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.
