So where to begin, we have been in search for over a year now for a replacement mattress that is firm but comfortable to help alleviate sciatic back aches. We have tried several brands ranging from expensive to avg price. All returned back because they either weren't firm as stated and didn't help with back aches. Finally decided to try this Queen mattress, after researching and reading reviews/videos etc... you name it! OMG, if you are in search for a true firm mattress this is it! I was hesitant because I never had heard of this brand and at a lower price range (on sale), but even at regular price it's truly great quality & value. Now after having it for a few months, I can happily say that my hubby no longer feels aches and we both feel rested in the mornings. Best part it had No odor, expanded rapidly, and we were able to sleep on it after waiting 24 hrs. We opened it in our living room area as we didn't think it would expand so rapidly but was pleasantly surprised that it did, see pics, and that was not even after 2 hrs. On a different note, it took me maybe 2 weeks to adjust since it's definitely firmmer than the mattresses I had in the past. The good thing is that adding a memory topper would help if necessary. So far, I am really happy with the purchase and glad I took the leap in getting it! The cover is made of high quality material has a zipper for easy washing. ... show more

    • Compact Delivery, Big Comfort and Support!
Size: Queen (U.S. Standard) Style: 10 Inch Pattern Name: Firm
I am extremely impressed with this memory foam mattress! It has the perfect firm support—just what I needed for a restful night’s sleep. The quality is outstanding: it feels sturdy yet comfortable, contouring to my body without feeling too soft. I’ve noticed less back discomfort since I started using it. Breathable and well-made materials, it doesn’t trap heat, so I stay cool all night. 😊 The mattress arrives in a compact box, maaking it easy to carry. Easy to set up, it inflates right away and holds its shape beautifully. Definitely worth every penny for anyone looking for a firm, supportive, and long-lasting mattress. ... show more

    • Sturdy, Easy to Use, and Great Support
Size: Twin Style: 8 Inch Pattern Name: Firm
I was pleasantly surprised by how comfortable this mattress is, especially for the price. It expanded well after opening and was very easy to set up. The firmness feels supportive without being too hard, and the gel memory foam gives it a nice cushioned feel. It sleeps cooler than I expected and works great for a child’s room, guest room, or everyday use. I also like that the cover is removable and fiberglass-free. Overall, this is a great twin mattress that feels well made and comfortable for a good night’s sleep. ... show more

    • Perfect for back pains
Size: Queen (U.S. Standard) Style: 12 Inch Pattern Name: Firm
I recently purchased this Firm Queen 12-Inch Memory Foam Mattress, and I’m very impressed with its quality and comfort. The mattress arrived quickly and was easy to set up right out of the box. It expanded to its full 12 inches within a few hours. The firmness level is perfect for anyone who needs extra support, especially for back pain relief. I’ve noticed a significant improvement in my sleep quality, and I wake up with less stiffness in my back. The gel foam layer keeps the mattress cool throughout the night, which is a big plus for me as a warm sleeper. ... show more

    • Very good mattress
Size: King (U.S. Standard) Style: 12 Inch Pattern Name: Firm
I had a Sleep Innovations for many years. A few in fact. I was setting up a new house. They don't seem to be around as much so I thought I would try this. Same price point. The mattress is very firm so far which I like. It had a slight odor to it when it was first opened. I let it breathe and opened a window. It did go away quickly. For the money it is a good mattress. Time will tell if it holds it firmness. Stitching is not perfect but that won't affect the sleeping. ... show more

    • Great mattress
Size: Queen (U.S. Standard) Style: 10 Inch Pattern Name: Firm
Honestly I didnt have super high hopes for this mattress because it was pretty cheap and that usually means not great. However this mattress has been a game changer for me. I've had back problems for years and lately its been worse and I new my bed was too soft. After switching to this my back pain has been very slight and not right when I wake up. I feel good getting out of bed now and im sleeping with way less pain than before. My shoulder hurts a little because im a side sleeper and it is very firm so I ordered a 3inch topper for it and now it's perfect! I highly recommend to anyone with lower back pain! ... show more
