   For chair seats maybe,  that is maybe... I would use splines or some type of glue or lock joint.  For the joinery it would be better to use mortise and tenon.  Chairs take a lot of abuse, the stronger you can make the joint the longer lasting the chair will be.  Biscuits do add a bit of strength but are mostly for alignment of the wood parts.

   DK that you can put the "accepted limitations" title on many things in woodworking. Subjective measures don't lend themselves to black and white so easily. It's your first post, so navigation may prove useful. If you look at the top left you'll see the advanced search feature. If you look up recent discussions on biscuits, you'll turn up loads of worthwhile gouge. My vote would be decidedly against using them in a chair, for the strength concerns mentioned.

   You would be better off looking at two previous articles on strength of joints done in FWW a few years back. You could look in the index. Biscuits were fairly strong but when they failed, they failed completely while M & T were much stronger and failed more gradual. Don't quote me! Chairs would be a definite no in my opinion as well.
