I did a lot of research, there is a lot to take in. Finally decided on this chair because it has removable leg rests, quick release wheels, folds down small, lightweight, has flip up arm rests that adjust, other adjustability and it is sharp looking. It does meet all the criteria. First Impressions *It came out of the box with no argument, voila! *It's not quite as flashy as some of the Karman chairs, (I love the red), but it's not shy and it is a really nice looking chair. *Leg rests pop on and off easily with a release handle - a comfortable angle here for the legs - I like the foot straps quite a bit, but uncertain about the actual foot rests themselves. *The fact that I took it out of the box myself was a great thing! *Arm rests are great, very comfortable shape and length, the curvature allows more of a straight arm drop for self propulsion - excellent, if we can get height right. *Side guards are really nice, should stop some of the slinging up to the chair from wheels, they curve outward a bit over the wheel under the arm rest, more like a fender - very different. *The handles for the attendant use are nice and my husband likes the height of them, as well as the angle. * Wheel locks are good, I like that the handle flips out of the way. *Seat cushion is a bit of a joke - very thin, sits only in middle of the seat which means those metal rails on the side of the seat are now on your hips. I knew I would need another cushion anyway. *** Adjustment problems! For me the seat needs to be lower, the arm rests are too high, etc. The curvy sideguard seems to rub my forearm when I propel. *This chair does not come standard with anti tippers, though I would have sworn Karman said it did, sigh - that is a bummer. It does have little step helpers for using a foot to aid with bumps and curbs - those are handy. Overall the chair has a lot more composite/plastic parts than I thought. In all the specs, sales videos, etc it was not mentioned that a major component was not made of aluminum. It's a narrow chair, I like that - but some might not. I've rented chairs for years and always the standard 18" and had lots of extra room, but it was time to get my own and I got measured properly. I measured out at 16, but was more comfy at 17" - this is an 18", but frankly is not as wide as others in the past. It's a snug 18" and that suits me. *******Adjustability is very limited without purchasing more parts. If we lower the seat - as in raise rear wheels, the castors cannot be adjusted accordingly without buying new castors and forks. The entire chair seems to be aimed at adjustments towards a taller or larger person, rather than smaller. *Arm rests do not lower, foot rests can't come up any higher, etc After two days of studying on the thing, I am totally and completely unimpressed. Amazon got it here quickly and thanks for picking it up just as fast.
