Up for your consideration is this Per4max SUSPENSION Wheelchair.  I believe this is the Shockwave model (sells for over $3k new), but could be wrong. This wheelchair has a suspension in it.

The seat is 17" wide, I'm not sure if the depth is considered 16" or 15". The sling is 15" deep but up to the frame it is 16". You can see the exact dimensions in the pictures.

The wheelchair is in good working condition  BUT NEEDS NEW INNER TUBES FOR BOTH TIRES.

The tires are size 24".

It will come as shown only.

It is used with regular use wear including scratches and so on. See the pictures for the exact condition.

Free local pick up in Bloomington California is welcome.

Thanks for looking.
