I have two massage chairs: a portal pro and a Healthmark. I volunteer once a week at the Ronald McDonald House and so I leave the Healthmark there. It collaspses fairly easily but the chest cushion doesn't move which can make it uncomfortable for pregnant women. I have the Portal Pro in my offive for clients and free chair massages. I bought during school through their supply store and received free shipping to the school. It was expensive, but the chest cushion can be moved and it collaspes quite flay.
