What types of joints are used in furniture?

According to the constraints of the furniture:

• Tenon/mortise (solid wood structure): rigidity and longevity.

• Dowels / biscuits (E0 panels): precise alignment, reliable gluing.

• Structural screwing (reinforcements, frames): targeted disassembly.

• Finger-jointing: massive stabilized boards for wide panels.

• Grooving/fitted backs: bracing of the unit.
  The mix of joinery optimizes stability, weight, and durability.
