  • Great Price For Quality
Size: Queen Style: 12 Inch
The combination of the individually wrapped coils, foam layers and cotton bedding top provides the best buy for your money. It is soft and cushiony. I purchased two. I was able to get it delivered well packaged and with no rips or tears. They were clean and new.

  • Great Bed for a Great Price
Size: Full Style: 12 Inch
I am beyond impressed with the Serweet 12 Inch Memory Foam Hybrid Full Mattress. From the moment I laid down, I felt like I was sleeping on a cloud. The combination of memory foam and hybrid construction provides the perfect balance of support and comfort. I wake up feeling refreshed and rejuvenated every morning. Plus, the full size is perfect for me – not too big, not too small. The quality of materials is evident, and the mattress has held up beautifully over time. I highly recommend the Serweet mattress to anyone in search of a restful night's sleep. You won't be disappointed! ... show more

  • Great for the price
Size: Queen Style: 12 Inch
I love how comfortable this mattress is. I recently had such a horrible mattress and I upgraded to this and am so glad I did. My only gripes are that the edges of the bed are so soft that you can’t really sit on the edge, and that the mattress is a little unshapely on the corners. This mattress is so comfortable otherwise and I no longer have back pain. It’s still not firm enough for stomach sleeping because your back will cave and ache all day, but side and back sleeping it is perfect for. ... show more

  • Best sleep I've ever had, and well over double the energy level.
Size: Queen Style: 14 Inch
Very easy set-up, not extremely firm, but just right for myself. Only slept on it 2 nights, but my pain level is much lower, and my energy level is through the roof. Definitely the best purchase I've ever made.

  • The most comfortable mattress I've owned
Size: Full Style: 12 Inch
I bought this mattress to replace a broken down 16 year old mattress. It was easy to open the packaging. The mattress is firm yet so comfortable. I'm a side sleeper and used to wake up with my hip numb and my back sore. That is no longer the case with this mattress. I hope this brand sticks around awhile because I'll buy one again. I'm half tempted to buy another one just to have for when this one wears out. I highly recommend ... show more

  • Very comfortable
Size: Queen Style: 14 Inch
The media could not be loaded. This is a great mattress. It’s comfortable and nice and deep. It doesn’t need box springs. It arrived vacuum sealed in plastic packaging. After opening it, we waited two days to let it completely inflate before using it. It is nice and thick - we use deep sheets on it. And it is SO comfortable - not too firm, but also not so squishy that you sink in too much. It really is just right. We are very happy with it and think it’s a great value for the money. ... show more

  • Love this bed “queen”
Size: Queen Style: 12 Inch
This mattress is soft and firm. Definitely a quality purchase. For the price it’s a steal. I would definitely buy this bed again. It expanded and is like a cloud.

  • Too Firm and Uncomfortable
Size: King Style: 12 Inch
For being a foam mattress, this did not feel like it molded your body nor did it segregate movement. I could feel every move my husband made. We purchased the 12 inch king hybrid and gave it a good try for almost 3 months. Although it supports me as a stomach sleeper, it is way too firm for side sleeping. Inflated easily on arrival, no odor, cooling is effective, and appears to be made well, just unfortunately not a comfortable option for us. ... show more
