Warnings and disclaimers

Disclaimer

Urethane foam will burn if exposed to an open flame or other sufficient heat source. Do not expose urethane foam to open flames or any other direct or indirect high temperature ignition sources such as burning operations, burning cigarettes, space heaters or naked lights. Once ignited, urethane foam will burn rapidly; releasing great heat and consuming oxygen at a high rate. In an enclosed space the resulting deficiency of oxygen will present a danger of suffocation to the occupants. Hazardous gases released by the burning foam can be incapacitating or fatal to human beings if inhaled in sufficient quantities. Once ignited, urethane foam is difficult to extinguish. Foam fires that appear to be extinguished may smolder and reignite. Always have fire officials determine whether a fire has been fully extinguished.

Very pleasantly surprised!

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...

Hard as a Rock!

Not sure how it has such good reviews. This is a very hard and uncomfortable mattress. The middle of the mattress is creased and it never fully inflated. Biggest regret and plan on replacing it soon. Invest on a better mattress is all I can say unless you like sleeping on concrete.

    Great mattress

    Bought this based on a prior purchase for a twin sized bed. This one is deeper and very comfortable. It’s on an adjustable frame and works well. I sleep really good with it in the 0 gravity position. It’s also very good for a side sleeper in the flat position.

    Excellent Mattress for the Price

    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.

    Ultra Cooling Green Tea memory foam

    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

    No edge support

    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.
