I would definitely recommend this mattress. It is firm and very comfortable. I am very happy with the purchase and getting a good night sleep is worth the money. It doesn’t make noise and quite durable so far. My back pain isn’t an issue first thing in the morning.

I think this is a great mattress, especially for the money. When they say firm, they mean pretty darn firm. Topmost part is still slightly cushy. Edge support is good along with motion isolation (as long as they aren't really close to you when they're moving which makes sense on a firm bed. Build quality seems very good. Unfortunately a little too firm for me but I wanted to give a review anyway.

A little on the softer side of memory foam mattresses, still great! Was the exact size in the description. After sleeping there is a noticeable print but goes away after an hour or so and is not noticeable to feel when I go to sleep at night. Would def recommend waiting the FULL 48 hours for it to rise. Shape changed significantly to more firm and expanding in the last 8 hours. decent quality but would get during a time like black friday where you could get a discount. Not a bad Mattress other than I would have preferred it to be more firm. Noticed a Huge change in my posture and comfort waking up in the morning. Very breathable material and doesn’t get too hot and congested like some memory foam does.

Nice bed. Good quality and comfortable. One thing, be careful opening the bed from the plastic wrap. Make sure it unroll facing away from you

I bought this because the reviews were so high. Unfortunately, this mattress is like a rock. It just feels really cheap, which I understand given the price that I paid for it. It’s very firm unfortunately it’s just too firm for my liking. I really wanted to love this, but I will be returning it sadly. Next time I think I will just need to make sure I try things out in person before I can commit to buying something. That’s usually the best thing to do anyways is to try something out in person, but I will be arranging a return for this item. Update: slept on it WOW it’s horrible…I’m on so much pain after one night. Seriously, who reviewed this positively? This is the worst mattress I ever slept on. 0/5.
