Assembly was straight forward but construction features for a simple seat was too ambitious. The base is solid holding the bottom base post. However the base post holding the seat post needed to be tighten so much that I was afraid that I would break the quick release clip. If it wasn’t tightened up super-tight then the seat would slide down to about a foot off the deck. From the seat post to the seat, the quick release that allows the seat to tilt is nice and is firm but not required for my purposes. Seat is very comfy and cushiony.
