Touted as ergonomic, this chair is unusable
Beware the hard seat of the ErgoTune chair if you're anything other than slender: the seat is made of a mesh fabric wrapped around a hard plastic frame that digs into the thighs. And if you're buying online, be aware that ErgoTune refuses to take the chair back if you find you cannot tolerate the hard seat. After a few hours on the chair, my feet swelled up and my legs ached, but when I emailed the company about the hard seat, the reply was, "The seat should not be too hard." I emailed back, and they suggested I might like to "gift" my $500 purchase to a friend or family member, because they "do not have a return policy at the moment." I've thrown $500 down the drain and now have to get rid of this useless thing taking up space in my apartment. It appears the company is based in Singapore, although they try to hide their address, and there's no accountability for the defects in their product.
