Replacement seat for knee walker seat

The seat arrived fine, albeit a bit slow, for the Drive 790, old version. The bolt holes were a bit off on the back set of 2 so had to make some adjustments

Wrong model

Wrong model but we made it work. We needed the 780, but got the 790.

Scooter Part

Arrived on time, exact fit for install. All is good.

Replacement knee seat

It is the exact part I needed and is very comfortable on my knee. The representative I talked to went above and beyond finding what I needed. She was very helpful, pleasant, and knowledgeable and a credit to your team.

Parts did not fit

Seat post is a different size. After drilling a few new holes to the existing seat post I made it work.

Thank you for letting us know. Can you please confirm and provide the Drive Medical product number and serial number of your knee walker so that we may report this issue to the manufacturer. As long as it is a Drive brand knee walker, they should be made aware of the potential quality issue. If it is not a Drive brand knee walker, we do not guarantee fitment of or recommend attempting exchanging Drive parts with other brands or models.
