I've noticed the price for this thing fluctuates like crazy so if you can get it in the $65 range like I did, you can upgrade it for just a bit more than MSRP.First off, upgrade the casters. The ones that come with the seat are pretty terrible. They don't roll well, the locking mechanism on mine simply did not work at all, and they make a ton of noise when rolling.I upgraded mine with the Homhoo 3" Stem Caster Wheels purchased from Amazon for about $28. You will have to drill out the existing caster stem holes to make it fit but the upgrade is massive. They roll smoothly and quietly and the lock actually works. Plus there is a lock on all 4 wheels instead of just 2.2nd upgrade is get a seat cushion. The stock seat is hard plastic. You can get a hard foam pad from Adams designed for the seat but even with that, it's still hard on your rear after an hour of detailing. The seat measures about 18x10 so I found a cushion (of course also on Amazon) that fits perfectly. It is the Tromlycs Saddle Stool Cushion 18x9.5. It comes in multiple colors including black if you want it to match. I got grey because it was on sale for $5 less than normal. The great thing is if you have the Adams pad, you don't have to make any modifications of any kind to make it work. The straps are long enough to go around the Adams pad and still are long enough that when the pad is pushed down onto the plastic seat, it still holds it in place. Otherwise, you would need to cut some slots in the plastic (see pics for location) to feed the straps through. You could also cut the straps off and just put the pad on top of the seat and let the little grippy dots keep it in place.Overall, I'm very happy with the seat now that I've added the upgrades. 5 stars with, 4 without.
