Received chair approximately may 2017. Within a month, chair would stop going down from recline position. Selling company replaced controller, sill had same issue. Thought it was computer, so received new chair nov. 2017. In may 2018, started developing squeeking, needed front wheel assembly replaced. Front tires have chunks out of them. Now, chair no longer goes into full recline, with legs not raising above heart. Once legs reach as high as they will go (about half the incline he once had), the legs lose height. In my opinion, medicare should stop paying for this chair. It is supposed to last my husband 5 years, it has not even been 1 year.
