We bought this mattress in 2021 and it's still comfy! Not overly soft or firm. We have no issues with loft or mis-shaping.

Did not fully expand in either end of the matress. It has been set up for 3 weeks. Would not recommend this mattress. We bought the full size mattess and platform. Will most likely have to replace the matress in the near future.

i have never gotten a memory foam mattress, but after laying on this one, BY FAR THE BEST! it is firm but soft once you lay on it! doesn’t require a box spring at all! i recommend to anyone, especially for the quality and price.

I expected this mattress to help with my back pain with a firm comfort but instead this turned out not making my shoulder blades stiff but worsening mower back pain.

Was great, but right around 3 years old my side has gotten very soft and I'm getting horrible back pain. About to try out the alleged 10 year warranty.

This mattress is barely one step removed from sleeping on cement. I haven’t slept through the night for 6 weeks since getting it, waking frequently in total pain. It’s so hard that laying on a wrinkle in the sheets or your shirt is excruciating. In fact, attempting to flop down on this mattress would likely cause a concussion. After 10-15 minutes of lying completely still and trying not to die, the memory foam will eventually conform around you, but then you cannot reposition without sleeping around a giant divot until it finally readjusts. I purchased the biggest, thickest mattress pad I could find to see if it helped but sadly, it did not. If you love to sleep on your sidewalk or garage floor, this mattress is definitely for you.

I want to throw it out now. I've only had it for 2 weeks. It is very uncomfortable. I cant sleep on it. I'm back on the couch. I have had the worse back pain, neck pain, and side pain. My granddaughter has made the same points. Never will by a mattress from Zinus Night Therapy again.

The FedEx guy left it outside of our fence on the driveway that's the only bad thing. The mattress is as it says 10 in king size mattress it only took a few hours to reach its full height but we left it for 48 hours. we haven't slept on it yet but it seems very comfortable and not too firm but not too soft. How long the mattress will remain comfortable and firm is yet to be seen.

This is the second one I’ve bought and they are great mattresses for the price. This one though is a few inches longer than a normal king bed. So it won’t sit in my bed frame. Was a little disappointed because it’s not something I can easily bring back or return.

I've had this mattress for 2yrs now and I agree with other reviewers, it's very firm for a memory foam mattress. I woke up with a sore back and shoulders when I sleep on this thing. I had to buy a topper to put on it, it's a little better but not much. Luckily my 4yr old sleeps on it and it doesn't bother him.
