Enough for 3 days! On the third day of use, I noticed a skewed back of the chair. I thought about fixing it, I removed the back plastic wall of the backrest, and there the mounting base was made of THIN PLASTIC. Which naturally could not stand it and hesitated somewhere, and where the nut was fused, it completely broke off. This is not a chair - this is a props. It is not clear what the manufacturer was hoping for when making such a g. .
