適合的座墊對於輪椅使用者十分重要,長時間的維持坐姿,若是沒有適當的減壓,便容易出現壓瘡,這時便需要座墊協助。不過並非人坐上去,就能避免壓瘡的形成,座墊的軟硬往往是影響減壓效果的要素之一,太硬減壓效果不佳,太軟容易觸底,壓瘡仍會生成,但何謂最適當的硬度,這對於許多家屬及使用者是個難題。
現在氣墊廠商ROHO研發出一台氣墊型座墊的感應器Smart
Check,接上座墊上特殊的接口後,按下上方按鈕,便會開始檢測座墊內的氣壓,若氣太多上方的紅燈會亮,這時便需要轉開氣孔洩氣;氣太少則是亮下方的紅燈,表示需要使用打氣筒灌氣,待中間的綠燈會亮起,便知已達到最適當的氣壓,可以將氣孔接頭轉緊。這個感應器另外還有記憶功能,可記憶每個使用者最適當的氣壓,之後使用不需再重新設定,直接重新調整座墊。不過目前感應器僅能使用在有感應器接孔的座墊,所以某些型號的ROHO氣墊型座墊才能使用
