[0022] The present invention will now be described in further detail with reference to the accompanying drawings.

[0023] like Figure 1-3 As shown, the armrest includes a left armrest 1 and a right armrest 2 that can be installed together on a seat or sofa. The left armrest 1 and the right armrest 2 are arranged in a mirror-symmetrical configuration.

[0024] Preferably, the left handrail 1 and the right handrail 2 can be made of suitable materials such as plastic, wood or metal.

[0025] like Figure 1-2As shown, the characteristics of the armrest are described using the structure of the left armrest 1 as an example. It is assumed that the side facing the seat or sofa is the inner side and the opposite side is the outer side when it is installed, and the side facing the backrest is the rear side and the opposite side is the front side.

[0026] Multiple through openings 3 are provided on the upper part of the left handrail 1, which not only saves materials but also increases air permeability. Each opening 3 can be set at any suitable position, such as the upper, middle, or lower part of the left handrail 1, without affecting other structures. As shown in the attached figure, openings 3 are provided at all the above-mentioned parts of the left handrail 1.

[0027] A through-hole 4 is provided on the front of the inner side of the left armrest 1, and a switch mounting slot 5 is provided on the front of the outer side. The switch mounting slot 5 can be used to install the switch of the electric seat or sofa, and the through-hole 4 can be used to pass cables.
