Make a Massage Chair for Use of the Bedridden

 from Columbia, MD– Verified Buyer

I bought the chair for my daughter who is bedridden with MS. Unfortunately, it is very difficult to get her in the chair with the Hoya Lift because the back of the chair does not go down. I thought zero gravity meant that the chair would recline like a bed. Also, the chair would be more useful if there were a belt that would hold her in the chair. On the other hand, I enjoyed using the chair. But, why not make the chair suitable for the use of individuals like my daughter.

Heaven sent

 from MI– Verified Buyer

This chair was a gift to myself to have the convenience of a massage without going to the spa. The health benefits were an added gift that I hadn't planned on. The chair is beyond what I expected - looks good and is now a treat that I look for at the end of the day. Great quality, best investment that I have made yet - would recommend to everyone.
