Last summer, I got 4 DSR chairs from Herman Miller, with felt glides to protect my hardwood floor.
We use them everyday and have no problem.
I added 2 DAR chairs some weeks ago and the felt pads are already slipping off the glides.
Does anyone else have this problem ?
I have spent some time this morning analyzing what could be the source of this.
I used a digital protractor to measure the angles of the chair legs and made a surprising discovery.
DSR
Leg angle : 24°
Leg curve before feet : 13°
Leg angle at floor : 11° (24° - 13°)
Glide tilt : +/- 6°
Glide angle at floor : ≈ 5° (11° - 6°)
DAR
Leg angle : 30°
Leg curve before feet : 13°
Leg angle at floor : 17°
Glide tilt : +/- 6°
Glide angle at floor : ≈ 11°
Picture :
In both cases, the glides are not parallel to the floor.
And in the DAR case, the angle difference with the floor is way too much for the felt adhesive to resist.
I can't seriously be the first to realize this fault !?
Ball socket at foot?
I'm not familiar with contemporary production eiffel tower bases, but the vintage chairs (except the 1st generation) had a ball and socket connection at the foot which allowed the foot to adjust to an uneven floor. I assumed the current production was made in the same manner and would be shocked if the feel are not self leveling.

HM has modified the legs of the original design, which had narrower legs. Well done !
Best possible resolution.
Illustrates a commitment on HM's part to ongoing customer service. Good on them.
I just wish that when the shock mounts started popping off my set of DCMs, they could have come up with a solution that didn't involve shipping all of the chairs back to MI at my expense.
