I purchased this mattress for my guest bedroom, and it has been a good choice so far. The 10-inch hybrid design offers a great balance of medium-firm support and comfort and the gel memory foam provides a cool sleeping surface. The setup was easy since it comes vacuum-sealed in a box, and it expanded to its full size in about two days. Overall, this mattress offers good value. I would recommend it for anyone looking for a versatile and affordable mattress.

OMG I really wasn’t expecting the bed to be as soft as it is. I also didn’t know that I liked soft beds but man I have been sleeping so good lately. My last bed just went weird and warped on me one day so finally I replaced it with this 12” mattress. I let it air out for about 56 hours since there was nothing listed I just let it sit for a little over two days. When I finally got on it I couldn’t believe how soft it was, I thought I was crawling across a large pillow. I have always had firm beds so I was scared that I was going to wake up with a sore back or something. Nope, I woke up so refreshed it was like the bed just cushioned around me. It was the first time I slept on my back in years. At times it feels hard to move around because of all the cushiness, especially when my two kids sleep with me but it is so comfortable it’s okay. There was no strong smell when I unwrapped it and it was nice that it came with a cutter for the plastic wrapped around the mattress. So far I would say it is a great value for the money, if you like soft beds, which apparently I do!

Wow! I just made a small hole in the plastic film, and it expanded surprisingly quickly, too fast, no need to wait, the workmanship is very fine, the fabric is very skin-friendly, very elastic, but not very soft, very satisfied, I can throw away my old mattress now.

nice mattress. It comformed to full 10 inches in thickness, very quickly. It's a medium firm so it it soft. I bought for the grandkids bed. My granddaughter is 14 and said it was very comfortable. It seems to be very durable, not sure about waterproof but I keep a waterproof mattress cover on it since it's for the kids.

I bought this mattress for my oldest son he’s28, 5"4 145lbs who has back problems and needs a firmer mattress. Being as it was the most affordable option at the time, $150 with $60 coupon I decided to take a chance. He has it on the floor for a base it’s holding up better than I thought it was going to. Been a couple weeks now and he is not easy on nothing. He’s very happy with the comfort of it no complaints. So, I decided to try it out, for the reviews sake. It was too firm for me. I’m used to sleeping on a pillow top. I’m 54 and 155lb. I could feel the springs through the side of the mattress just made me feel like it was cheap and I wouldn’t want it as my main bed mattress. I feel this matress best for a guestroom mattress or for someone who doesn’t weigh over 200 pounds. Sleepers who like a firm mattress. I think say this is a good affordable choice. It was super easy to set up. We did let it inflate for 24 hours and that was it. Very happy with the quality and the10 inch height is just fine. But I feel that the 12 inches would’ve been more substantial and probably a better quality mattress being as it would’ve had more layers I would think. Hope this review was helpful, thanks.

For the price , this is a good quality item. My daughter said that it is comfy and is just what she wanted. More soft, medium vs medium firm .

I took an honest leap of faith with this purchase but I’m happy I did . I was worried it wouldn’t fully expand or would be uncomfortable but it definitely expanded to the right size and is Super comfortable , it comes with a small box cutter thing to cut open plastic so look for it before struggling like I did ! It’s the perfect amount of soft and firm . Doesn’t sink or sag . Overall great quality for the price .

I love this mattress. It has enough support for the body. I don’t have any issues with sleeping after using it. But I’m not sure if it is memory foam on the top part. I put extra protector on it. I used it for one month already and it still looks like new. Nothing wrong with it. I recommend it.
