What a relief!

I bought this chair for my father to gift to my mom. It arrived in two boxes on two different days, but it did arrive way before Christmas, so that was awesome! My father said that it was very easy to assemble and my mom loves how comfortable it is at soothing her sore muscles.

Extraordinary value and versitility

Every member of the family uses the chair every day. The zero gravity, heating, foot massage and bluetooth features by far exceed expectations. We'd recommend this unit to anyone.


Assembly was easy, chair looks solid, the foot massage is awesome, heating function works great, and provides excellent relief for lower back pain. Over all its really impressive.
