Below, we will consider two ways of constructing chairs, both inseparable despite the application of typical separable and inseparable connections. Figure 4.76 shows the construction of a rattan chair, in which all the elements are connected with metal screws. However, due to the fact that the screws are covered by filling in the holes, and then reinforced with a weave of leather strips (or rattan), the construction is completely inseparable.
Similarly, inseparable is the construction of a carpentry chair as shown in Fig. 4.77. This construction uses only single covered L-type mortise and tenon joints. However, the designed model can be strengthened by connectors glued by means of finger joints in the side surfaces of the rails (Fig. 4.78).
