We had a 24 inch board that worked, but not well in all transfers. It depends on the receiving chair and positioning of the wheelchair to it. A longer board was recommended by a Physical Therapist. Shopping on line I found a number vendors selling longer sliding boards. There was quite a price range, but they all looked the same. Walmart's price was a third less of one price and two thirds less of another. No brainer! I ordered on line and arranged pick-up at a convenient Walmart location and paid no shipping. The store personnel were friendly and helpful. The board is of the quality of shorter board for which we paid more. In trying it out we found the extra 6 inches make transfers easier and safer. Thank you Walmart.
