Best for the price

Twin size very reliable comfortable fits on a twin size bed frame. You do not need a boxspring. It is very thick memory like phone worth your money is nothing to assemble fits. Perfect. Sleep quality. My son is four years old and he loves it. Doesn’t wake up, not one time and if it was ever mistakes, it’s easy to clean.

Out of pain

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.

Good overall

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.

Worth it!

I’m not sure why there are complaints in the reviews. This mattress was well worth the affordable price. It is firm, yet comfortable. I also purchased a topper to add some plushness for the perfect balance.

Best one we have had

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.

Great value

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

Very satisfied

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.
