    Waited a long time to buy this and weighed many options but kept coming back to the 305. If you are on the fence about which model to buy, this should be high on the list. The adjustable arms alone are worth the cost. If, for some reason, a cushion gets added to the seat, you will want to adjust the arms to accommodate shoulder height. I could not believe the immediate difference in posture from the cheaper regular chair to this one. Plus the wheels are angled properly for easy rolling making all the difference for any caregiver who pushes the chair. Right out of the box the chair fit someone about 5’5″ tall without any adjustments. The factory seat height is 19″ and that worked perfectly. It’s a pretty spendy chair but worth every penny for not only comfort, but weight – it’s so much lighter than most chairs, but still sturdy. There is a little pouch in the back of the chair but we added the Karman back pouch for larger items. The footrests not only swing out but swing under the chair which makes getting them out of the way pretty easy. You can’t fold the chair with them swung under the seat, but that’s a small thing to remember. They also come off with a simple click. We tried out many chairs and found ourselves coming back to this one each time. It’s solid, steady and well put together. It comes with a small set of tools to handle most adjustments. Also, Karman has plenty of parts on their web page should you need those. Plus if you call them, they can generally answer questions, depending on who you get on the phone – I’ve had great luck and really bad luck. Overall, this is a perfect out-of-the-box wheelchair. Easy to use, easy to push, comfortable to sit in and promotes good posture.
