The Star medical mattress is a perfect combination of classic pocket springs and durable XFoam. Independently working pocket springs divide the surface into 7 firmness zones matching the anatomy of the body, so the spine is correctly aligned in every sleeping position. The springs are covered on both sides with a 5 cm layer of foam, which guarantees exceptional comfort and allows the mattress to be used on both sides. Recommended for people with back pain, muscle tension, discopathy, scoliosis or sciatica.
