Rated 5 out of 5 by Jeano41 warm to relax tight muscles
just two mins and it provides relaxing warmth to the back. it lays flat on the back so you can sit in a chair. took a min to figure out how to secure it. i put end through buckle and attached to fabric with the velco end. no instructions so i think that's how it works. probably fits a 46 inch waist. has allot of stretch. well made.
