Great lumbar support pillow, best design with washable fabric and looks elegant I have a throughout review of your product and compare with 3 others companies. Noticed that the differences of your product is the temperature control (when weather is cold, will be firmer. when weather is warmth, will be softer according to your product specification) and the material. The cover of the lumbar support pillow is easy to maintain, breathable material in the middle section covering large part of the back area; and the side of the lumbar pillow is using velvet which looks elegant. Quite firm in supporting the back area but not hard like a solid rock which is important.
