  • Great for kids!
Size: 10 Inch Twin
Purchased for my preteen's room. She absolutely loves this mattress and insists that it is more comfortable than our Tuft and Needle queen size mattress. Great buy, easy to unpack, expanded quickly. No noticeable smell upon boxing, but we did let it air out for 24 hours before putting it in her room. Soft, but still supportive. ... show more

  • Awesomeness

I purchased a King, One of the best mattresses Ive owned! Great quality! I let it sit for about 60 hours before laying on it. Just have to try it and see. I was skeptical bc im used to a firm mattress but this bed is very soft. I don’t have any back pain and I used to have back pain every morning. Great buy will def be buying in other sizes! ... show more

  • Best Sleep I’ve Had in Ages — Great Support & Comfort
Size: 12 Inch Queen
This mattress exceeded all expectations. It arrived tightly packed but expanded to full size within hours, with no lingering odor. The firmness is just right — supportive without feeling hard, and it helps with back alignment. I used to wake up stiff, but not anymore! At 170 lbs and 170 cm tall, I tend to move around a lot in my sleep. This mattress absorbs movement really well and keeps cool throughout the night. If you want hotel-style sleep on a budget, this is absolutely worth it. Firmness, doesnt small, the spleep quality a 100% i really loved this matress. Its heavy ... show more

Comfortable, still deciding if we need a 2 inch foam to make the bed appear more robust

  • No complaints
Size: 14 Inch Queen
This bed is nice! It’s very supportive, soft but firm, if that makes sense. I sleep like a baby, not much tossing and turning for me! Th corners did not expand all the way, but it’s really not an issue. I also couldn’t resist this bed for the whole 72 hours (I’ve been on an air mattress for two months), but I did allow 48 and it plumped up fully (minus the corners, but not a big deal - they look fine)! It was rather heavy to get up a flight of stairs solo, but where there’s a will there’s a way! The blade that came with it was very helpful and efficient. There was a slight odor to it, but give it a few days and it leaves. No complaints thus far and it’s been about a month! ... show more

  • Very comfortable
Size: 12 Inch Queen
Please beware of the package labeling 'caution' it will burst open. I just unpacked this mattress today. And I was concerned because of buying on-line. This mattress is so comfortable! And I don't know what the reviews were staing that they can feel the coils and they squeak. That is not the case here. Cause I did not feel not one coil. The top is soft but the rest of the mattress makes up in the firmness. It is still expanding and needs another inch ht. So I'm going to leave it out for 2-3 days before using it. I bought only one, just to see how it was. Now I will purchase the 2nd one. Best mattress I have ever gotten for my 2 guess rooms and the price is awesome. ... show more
