spring/down or foam/down for seat cushion?
Looking at a Stickley chair (the Brookline) that offers spring down as standard. On some chairs it is an upgrade. I can see the difference in the cutaway model but can't seem to get a straight answer on what the differences are -- feel, durability -- and which is better. This is for a chair that will get a lot of use but we are small light people. I guess I am more interested in comfort than durability. In the store I sat in both (at least the sales person said they were one of each kind) and could not really tell the difference. Would appreciate any insight or experience with this . . . Thank you!
