  • Overall a Good Purchase
Size: Queen Style: 12inch medium
After a little over a year of using this foam mattress, I can confidently say it’s one of the better purchases I've made! Initially, I was a bit skeptical about switching to memory foam and buying a mattress off Amazon, but this mattress has met my expectations. It has maintained its shape beautifully—no sagging or indentations, even after nightly use. Its recommended that one switches its orientation once a year to spread out the use. I will say that the support it provides is fantastic, especially for pressure points, and I wake up without the back or hip pain I used to experience. It took a couple weeks for me to fully adjust to the new mattress after I bought it. I looked online and found out that if you stand on the mattress and walk on it and do a bit of jumping, it helps smooth out the foam making it a bit lighter. After I did that, I felt better sleeping. I would say don't worry at first if it doesn't feel right, look online and find ways to make it better, and give it 2 weeks to sleep on it. One of the best things has been the temperature control; I was worried it might sleep too hot, but it’s been comfortable year-round. I also love how quiet it is—no creaks or sounds if I shift during the night. Overall, this mattress has offered excellent durability, comfort, and support, and I look forward to many more restful nights on it! ... show more

  • Comfortable
Size: Full Style: 8 Inch
I bought this for my guest room and my friend said it's super comfy. I love the foam hybrid mattresses and this one is no exception. Packaging was great and it fluffed up fully to size within a day. I left it for a few days before laying on it. It's the perfect amount of firm.

  • Comfortable and nice!
Size: Twin Style: 8 Inch
In just 5 minutes of opening, it was almost fully 8 inches and these pictures are pretty soon after opening it so the top 2 inches is still visible. The removable cover is smooth and the zipper works. It's really comfortable! Won't hesitate to buy another! Was skeptical of the quality but glad to have bought this brand! ... show more

Size: Full Style: 8 Inch
Best! Mattress I’ve ever owned! The 8” is perfect! Not too firm not too soft just enough to cradle you like a cloud, not too heavy, looks sleek and modern, not hot either. Best sleep, my husband, dog & I have ever had. No chemical smell, puffed up in 8hrs! Best money I’ve ever spent!
