Customer Reviews


We purchased three of these stools for counter height seating. Our counter height is a low 35.5", so the adjustable height (both the back and seat) of this item made it a great fit. They are a great buy for the price and surprisingly comfortable. I initially had trouble with assembly due to a faulty leg - but a replacement part was swiftly shipped out to correct the issue.
