The Happy Beds Signature Pillow Top 2000 Mattress offers a pillow top layer filled with natural wool and silk to give added comfort. The mattress is covered with high quality cotton-based damask fabric, carefully hand tufted for strength and durability. An additional pillow top layer, which is beautifully stitched, enhances the comfort to an advanced level. With the individually nested high-count pocket springs, you are sure to have a very relaxed sleep. The pocket springs work independently, to make sure that your body is equally supported in order to avoid unequal weight distribution when you move on the mattress. The Signature Pillow Top mattress has hand stitched side borders for edge support, carefully placed air-vents for breathability, and flag stitched side handles for easy rotation and handling.
