Great chair for the price. Husband getting ready for a torn gluteus medius repaired, he will be non weight bearing on his right leg for several weeks. Not excited about the procedure but he’s feeling way better after the chair was setup and working. My sis has multiple medical issues regarding her back and knees, now she’s looking at purchasing one like ours, as she sees how happy we are with our purchase. Arrived one day later than expected, but no shipping damage! Overall very happy with this product. We still need to purchase an anti skid mat, as you can see from photo, temporarily using two smaller rugs for this.
