Are you looking to stitch it yourself from scratch? Here is a leather source, not used by anyone I know:

While the 960, S/V90 seats will fit your car, none of the 850/70 seats will work for you.

As for the seat air bags prior to 1999, none of them require electronics to cause them to deploy. It is a self contained system with its own detonator and will activate even with the car locked - so long as someone crashes into the front door hard enough.

I have heard that there are shops south of the border that do good work and are quite reasonable.

Uncle 94 945T,

As Uncle Spook mentions, seat swaps from another Volvo model compatible with your model is useful.

What I forgot to mention:
- Ask this question on the https://www.brickboard.com/AWD/ side of the Brick Board

As you know, Volvo is no longer the REAL people's car. It's all about luxury this and bling-bling on these 21st century models. (They are all sparkly like something bejeweled).

So, the later FWD and the high-end RWD models make more use of glove (over hide) leather.

Some Volvo AWD owners may be able to help you.

- Research on other boards of luxury or special interest auto boards.

Failing leather seat covers is an issue in Mercedes, BMWs, Porche, Audis, and such. You may want to research those motoring enthusiast boards for such information on leather seat cover and opholstery services to build these for you and secure them to the seat.

I'd be concerned about replacing the seat foam under the leather seat covers you want to replace, webbing under the foam in the seat and seat back, and so forth.

- Finally, contact the Volvo stealership. Do some research.

While very pricey, you may still be able to buy factory seat covers from Volvo.

You, if able to, or an auto upholstery services vendor can install these. Or the Volvo dealership may be able to.

That does it for me.

The seat swap is a good idea.

I've also found seat covers on seats in junk yards. Yet I prefer cloth where I can.

If you can find worthy and compatible leather seat covers from a junk yard, as I have, you may be able to have an upholstery and other services to restore the leather to a supple state and also repair the reinforcing textile backing on all auto leather seats.

Now, that does it for me.

Dear 94 945T,

Hope you're well. I stood aside, in the hope that some better-versed in upholstery would offer advice.

Be advised that seats from 1993 and later 960s and S/V 90 will fit into a 940. You may need to provide power connections: there's a procedure in the FAQs for installing power seats in a car not so equipped.

I suggest a seat swap, as that is likely to cost less than having someone make new seat coverings and install them. The gray leather used in 960s and S/V 90s seems to hold-up far better than than tan leather, which seems quite perishable. As a result, you should be able to find a set of seats at a salvage yard.

With a bit of luck, you'll find a donor car with seats in good shape. Be further advised, that front seats from a '96 and later 960 - and from an S/V90 - have a built-in side-impact airbag. These airbags are self-contained: they cannot be - and do not need to be - connected to your car's airbag system.

If you decide to pull the seats yourself from the donor car, be sure the car's battery has been removed or - if the battery is there - that the negative battery cable clamp has been disconnected from the battery terminal. Removing the battery, or removing the negative battery cable clamp from the battery terminal, ensures that the airbag system is de-activated. The airbag impact sensor is mounted on the floor pan, under the driver's seat. An airbag deployment, at close range, can be lethal.

For the in-seat side-impact airbags to work, a white plastic block - mounted inside the door, at the bottom - must be removed and installed inside the door of your car. This is not hard to do. Installing this block will cause the window to stop such that 1/2" (13mm) of glass sticks-up above the top of the door's inner panel.

This seat upgrade - side-impact airbags and a more supportive design for the seat padding - is likely to cost less than having made replacement leather seat covers.

Hope this helps.

Yours faithfully,

Spook

Uncle 94 945T,

You would want to search for auto upholstery service providers. Sort of a cottage industry for Volvo, I imagine.

You may be able to find auto-grade hide or glove leather sections that may or may not come with backing.

Have you searched the brickboard and turbobricks?

The brickboard.com search is a little finicky.

Use google to target www.brickboard.com by adding to your search query:
site:www.brickboard.com

Sorry I can help you more. I work in cloth and usually pull Volvo factory seat covering, and attempt repair through stitching the heck out of it and repaing the seat and seat back webbing.

Questions?

Others should chime in. Like those with luxury RWD Volvos they want to keep the seat cover in good health or have replaced them.

I have read several threads over the years on Volvo auto upholstery issue.

Hope that helps.

Duffed.
