Our ACHE LESS™ mattress is a patented memory foam pillow-top/firm model. Designed around a heavy density visco elastic foam core for lumbar support with medium density visco elastic foam at the head and foot. Next the pillow-top is created from a 1 inch layer of low density visco elastic memory foam followed by quilted cotton and another 1 inch layer of low density visco elastic memory foam topped with a layer of antimicrobial fiber. Finally the fine damask cover is quilted to create a premium pillow-top/firm mattress. The mattress is paired with a matching box foundation.
