I have two gorgeous counter height stools from McGuire of San Francisco.
Both have thick super solid chrome bases and tightly woven waterproof seats that are in MINT condition - see my pics.
The cushions have adorable vintage graphics of plucky little blue birds, but they are not in mint condition. One is in very good condition with only a small stain in the back corner. The other one has two ripped areas on the front edge that will either need a careful graft of fabric from the bottom, or replacement, or just an inexpensive stretchy fabric covering like the one I show in a medium brown - (which comes in a lot of colors and costs just $12 on Amazon.)
The foam inside each cushion is in excellent condition, not yellow or crumbly.
These counter stools are built incredibly well, with really beefy metal, flawless chrome, quality hardware, long welds at the footrest, and grippy transparent feet - see pics.
Some things are built to last several years, these are built to last several decades.
If you buy both you can get the pair for $1,600.
The last pic is a screenshot of Chairish.com where a set of 3 of these is listed for $4,500 in Greenwich Connecticut.
Pickup weekdays before 2pm, anytime on the weekend. West street between Bank and Bethune street - see the map on Craigslist.
See my other listing for a great size B Aeron chair, and a gorgeous Eames Soft Pad chair.
