I wish to double check and seek recommendations for gluing tenon and moritse joints for large dressers to allow for wood movement on carcase sides.

I can glue the front mortise and tenon jpoint for the drawer divider and runners but keep the back tenon a bit looser with a bit of paraffion on them correct!  Or is it better to have a snug tenon joint at the front but do not glue it?

Thanks
