U Hau; rents vans one way. it costs more but might be worth it.
I reupholstered LOTS of furniture by taking local community college non
credit class. Really got into it did over a time a kitchen set of
chairs, a nice recliner, a big overstuffed chair, 2 wing back vinyl
chairs, my cars seat, and some other misc stuff. I kept taking the
class the teacher did the sewing for me, I was helping teach by my last
Its a LOT of work but well worth restoring older quality furniture.
As to the spring it will be difficult to just replace the spring, just
redo the chair///\\\\
Springs can break but generally its the webbing and tying that fails
making it appear its a broken spring........
