Nice and comfortable for all day use. My only word of advice is: When assembling put one arm on the seat and the other on the back. Then finger tighten each screw. After they're semi-tight fully tighten each while alternating sides. Otherwise you're not going to be able to put it together correctly.
This was bought for my grandson. 1st to sit and do his studies..... Then for his gaming. He uses it all the time and still thanks me for it after a good gaming session. His school has not started.
