Worth $340.00? Absolutely not! I've never bought such a poorly designed chair and I won't be buying another from Inbox Zero again because of it. For starters, it came damaged with two scratches on the arms and one of the screw holes was stripped entirely. (see photos) Zero lumbar support. In fact, if you want any back support at all you'll feel like you're lying back. The massage and heat features are beyond weak and the padding on the seat overall is an absolute joke. If you have back problems and seek a chair to help at least not make them worse this chair is not for you. I completely regret buying this and wish I had paid more attention to the lower-star reviews.
