Been using the Kelburne Luxura a little over a week now. A good improvement over the old Staples Montessa II chair. Padding on the arms and seat are thicker on the Kelburne and the highest seat height setting is also about 1.5 inches higher than the old Montessa II. Seat is also large enough that you can sit cross legged indian style if you want (and if you're my size 5ft 8in 160lbs). Yep I would give the Kelburne a highly recommend.
I first went to the store and they were out of the color I wanted but shipped it to me within four days for free. Was simple and easy. And the chair is wonderful:)
