This system consists of 3 pieces, a pillow, a wedge and a body pillow (memory foam). It’s also a size medium, which means it is good for anyone that is 5‘5“ to 5’11”. It can be used as a shoulder pain, relief system, used as an incline for acid reflux relief, for sleep apnea or it can also be used as a prenatal system as well. I used it for a shoulder injury but no longer have a need for it. The sale on their website for $320 but you can also find them at Walmart for $270. I’d like to sale it for $175 or best offer.
