Natural Dunlop Latex Topper Has Multiple Uses
Size: Twin XL 2"
This is a well made, high quality, 2” thick piece of all-natural latex. You can use it on top of any bed to provide a nice, comfortable mattress topper that has a medium-firm feel to it. It gives good support for those who sleep on their back and on their sides. The latex topper springs back and sleeps cooler than memory foam toppers, which compress and generally sleep hot. Latex toppers cost more upfront than memory foam toppers, but they can last twice as long. I built a custom-made all-natural latex bed that was too soft and didn’t provide enough support. I removed a 2” thick piece of ultra soft (#14) Talalay latex inside the bed and replaced it with this 2” thick piece of Dunlop latex for more support. I then used the Talalay latex on top as a mattress topper and now my bed is perfect! Once you’ve slept on all- natural latex, you’ll never want to go back to artificial memory foam.

Discovered latex and thrilled
Size: Queen
Bought a Beautyrest mattress in late 2021 that now is uncomfortable and has dips. Beautyrest would reject the 10 year warranty due to a single stain on mattress (based on their policy), so I didn't even bother. So, I pondered if I should order a new one and which one. In the process I found out latex toppers may save the day. Talatex medium firm mattress in queen size was received within a week and a half and installed on top of existing Beautyrest mattress. Since then, no pain in hips, no sweating at night, no neck problems. My daughter tested it one night with me, and since then wants to sleep on my bed and not hers, so this is really reviewed by two people. Excellent product!! Has a bounce but you don't sink in it (two mattresses ago, I had a 13" high end high density visco elastic memory foam mattress where sinking into it happened). When I can afford, I will buy a 4" latex topper firm and install that under the existing 2" Talatex medium firm over a slatted base. I'll do away completely w/ the mattress I'm using now.

Does not provide much pressure relief
Size: Queen
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.
