The Organic Latex Mattress Topper is not only an upgrade to your mattress, it’s an upgrade to your sleep. 2 inches of GOLS-certified organic, synthetic-free Dunlop latex is wrapped in approximately 1/2 to 1 inch of GOTS-certified organic wool and hand-tufted to ensure long-lasting comfort. Soft Dunlop latex naturally conforms to the curves of your body, providing a luxurious night's rest and a supportive, restorative sleep. By hugging your body, GOLS-certified latex helps keep the spine straight, which can reduce tossing and turning, and alleviate aches and pains. Latex in this topper is rated 23-27 ILD. Surrounding the latex is a layer of fluffy GOTS-certified wool, a blend of eight breeds of sheep’s wool sourced from small farms in New Zealand. Wool's natural insulating properties will keep you cool in the summer and warm during winter, while its mildew and dust mite resistance will keep you healthy and safe. Topper is encased in GOTS-certified organic cotton sateen. All sizes approximately 3" thick.
