  • Right pleased!
Chose this mattress for a few key reasons: the 10-year warranty mentioned in the description, the very fair price considering the number of layers and individual coils (didn’t want something that was just plain memory foam), and the video showcasing someone who is actually heavyweight. That detail stood out, I haven’t seen that kind of representation on any other product listing on Amazon. This mattress was purchased for someone on the heavier side who really needs proper support. Straight out of the box, it felt great. I will update as time goes on. The layers are impressive, it has a soft, comfortable cushion on top, but a solid, firm base underneath. You don’t sink in, which is exactly what we were looking for. I’m surprised by some reviews saying it’s not firm, it definitely is. Yes, it had a bit of a new-product smell at first, but nothing unpleasant. I’m always cautious with big purchases, especially those that are a hassle to return if need be, but this one’s been a great choice so far. I may even buy a second one in the future. Will update as we see how it holds up over time in terms of support, functionality, and durability. Really appreciate that this company actually put care and quality into the design. Even the fabric itself feels high-quality to the touch. ... show more

  • great mattress for the price
I recently bought the mattress and I’m really happy with it. It’s a great mattress for the price very good quality without costing too much. The firmness is medium which is perfect for me. I don’t sink into it too much and it gives just the right support and my back pain has gone away which is a big plus. Another thing I like is that it doesn’t make any noise when I move around, unlike some other mattresses I’ve tried. Overall it’s very comfortable and a smart choice if you want a good night’s sleep without spending a lot. ... show more

  • Very Comfortable Mattress
I recently purchased this mattress and it has exceeded my expectations. The comfort level is perfect — soft enough to be cozy, but firm enough to provide proper support. Since switching to this mattress, I’ve been sleeping much deeper and waking up feeling rested. The quality of the materials feels premium, and the delivery was smooth and easy. I would highly recommend this mattress to anyone looking for better sleep quality. ... show more

  • Let it Breath. Comfortable
Arrived in a surprising small package with a cutting tool (letter opener). Packaging was light and easy to carry up my narrow stairs. After opening, the instructions say to let it breath and expand for a couple days - which it definitely needs. Shortly after opening, you can feel the springs, but after the foam expands for a couple days, the bed feels great. ... show more

Good value. Wish I would have gotten a thicker one, but this will work for a long while. Comfortable.
