The Vispring Tiara Superb mattress has a luxurious softness evenly distributed throughout the mattress and with all the support to keep your body in perfect alignment. The high coil count and two-layer configuration provides exceptional conformability and resilience and the robust Shetland wool and long-stranded horsetail fibers create a super luxurious top layer from which you will get many years of comfort. Each of these materials work to wick away moisture and heat and will retain their shape and resiliency for as long as you own the mattress.
