I was a bit hesitant to buy this mattress since I’ve had more expensive hybrids before, but after moving into a new place without furniture, I needed something fast. I’m so glad I gave it a shot! This mattress is an amazing deal. It comes rolled up, compressed, and packed in a small box. It’s heavy, so when you unbox it and cut through the plastic, watching it expand with air is actually kind of fun. The mattress has coils and springs with just the right amount of soft fabric on top. It’s firm but comfortable, and at just affordable price, it was a way easier option than going to a big store for a Full mattress. Once I unwrapped it, it inflated quickly and was firmer than I expected. I let it sit for about 12 hours before sleeping on it, but ended up adding a 3-inch foam topper because it was still pretty firm. I went with the medium-firm option, and although it’s a little tough at first, I’m sure I’ll get used to it. The quality seems great, and I’m confident it’ll last for years. My back already feels better than with my old mattress, so that’s a win. Overall, I’m really pleased with this purchase and wish I’d done it sooner. The setup was super easy, and there was no chemical smell or off-gassing. I got the 14-inch King, and it’s true to size. The medium firmness is perfect and gives great support. Plus, I love the grey cover—it looks better than other options. I highly recommend this mattress if you’re looking for something solid at an unbeatable price!

This mattress is incredibly comfortable and supportive. The medium-firm feel is perfect for my back and provides great lumbar support. I noticed a big improvement in my sleep quality, and it’s cool and breathable all night. The packaging made it easy to set up, and there’s no fiberglass, which gives me peace of mind. Excellent quality for the price!

I’m really happy with this mattress! It’s eavy but one person can lift it.It has the perfect balance between firmness and comfort. The memory foam adjusts to my body while the springs give strong support for my back and lower back. Since I started sleeping on it, I wake up without pain. It doesn’t trap heat, has no bad smell, and the quality of the fabric is great. Definitely worth every penny.

Out of the box to setup was very easy and fast, just unroll and cut the plastic and it immediately started filling up with air. The mattress seems sturdy, with the top material thick and soft, so the springs underneath support you,without being uncomfortable. Easy to wipe down if you have a small spill. It has a very elegant look and is very comfortable to sleep on.

Very comfortable. Soft material and great memory foam. Smells like a brand new mattress when opening. Easy to open up and put on bed frame. Is light weight and expanded with a few minutes of opening up. I have had the best nights sleep since I've received them. Live how white it. Is

This mattress is not medium firm, it is incredibly soft and minimally supportive. No weird smells or anything, it looks fine, but I'm waking up with back pain for the first time in my life, as an average weight male.

Just got this mattress today and I’m already impressed. It arrived well-packaged in a compact box and was easy to set up – it started expanding right away and reached full size in just a few hours. The first time I laid down, it felt supportive yet comfortable, with that nice medium-firm balance I was hoping for. Even after a short nap, I could feel the difference in how my back and shoulders were supported. No chemical smell, and the fabric feels nice and breathable. If it continues to feel this good after a few nights, I’ll be even happier. So far, it’s looking like a great choice!

I bought this mattress for my son and he loved it. It’s very comfortable, with medium firmness that’s perfect for a good night’s sleep. He noticed the back support from the first night. Great quality and excellent price. Totally recommended.
