Magic Health Direct, Neck and Back Stretcher Board,

It is the sturdiest that you have ever tried--made with a high grade polymer, not plastic. It has a silicone base pad which keeps it from slipping. The padding on the top surface is more flexible and comfortable, and it does not have the plastic points the others have. It does take strength to assemble, but so did the others. Best of all, it is easily the most reasonably priced. it elongates the spine to reduce pressure and pain, providing the spinal decompression you need. Massager nodes gently massage your back to relieve tension and soreness. Note: Product is not intended to crack or pop your back, rather gently stretch. The higher the arch, the more of a stretch you receive. Ideal for sciatica pain and lower back pain relief. The back stretcher is designed to withhold a maximum of 350 pounds
