Add a layer of soft comfort to your bed! A 3" thick Twin topper featuring an organic cotton knit zippered outer around a Solid Extra Soft Natural Rubber Inner. The organic cotton knit zippered outer is machine wash and dry, the natural rubber is spot clean only. The 100% Natural dunlop proccessed rubber is the perfect layer for adding extra softness to your bed. It is also naturally bacterial and mold resistant too. This topper has a much softer feel than it's equivalent quilted top counterpart. This topper requires minimal care. Though not needed, for further ease of use it is recommended to use this topper in combination with a wool moisture pad, organic cotton quilted pad, or an organic cotton knit pad for liquid protection. Due to the organic cotton knit outer on this topper, nothing is needed to secure the topper onto the mattress as it will hold itself in place. Spot clean the rubber using 1 part natural cleaner or vinegar to 2 parts water. This item ships out within 5-7 business days and is made to order. Made here at our San Diego, CA Facility.
