Front seat springs

[ScottD]

I have an 87 Lebaron sedan turbo with console shift and front buckets.

The driver's seat bottom springs are kind of worn. You can't see it when you look at it but when you sit in the seat you definitely lean a bit to the left.

Is this something an upholstery shop can easily fix? I've thought about putting different front seats in the car but they are in really good shape and the color of the interior is a little tough to match.
