It’s a great mattress
Surprised it fit in such a small delivery box. Very nice queen mattress. I thought it was very comfy when I tried it out. The wife didn’t like the voc smell. Our guests said the bed was great, so no complaints there. Would definitely consider this for when we replace our own mattress.

Amazing bed for a side sleeper like me.
The vast mattress I’ve ever owned. Delivery was fast too. I was very nervous because I needed a good mattress and I will be buying another one for our guest room too. Do not hesitate with this purchase. Worth every dollar!

Happy with my first mattress in a box.
Seamless delivery, unpacking, and placing on base. Quality mattress and comfortable to sleep on for me. Hoped to get sleeping surface for wife (instead of recliner) who has badly arthritic shoulders (that did not work out, only recliner keeps pressure off her shoulders). If I needed another mattress this would be the one. Who would have thought a compressed mattress in a box would be so good.

Dont buy it. go to a store, test it out and buy one.
I research this and went with the reviews and said it was a good mattress. I’ve had it for a year and I bought the side sleeper mattress. It reminds me of mattresses you find when you’re sleeping in a cheap hotel. My back hurt constantly, and I did not sleep well on this at all. It has a squishy sound every time you turn around after pulling my back out twice with this mattress, I gave up and put my old mattress back on.

Too soft
Too soft for my taste personally. Quality seems good but expected it to be firmer.

Comfortable for back pain and side sleepers
We've had the same mattress for 20 years and it was time to get a new one. I did a lot of research and found that this one was the best for people with back problems and side sleepers. Took a few days to get used to but we are very happy with this purchase. Very comfortable and I wake up with a lot less back pain.
