Ruker water mattress provides excellent lumbar support
Excellent Lumbar Support
A too firm mattress cannot fit closely to the body. As lumbar lacking support, back pain would always be a trouble. While a too soft mattress though will fit perfectly with the body, with hip being the heaviest part, the spine would lose its neutral position. The concept of Ruker water mattress is that as you lay on the mattress the water shifts to accommodate your weight and shape, providing excellent lumbar support. Sleeping with proper support allow you to sleep in almost any position in comfort.
