works but so uncomfortable to sleep in [SEP] i cannot deny that the results are pretty nice but this foam is so uncomfortable to sleep in it is like a stiffer pool noodle does not bend easilyi think it would have been better to fill it with stuffing then the styrofoam tube i will use this as a getting ready to go out for the evening kind of tool instead of an overnight one or i might take the tube out and fill it myself with stuffingthere also were not any instructions so had to base it off of other products
