Hubby now sleeps cool and my joints are relieved. Owned an original Zinus many years ago and put them in the rooms of the small motel we owned. Ours got ruined in a hurricane and we went with another brand because back then we could get it faster. When that one wore out, tried a hybrid but was not for us. Went back to Zinus!

I had been shopping for a new mattress for a while, watching sales and reading reviews, when I came across this relative unknown ZINUS Nigh Therapy mattress at Sam's website. While there were only 50 some reviews, to my surprise there were none below 4 stars, so I decided to give it a try as it was also on sale for $100 off with free delivery. The box arrived a few days later, and I was surprised at how heavy it was. It weighs about the same as a regular mattress but it's all condensed into a box that is about the size of 2 King pillows atop each other. Anyway, I carefully opened it up and set it on my old box spring to allow it to unroll and "inflate". By that night, it was exactly as it looked online, just under 12 inches, but not by much, and by the way, no chemical smell--AT ALL! It took a night or two to really get used to the support which my spouse says feels very firm. I think it feels more like a hotel quality bed that forms to fit, allows movement without bouncing your partner out of bed and stays cool to the touch. After a week, I have to say that I am very impressed and sleeping through the night for the first time in a long time! Highly recommended, and if you can get it on sale that is a definite plus!

Great mattress for the price. I would say it's on the firmer side but still very comfortable. The last memory foam queen I bought from Sam's you kind of sink into it and had some effort rolling over but that does not happen here. And the fact it comes shipped to your door in a box is unbelievable. It was fully inflated out of the box in probably under 48 hours.

very easy setup. Mattress did take 3 days to fully expand. the zinus ulta cooling green tea memory foam mattress is comfortable.

10yrs ago we got the traditional greentea. Loved it. Last week we got the Ultra Cooling gel. True to advertising. Awesome for this 57 yr old menopause lady. Comfort A+ as well. Highly recommend

The middle of the mattress is okay but the edge lacks so much support that I fell off the bed the first night. I’m only on night 2 so hoping the edge firms up quite a bit. Otherwise, I will probably go through the hassle of returning this.

“A few days ago my mattress arrived. I still have two more days to use it (72 hours). I’m really excited to try it out — it looks great, definitely a good purchase!”

Very happy with my new mattress. Comfortable top memory foam layer, with good firm foam support below. Mild off-gassing smell for a few days, but not that bad. Seems to be resolved now. Overall, quite pleased

The mattress is good quality and nice material. Unfortunately it is just too soft for us. If you like to be cradled by your bed (which to lay on is lovely but a hard time sleeping) you will love this mattress. I wish it worked out for us.

I had a purple mattress for 10 years and i began having awful muscle strains and pain so heard about this bed so I bought it and it is the best bed I have ever owned. No more back pain and my husband says he no longer has his knee pain. We are learning in or middle age the importance of a good mattress and i promise if you are on the edge with this one...dont be..You will thank me for the referral.
