Yikes!  These chairs come with sharp metal shavings on the seat!  It must be drilled in the same space the seat cushion is made. It cut my fingers and I had to vacuum all 4 cushions (we bought 4 for our counter overhang). This is a huge safety concern as it would be easy to get the shavings in our eyes or cut your rear. Thankfully my kids were not home and we have a powerful shop vac and I spent 20 minutes vacuuming the tops to make them safe. I’ve added pictures to show all the sharp metal shavings. All 4 separate boxed seats had this problem.  Once this part was solved (via rigorous vacuuming) the stools are great. Comfortable, affordable and good height. Easy to put together, except for getting tiny metal shards in my hand.
