FOR MY PURPOSE OF PURCHASINGTo start with! I had Abdominal & Back Surgery. Along with having Left Leg Sciatica and various other issues. I needed something to hold me up, keep me comfortable, and goodness to NOT WASTE MY MONEY!Followed the instructions. Let the pieces set up for 48 hours on flat surface. FOLLOW THE INSTRUCTIONS ITS WORTH IT!!!!!Ok PROS:•FOR my ABDOMINAL SURGERY, RECOVERY PROCESS it’s FABULOUS !• I LOVE I CAN ADJUST/ REARRANGE THE PIECES FOR COMFORT & TO REST MY SCIATIC LEG!• Value for the price point fantastic• Withholds it’s Structure• Material is SOFT• DOES NOT MOVE EASILY! Stays in place•I AM 5’8 200 lbs THIS HOLDS MY WEIGHT. THIS DOES NOT BUDGE or SINK IN. Love that.CONS:• For my BACK SURGERY the main BIG piece is way too FIRM, but I managed using the other pieces. THIS IS A PREFERENCE.• FOR SLEEP I use the smaller wedges to keep my everyday pillow up. The bigger piece is just too big and firm for me to sleep on for now.• FOR 36 hours this SMELLED AWFUL. I’m very sensitive to smells, BUT PER INSTRUCTIONS IT WILL GO AWAY! HANG IN THERE.• For Ease of Use ITS A LITTLE AWKWARD TO MOVE AROUND IF RECOVERING FROM SURGERIES. I RECOMMEND SOMEONE HELPING YOU TO SET THIS UP.This set is fabulous for really anything to do with Any kind of lounging like Beds, Couches, & even Floors! PLUS for CERTAIN SURGERIES, RECOVERIES, PROJECTS, SCHOOL, & READING.Overall I was shocked how well this product is made and withholds my weight. Even though the big MAIN piece doesn’t work for my back recovery for the moment, It will be wonderful to hold me up after I’m over that hump lolThank you thank you very happy!
