The assembly went smoothly but I recommend necessarily a cordless screwdriver, otherwise called arm's muscles work but it should be clear to each reasonably rational a thinking man eh.
Negative at about 100 kilograms live weight the roles mitlerweile greatly deformed on floor and no longer roll .. but since our floor is sloping, which is bearable for me. ;)
Otherwise, I have nothing to complain about in the chair, everything else works flawlessly.
