  • My Cat and I Both Approve 🐾
Color: Grey Item Thickness: 12 Inches Size: King (U.S. Standard)
I got the king size and absolutely love it. It’s spacious, supportive, and super comfortable — I’ve been sleeping so much better since switching. Even my cat is obsessed! He spends most of his day lounging on it like it’s his personal throne 😄 The mattress feels high-quality, stays in place even without a frame, and stays cool throughout the night. So glad I went with this one — highly recommend! ... show more

  • Right medium support for my back
Color: Grey Item Thickness: 8 Inches Size: Twin
I had a car accident a year ago that injured my neck and back, so proper mattress support is very important to me. I also tend to sweat a lot at night, so I need a bed that doesn’t sleep too hot. I’ve been using this mattress for over a week now, and it’s been perfect—it meets both of these needs. It’s cost-effective, the cover is of decent quality, and the feel is just right—not too firm, not too soft. I’ve been sleeping comfortably without any back pain. Overall, I’m very satisfied with this purchase. ... show more

  • Thin
Color: Grey Item Thickness: 6 Inches Size: King (U.S. Standard)
I wish it was thicker. If this mattress was 10" instead of 6, it would be much better. We use it as a mattress topper. It's comfortable enough and we let it air our for a full 3 days before sleeping on it. Which put us in the living room on an air mattress for 3 days. It was VERY disappointing when we finally were able to lie down and we were touching the platform. We ended up putting our old mattress back together and put this on top. I'm just thankful we kept the old mattress!! ... show more

  • Queen size mattress review
Color: Grey Item Thickness: 10 Inches Size: Queen (U.S. Standard)
Delivery was smooth, and setup was easy. The mattress expanded quickly. After couple of hours of opening, it rose up to 10 inches without any issues! But like the direction states, I will not be sleeping on it until 72 hrs for best results! It didn’t have any smell after opening the product and the product was packaged very nicely! It is very nice and as you see, my dogs love the bed as well! This mattress provides just the right amount of support and cushioning! Overall, I’m really happy with this purchase. It’s worth every penny for the comfort and better sleep quality. ... show more

  • More comfortable than expected
Color: Grey Item Thickness: 6 Inches Size: King (U.S. Standard)
This mattress was much more comfortable than I expected it to be. The cooling effect seemed to have an impact, but it could have been the placebo effect knowing that it advertised that technology. We slept well in our normal pajamas with our fan operating and the thermastat set at 70 degrees. Outdoor temperature overnight is in the 80's. We slept through the whole night and didn't feel warm or uncomfortable. The king size mattress is fantastic and an excellent price point compared to the brick and mortar stores in town. It take about 24 hours to fully expand and the corners didn't quite expand as quickly, but it eventually took shape. The mattress does come in a very tight, vacuumed sealed plastic bag and boxed up. This made it easy to bring in and out of the house. I have learned the thicker the mattress, the larger the box and thus the harder it is to move it from the front door to the bedroom. All of that said, it was a very quick and easy set up for a good night's sleep at an affordable price. ... show more

  • Very cozy and neat mattress
Color: Grey Item Thickness: 8 Inches Size: Full
I’ve been sleeping on this bed for several days. It doesn’t bother me, and got me deep and comfortable sleep mode. Its bed is a little heavier than I expected. But over all good quality. Clean finished and well made mattress.

  • let it rest for 2-3 days after unboxing
Color: Grey Item Thickness: 6 Inches Size: Full
This is my second try of a 6-inch mattress. Overall, I am impressed with this brand. I still believe a 6-inch mattress should not be used with a slat type frame, but that is a personal decision. Also, I still believe this is meant for either couple who are on the lighter side or a single individual no heavier then 225 pounds. This is the same as the other one I picked up, but with charcoal infused in the foam. As I stated with my other one 2-3 days of rest upon un-boxing this is an absolute necessity before you even use it. For better result you should shake the mattress to help the air get into the foam. If this step is not taken your mattress will fail prematurely. It breathes well and stays cool overnight which is very important to me. update: After some use, I can confidently say that this memory foam mattress continues to improve, providing increasingly better support and comfort as it molds to my body. Initially, it was quite plush and comforting, but over time, it has softened just enough to enhance pressure relief without losing its supportive integrity. The heat retention has decreased somewhat, making it cooler to sleep on, and the overall durability remains impressive, with no noticeable sagging or indentations. I appreciate how it seems to adapt with use, offering a personalized sleeping experience that gets better the longer I sleep on it. ... show more

  • Good Value
This foam mattress is a good value for the price, but it was disappointing in a couple ways. First of all, the mattress only expanded to 5 inches, even though we removed it from the box immediately upon receipt, and let it air out as instructed. Secondly, the listing implies that mattress is mostly memory foam. However, the attached consumer tag states that only 24% of the mattress is made of memory foam. As a result, the mattress is relatively soft to sleep on, more so than expected. For those who are curious about what exactly the mattress consists of, here is what we received: Two layers of foam, a thick one and a thin one, fused together and sealed in a cotton fabric inner lining. The thicker foam layer has the wave (airflow) profile carved into its top. The thinner foam layer, placed on top of the thick one, appears to be made of memory foam. The outer cover of the mattress consists of a soft, polyester jersey-knit material, with a zipper around the perimeter to allow its removal. The bottom of this outer cover is printed with plastic dots to provide a non-slip surface. The overall design and execution of this mattress is good quality; however, it is not exactly as described. ... show more
