Thrilled!   Absolutely Thrilled!  It is exactly what I needed and wanted and it's everything I was hoping for.  Easy to assemble and the cylinder seems to be holding up.  I will reserve judgement on the long term until I have had it for awhile. I messaged Wayfair wondering where my chair was, as this was a replacement for the one that I ordered Nov. 29th 2023, and I finally got the chair I wanted today, Jan. 16th, 2024.  It took longer than I was hoping for, but it's worth it.
