I have a classic B aeron that I ripped the back out of by accident. My fishing line repair only lasted so long before I started looking for a replacement. After being skeptical from the reviews of the bottom seat replacement I took a chance on this. The fit is difficult to get right (abet not 100% perfect) everything fits very tight, and the back is comfortable and supportive. I recommend starting at the bottom and hammering in the plastic insert with a piece of cardboard between (so you are not hammering the plastic directly) Install the bottom screws first. Keep hammering as you work your way through the middle. Unfortunately the top tightens down, but the top is not shaped perfectly to fit 100% in the groove. Its about 3/4 the way in along the top, except 100% where the middle screw torque is. Left and right of that it protrudes just a little, but doesnt change the comfort of the chair, and then 100% to the corners and down towards the top side screws. Maybe over time it will flex a little and fall into place.

Value wise I am very happy with this purchase. HM does not sell just the mesh you need the entire back that costs 190$ new.

The mesh feels of good quality, very similar to the original in feel and aesthetic. Has a new almost rough texture I am sure will break in to match this 15 year old chair.

I give this an A -
