Black: sturdy, not creaky. Overlooked for his humble appearance, but will never let you down. Are you a stoic who needs a chair equal or are you a upcycler who will introduce him to his inner beauty?

Grey: has a past.  Lovingly repainted and reupholstered.  Probably will bond for life. Surpringly comfortable. 

Yellow: pedigree. Literally from ikea.  Low back fits comfortably against your lower back.  Too fancy for the dumpster.

Robins egg blue: lightweight. Hole cut out in case you have a tail. One leg is shorter so you do need to put something under one of the feet but the color is so cute it is worth it.
