Commonly referred to as a back stretcher and/or a neck stretcher, the present invention pertains to an apparatus designed to relax the users back muscles as gravity safely and smoothly decompresses his/her thoracic and lumbar vertebrae while lying chest side on the apparatus and same said apparatus being made reconfigurable to safely and smoothly decompress the users cervical vertebrae while lying back side on the apparatus. When configured to decompress the users thoracic and lumbar vertebrae, the apparatus is equipped with armrests or arm-harnesses to retain the user in place against the down-pull of gravity said armrests or arm- harnesses made adjustable to fit the users body length and chest width. Furthermore, the apparatus is equipped with a facial support with opening allowing the user to see through and perform other tasks while lying chest side on the apparatus said facial support made adjustable to fit the users facial physical features as well as his/her neck and head lengths. The apparatus is also made adjustable for distinct curvatures, allowing the user to emphasize the effect of the down-pull of gravity to act on his/her thoracic and/or lumbar vertebrae. The apparatus also comprises an abdomen surface adjustment enabling a user who has a medium size or a large size abdomen to obtain as close as possible to the ideal configuration for best spinal decompression geometry which provides enhanced blood circulation within the intervertebral fibrocartilage (discs) and other tissues between his/her vertebrae. The apparatus is also equipped with an adjustable shelf allowing the user to perform other task(s) while lying chest side on the apparatus. When configured to decompress the users cervical vertebrae, the apparatus comprises an adjustable head-harness to hold the users head in place while gravity smoothly pulls on the remainder of his/her body. The apparatus is also equipped with an ankle support and an extendable surface to deter the user from using his/
