  • NO REGRETS!!!!
Color: Black Item Thickness: 14.0 Inches Size: King (U.S. Standard)
Ok!!!!! I SOOOOOOO wanted to dislike this mattress (because it was not delivered the next day as promised), BUT, I have not slept soooooooo well in years, as I have during the past week. It's sold as "MEDIUM" FIRM but to me, it "FIRM on STERIODS". It's a mattress in a box that has a suggested time to inflate to its full size, but it literally was 14" immediately out of the packaging, corners and all. And, did I mention, it is COMFORTABLE!!!!! I've gone from sleeping 3-5 hrs. each night to enjoying 6 hrs. or more and I don't want to get out of the comfortable bed. My back pains have minimized since I started sleeping on this mattress. Definitely a value for the money spent. I've already recommended this mattress to 3 other people and 1 has already purchased it. I'm literally a Proud, Walking advertisement for this product!!!!!! ... show more

  • Great price with comfort and support.

Fast delivery. I decided to replace my mom mattress and give her the one i purchased last year and take this for myself because it was black. It is very comfortable with great support. My cousin saw it and loved it so much he is purchasing one for his mom now to replace her current mattress. Great value for the money, quality is good and love the memory foam it has too ... show more

  • Wonderful
So let me explain what you're seeing in the photos. I have a sleigh bed frame with a box spring on the floor. There are no slats because I have such a deteriorating spine that there is no way that I can handle the slats that go under a mattress on a bed frame. Over the years I've experimented with many different ways to sleep and not wake up unable to walk. This is just one more experiment but I think it's going to take me at least through the next couple of years. So on top of the box spring is a queen size bunkie board and then a queen size box mattress bought in 2019. The bunky board was supposed to give me some support in between the box springs and the mattress. But because that queen mattress in a box is beginning to sag in the middle I'm starting to feel the bunkie boards just like I would feel slats in a bed frame. The only real answer is to go to the Sealy store and put down 5K on a really nice bed but since I'm living on a very strict budget and my purse is extremely light I decided to put another mattress on top of my mattress. So now I have a box spring, a bunky board, a queen size box mattress, and a full size box mattress that just arrived today. Boy is it heavy. I think it's heavier than the queen mattress that I got in 2019 from a box. Maybe my memory serves me wrong but I think this is heavy. I could hear my physical therapist shouting LIFT WITH YOUR LEGS! lol I opened it in the carport to get the box and the outer plastic off of it. I have no idea how I managed to drag it to my bedroom but I didn't open the inner plastic that seals it until it was on the bed. As soon as I sliced into the plastic the mattress expanded as they do. Use caution at this part because you could easily slice into your mattress. I let it sit for about 8 hours and air out before jumping on it. It's heavenly I got to tell you. This is better than my original suggestion of just throwing a mattress on the floor. And it doesn't have a weird smell at all. Now I'm literally like the princess and the pea. Because of all the chronic pain that I live in daily and sleep in nightly I really can feel every single bump underneath me so if I have to stack 10 mattresses on top of each other to get relief I will do that. I'm very happy with this full size mattress and since I'm the only one that sleeps in this bed there is plenty of room for me. Highly recommend! ... show more

  • Thumbs up
I’ve been sleeping on this medium firm mattress for a few weeks now, and I’m honestly impressed with how well it balances comfort and support. It has just enough firmness to keep my back properly aligned throughout the night, which has significantly reduced the morning stiffness I used to experience. At the same time, there’s a soft enough top layer that cushions pressure points without feeling too plush. What I really appreciate is how it accommodates different sleeping positions—I switch between side and back sleeping, and this mattress handles both beautifully. There’s minimal motion transfer too, so I’m not disturbed when my partner moves during the night. Overall, this mattress hits the sweet spot between too soft and too hard. If you’re looking for something that offers support without sacrificing comfort, I highly recommend giving this one a try! ... show more

  • Comfort plus
Kids sleeping better than me. It’s always a gamble buying bed in a bags because you never really know what you’re getting. This one is firmer than I’d like but made perfectly for the slat style bunk bed. We put at the bottom bunk because of height. Had a slight smell that disappeared after a while. Fluffed completely out by 3rd day. The quality is nice.,, comfortable to them but a little more firm that I’d like for myself. ... show more

  • NOPE….REFUND ASAP
Color: Black Item Thickness: 14.0 Inches Size: King (U.S. Standard)
This mattress actually fit a little higher than they measured it at very beautiful love the color does not smell like chemicals within about 10 seconds of opening it up you can lay on it. All of that is beautiful except the fact that it’s hard as a rock, I had to go get a 3 inch memory foam pad to put over this mattress and I literally tossed and turned all night and I don’t have back issues. I’m returning, asap, I’d rather pay $1000 for a comfortable than pay half that price and have back problems. Very uncomfortable ... show more
