Many people with paralysis feel discomfortness in their activities on wheelchair. Assistive device which can increase comforness is cushion seat wheelchair, but cushion seat with special specification for people with paralysis has high prices. This research is a preliminary study to design alternative cushion seat which comfortable and affordable price for manual wheelchair using value engineering method. There are three criteria and eight subcriteria were raised which were processed by Analytical Hierarchy Process (AHP). Three subcriteria were selected for the priority of requirement design, there is user’s maneuver support as selected subcriteria 1 weighing 0.64221, lumbal protection as selected subcriteria 2 weighing 0.72054 and suitability of cushion seat material to maintain the gluteal temperature as selected criteria 3 weighing 0.83333. Based on selected subcriteria, three alternatives designs were raised which were processed with AHP. Selected alternative is cushion seat with backrest, foam and gel modification which were measured based on selected subcriteria that selected subcriteria 1 weighing 0.70536, selected subcriteria 2 weighing 0.68032, selected subcriteria 3 weighing 0.74084.
