    • Perfect Mattress
Size: Queen (U.S. Standard) Set name: 10 in
I’ve been sleeping on this Avenco 10-inch Queen Hybrid Mattress for a while now, and I’m extremely happy with it. It strikes the perfect balance between comfort and support—the medium-firm feel is just right for relieving pressure on my back and hips while still feeling cushioned. The gel memory foam helps keep me cool throughout the night, and the individually wrapped coils do a great job minimizing motion transfer. I barely notice when my partner moves, which has really improved my sleep quality. Setup was simple. It expanded quickly after unboxing, and there was very little odor. The mattress feels well-made, and knowing it’s CertiPUR-US certified gives me extra confidence in the materials. ... show more

    • Worth what you're going to pay.
Size: Queen Set name: 8 Inch
The mattress took almost no time at all to fully inflate and we had it on the frame same day. You can definitely tell it's only 8" thick but that's nothing a mattress topper can't fix. Beyond that, the mattress is SUPER comfortable and a good quality and price for what we received. It is a bit small in fitting the queen size frame I bought but that was expected when ordering a "kids" mattress. There was a little bit of an odor from factory, but it went away within 24hrs and wasn't overbearing at all. ... show more

    • Sleep as on mother arms
Size: Full Set name: 10 Inch
Sleep as on mother arms. The mattress expanded fully within about 2 days after unboxing and had only a slight odor that disappeared quickly. The combination of pocket coils and memory foam provides a nice balance between support and comfort. I primarily sleep on my side and back, and the mattress does a good job relieving pressure on my shoulders and hips while still supporting my lower back. One thing I noticed is that motion isolation is pretty good. My partner's movements don't disturb me nearly as much as they did on our old mattress. The edge support is also better than expected. The cooling feature seems to help somewhat. It doesn't feel cold, but I don't wake up overheating like I did on my previous all foam mattress. The medium firmness feels accurate comfortable without being too soft or too firm. ... show more

    • Horrible mattress but amazons return policy is awesome and convenient
Size: King (U.S. Standard) Set name: 12 in
I ordered a king. It was about 6 inches too short compared to the king I had and the one I just got to replace this one. The overall build quality of the bed seemed ok. The memory foam wasn’t very good as you can almost feel the springs. It was not at all comfortable for me or my wife (I’m 200Lbs and she’s 120Lbs). We both had the same issues with it as far as the feeling the springs and bot feeling rested after a night of sleep. Plus the added bit of back pain. I am a very heavy sleeper and she is a very light sleeper. She told me every single time I moved in the bed, I woke her up because the whole bed moved. We were coming from a memory foam mattress and wanted to try a hybrid. This was NOT, AT ALL a good move. This bed is very uncomfortable considering we like and are used to memory foam mattresses. It really doesn’t provide good support in our opinion. We returned it an got another memory foam mattresses and have been VERY happy with it. If you are coming from a memory foam mattress, do not buy a hybrid mattress. Stick with memory foam as this type of mattress is going to be a huge disappointment. On another note, Amazon’s return policy is excellent. Since this bed is sold and shipped by Amazon, the return is super convenient. They send a truck to your house during a scheduled time window and they take the mattress from you and that’s that. Kudos to Amazon for making the return process completely painless. ... show more

My first time purchasing a mattress in a box and I am very impressed! Mattress took no time to expand to its size. I didn’t smell any weird odors as other comments state, and am overall very happy with this purchase. Very soft and comfy and I believe this will be perfect for my toddlers room. It’s just the right amount of soft but firm so I can sneak out without waking my toddler up. ... show more

I received a twin that is about an inch too short. It’s otherwise a very comfy bed. I am very disappointed because I liked it and wanted to keep it! I was refunded and purchased something else
