Stair Lift for WWII Veteran

My Stepdad is 93 years old and a WWII Veteran who served aboard the USS Ticonderoga. We (My Mom/his Wife Audrey, Myself and my two kids and my grandson) just moved into a townhouse and desperately need a stair lift for him to be able to get safely upstairs to the bedroom and restroom.  We had someone from Acorn Stairlift come out to give an estimate and that is the goal we set for this gofundme. Please help me help him to maintain his independence. This stair lift will do that.  If you could please share this with any and all you know then we would deeply appreciate the help.
