These are type of chairs that will last a lifetime or two. i love the swivel option, and not having to slide chairs back and forth on my wood floors, damaging them.  in regards to screws not being aligned i saw in another review..... i had it in 1  of the 3 chairs i orderdd with one screw. nothing a mallet didnt fix, and dont screw it tight till all screws are in, that makes it shift and will be the issue with alignment in assembly, if it happens. similar to assembling solid wood furniture.
