC so it gets super hot in my house. I waited just over 48 hours to let in inflate before sleeping on it. It inflated to 10 ¹/2 at the seem but if you looking from its side, the actual mattress fluffed up to 12. Be careful with this... make sure the mattress is at angle that it will roll out away from you. My first time purchasing a bet that was compressed. POOF When it was on the floor there was minimal movement in the mattress. I sleep with a 65lb furbaby and he's always shifting positions. On the slatted frame now is a different story. So I advise making sure you have a strong sturdy frame. I feel like I kinda sink slightly into this. It's cozy. There's no pressure at my hips. Little bit at my shoulder. Little repositioning and no pressure anywhere. I do NOT feel the springs at all. No sounds from them either. There isn't really support on the sides so if you sit on the edge you will slip off. This was my 3rd night and I can honestly say I haven't slept this well in what feels like years! Usually I have trouble the 1st week or so getting used to a new mattress but this one.... I slept amazingly my first night and woke up with minimal pain. Overall is a great mattress at the price it's being offered. Expensive doesn't always mean better. I'm sleeping comfortably again so that's what matters.

Comfortable Hybrid Mattress with Excellent Support
I’ve purchased the LMANKBK 12-Inch Innerspring Hybrid Mattress twice—once for my kid’s apartment and again for my teen daughter’s room—and we’re very happy with both! The combination of gel memory foam and individually wrapped coils provides excellent pressure relief and just the right amount of medium-firm support. It’s comfortable, durable, and arrived well-packaged in a box, making setup easy. Highly recommend for anyone looking for a quality mattress that offers great value!

Not as firm as expected
We didn’t have 48 hrs to let it breathe, so maybe since my two year old doesn’t weight much it will continue to rise. It is MUCH less firm than expected. I wouldn’t consider it firm at all. But it’s still comfortable and will only be used by my toddler. So far so good.

Love this mattress!
Bought this for my 16 yr old daughter's bed and she absolutely LOVES it! It's incredibly soft but still sturdy enough for support. As someone who has severe back issues I can honestly say this mattress is wonderful. Definitely worth the money. It came to full thickness within a couple of hours and after having it for a month so far, I can say it's holding up perfectly well. You can sit on the edge of the mattress without it collapsing and you dont need a box spring at all. No complaints about this mattress at all! Will probably be buying one for my own bed soon!

Terrible
Don't buy, I can't believe the mattress I received is the same one that has so many good reviews. There is no padding to speak of, and the springs have no tension so you just sink into it, no real support and no comfort. I've been awake with a hurting back by 2am every time I've slept on it. I also ordered the 12 inch and it's far from that thick. Buyer beware across the board! I have returned it and had no issues with Amazon refunding me etc. But be prepared to call a live person and be transferred multiple times. Or save the trouble and don't buy it
