[0078] The rod-shaped element 31 , the rod-shaped element groove 36 and the slot 32 may have a substantially circular shape, but may also have other shapes, such as a triangle, a rectangle, a square, etc.

[0079] The rod-shaped element 31 may be made of one or more of a wood-based material and a polymer material, which may include a reinforcement material, such as glass fiber or metal. The rod-shaped element 31 may have a waxed surface to facilitate assembly.

[0080] The first panel groove 14 may include a width W1 .

[0081] The second panel groove 24 may include a width W2.

[0097] When the first panel 1 , the second panel 2 and the back panel 40 have been assembled, the locking mechanism 50 can be assembled to the set of panels. The locking mechanism 50 is inserted into the first panel groove 14 and / or the second panel groove 24 to lock the first panel 1 to the second panel 2.

[0098] The locking mechanism 50 may lock the back panel 40 to the first panel groove 14 and / or the second panel groove 24 , thereby preventing the first panel 1 from shifting relative to the second panel 2 in a direction opposite to the assembly direction AD.

[0099] The locking mechanism 50 may be made of, for example, a wood-based material, metal, a polymer material, or the like.
