Thousands for 10 is an excellent chair, but it was bought for 18 and I’m very sorry, it hasn’t even been a year since the gas lift has already broken down during normal daily use, it’s a pity, the chair itself is very comfortable. I wrote an application to support, let's see what they offer, 1 year warranty. The only thing is that the view is not marketable, the cat loves to tear its claws about it
