We would like to fasten the seat back to the surface behind it (please see photos).

Ideally, we would like NOT to drill holes in the surface behind. The surface is very hard plastic (maybe melamine?)

The seat back weights 15kg and has a metal rail on it, which attaches to another metal rail (that we would mount to the surface).

Would there be some glue, which would be strong enough to hold the seat back - and let's say we want to remove it from the surface in the future, would it be possible? We don't really want to glue it on and not be able to remove it in the future, without damaging the surface.

What sort of forces does the rail need to hold?
Is it holding the full weight, or is it just stopping it falling forward?

If it's just stopping it falling forward, it possibly consider some good double sided tape.
The key is good tape and clean surfaces.

It will need to hold the full force. Therefore, it will be raised above the seat (not resting on the seat, as it currently is).

If we just allowed it to rest on the seat, we wouldn't be able to open the seat (there's storage beneath).

could also try 3m command strips - something like these.
They probably have better suited ones

The seat back weights 15kg, so do I just get 3 x sets of the strips (as they hold 7.2kg each)?

3M automotive double sided tape.

This is the first place that pooped up on goggle after a search but it gets sold quite a few places.

Have you considered modifying the seat?

You could add a sheet of something to the back of the base to hang the back cushion from.

Thanks. Doesn't specify weight limit though.

I would consider velcro tape. Enough used and it will hold a bit of weight. Easy to remove it if you need to as well, as you can just pull the seat back off.

For $18.20 delivered, I think it's worth a shot anyway. I haven't used it in this situation before, but in my head it makes sense.

If you find it not holding, add more tape strips, do them vertically full height of the seat you want to stick and every 400mm and the only problem will be removing it.
