The MaxiComfort PR-505S is based on Golden's best selling Comforter PR-501 lift chair series. While keeping the same design, the MaxiComfort adds an infinite-position recline mechanism for enhanced positioning. Golden's infinite-position recline goes further back than the competitors', even allowing you to rest in a position where your feet are higher than your head to improve circulation. You'll also benefit from the 7-year pro-rated warranty and the option of three different chair sizes.
