Coir fiber coconut upholstery fiber filling horsehair substitute.
Used in traditional upholstery as a stuffing, can be used with horse hair, or as a cheaper animal friendly alternative. Coir fiber is the husk of the coconut, this makes for an incredibly versatile & springy upholstery filling.

Is that easy to form into those molded rubberized mats?

Yes, German vehicles used coconut fibers, older American vehicles used horse hair .

The image posted clearly illustrates why I always mention covering the bare springs with muslin , canvas or something before putting the buns, used or new on them .

My problem had been : the thin cloth at the unseen edges of the seat covers is dry rotted and needs to be addressed else the cover will come loose again soon .

I don't have a sewing machine nor the skills to replace the crispy delicate cloth .

I _do_ have some very nice covers harvested I want to try to place over my old unbroken spring boxes .

As promised here are the images of my rear seat respring. It worked well. I just wired in some springs along the front edge of the seat then replaced the covers. Cured the sag. I removed all my pool noodles.

Before:


The fix:


detail


all back together with much better contour. no more sags.

Nice work!

It’s great seeing people restoring their seats.
Too often you see someone dealing with rust, a bumper, a paint chip, or say, the red of their seat belt buckle receiver, meanwhile living with totally bombed out interiors.

After vacillating for over a year, I had my backseats pleats restored by a local upholsterer.
It’s like a new car now.
