I purchased this cushion for a power chair my father got recently. The dimensions stated that the cushion is 22" long and 18" wide. But upon receiving the cushion it was the opposite. Call me crazy, but wide should be left to right as you sit in the chair and length should be back to front.I know most wheelchairs are wider than they are deep but depending on how a power chair is custom configured, it can be the other way around.They need to clarify their description or provide a picture with dimensions on it to avoid further confusion. I'll be returning the cushion unfortunately because otherwise it seems like it would provide good support.
