It does keep you cooler/neutral. It needs to be a little denser. When you are on it, it goes pretty flat. It does help some but my hip needs a little more support that this offers. Be aware, the cover has a coating of fire retardant. We asked them to send one without the toxic chemicals. (Personal choice)

Forget about the memory foam!

Size: Twin 3 Inches

My sleep quality is fantastic on this thing, and I don’t even sweat like a memory foam cover! I was scared to spend the money but I’m glad I did! It’s really helped my back and overall pain, as it rises to fit the empty spaces left by flat firm mattresses.

Pretty Good

Size: Queen

The product arrived at my street address instead of my PO Box address last minute - without me getting prior notice that it was to large to be delivered to post office. Not sure why the seller did not notify me and let me know what was happening. The quality of the latex topper itself is good, covering nice with a zipper to take off and wash. There was no smell after about 5 minutes of coming out of the packaging. I am using it as extra padding for a new mattress which is pretty firm. After sleeping on it last night it helped just enough - perhaps someone who needs a little more cushioning should get the 3" topper version.

Soft and comfortable.

Size: King 3 Inches

The packaging was big and heavy and required 2 persons to move. The pad is soft and very comfortable. The latex had a bit of smell, but not too bad. Overall I am satisfied with the product.

Inaccurate

Size: Queen, Size: Queen

It was advertised as having an organic cotton cover, it came in a polyester cover. I thought because of the name “Talatex” that it was talalay latex, it is too firm to be talalay though. It’s a decent firm latex topper with a cover, but overall I feel it was deceptive inaccurate advertising.
