Easy to put together, solid  and comfortable too.   The swivel is very heavy duty  and needs spin time to loosen up as should be expected.   Thats just the nature of  a turntable bearing though, a bit of wd-40 will help it spin easier , but,  Better to have it solid as it is than loose and spin freely before use only having it loosen up and start to rock months down the road.         Very satisfied with the stool!
