It has saved my back. I'm a nurse and I was really suffering. I'm so thankful for this mattress! I'll never buy anything else from now on. It has a perfect firmness...just enough support with zero sagging in the middle like my previous mattress. I am so pleased with this purchase.

We have now had 5 Mattresses over a 16 year period. This is the best one. We purchased because it was firm and that is what we wanted. The price was VERY REASONABLE. Our sleep quality has improved greatly. Would recommend.

This mattress is nice overall. I can definitely understand why some would think it’s too firm, but I find it rather comfortable. It definitely forms to your body and has ample support. Ended up raising to just shy of 8 inches. I will say that after only having it a week or so I noticed that the gray cover had some spots where the threads were running and creating small holes. I also have to comment on the smell. It has taken literally two months for me to not notice the smell consistently anymore. I aired it out for 24 hours initially and then proceeded to unmake the bed and air it out for over another weeks time, and I could STILL smell it. Despite having all of the windows open and the ceiling fan on high every day for 10 hours. But I am happy with the comfort, and I did not find the price to be unreasonable.

Do Good Do More Do BetterReviewed in the United States on May 7, 2025

Great. Filled up within first hour. Filled to correct thickness of 8”. Firm, but not excessive. No odor detected. Have not actually tried sleeping on yet, but sat on and felt good. Would order again.

Got 10 of these to put on our bunk beds in our lodge. Would have broke the budget trying to do that at local shops. These mattresses come wildly compressed but are good to use in a days time. Not overwhelmingly smelly like some brands, definitely leaning towards the firm end of the spectrum but no complaints yet. Will definitely buy more when the time comes

Purchased this mattress for my 7 year old who needed a new mattress and she says it is so comfortable she is sleeping much better at night and not saying her mattress is hard. Once I unpackaged the mattress it took about 3 hrs for the mattress to come to its full size thickness. I ordered In a size twin XL and the size is very true.

Comfortable and supportive without being too firm or too soft. I’m really grateful I found this mattress. Super affordable, easy shipping and easy to unbox. Already purchased a second one for my son.

Good he'd, great pricing but a little firmer than expected. It does the job for my 4 year old and he hasn't started complaining. Took about 3-4 hours to fully expand.
