A first sleeving opening, a second sleeving opening, and a third sleeving opening are arranged in sequence and correspond in position. One end of a second support rod and one end of a third support rod pass through the first sleeving opening, the second sleeving opening, and the third sleeving opening in sequence and are connected to the first support rod, so that the base and the armrest form a whole.

The present invention discloses a sofa module, including a sofa seat, where a top surface of the sofa seat is provided with at least two splice slots in a region close to each side edge, and a first splice member and a second splice member corresponding to the splice slots, where the first splice member includes a first insertion rod inserted in the splice slot and a first connection rod that has one end connected to the first insertion rod and the other end connected to a back plate; and the second splice member includes a second insertion rod inserted in the splice slot, a second insertion rod configured to be inserted in an adjacent splice slot of the sofa seat, and a second connection rod connecting the second insertion rod to a third insertion rod.

A chair seat combined with two armrests, each comprising crossbar with first toothed structure, is provided. Chair seat includes base and clamping devices. Base comprises armrest slot and mounting holes, where armrest slot accommodates crossbar and mounting holes are connected to armrest slot. Additionally, each of two clamping devices, installed in the two mounting holes, includes mounting base, clamping element, operating component, and transmission element. Mounting base is installed and fixed in mounting hole, with one side of mounting base having installation groove. Clamping element is installed in installation groove and has second toothed structure facing first toothed structure. Operating component is positioned on other side of mounting base relative to installation groove. Transmission element connects clamping element and operating component. Operating component is adapted to drive transmission element, causing clamping element to move towards and clamp crossbar, thus enabling second toothed structure to engage closely with first toothed structure.

Presented is a multi-positional travel armrest or device, that rest on the lap or abdomen while in a user is in an upright reclined seating position and is specifically designed to support and protect their arms and elbows from forced vibrations and shocks, thus relieving tension on the shoulders and neck, reducing the effects of fatigue caused by travel or sedentary behavior. The armrest or device is a six-sided with a middle portion there between a first portion and a second portion that form wings. A 5.sup.th side of the device has first recess surface connected to a second recess surface that slopes from first recess surface toward a bottom side or base. The 5.sup.th side is a back side when disposed on a user's abdomen with the bottom side in the user's lap. A third recess surface on the base accommodate zipper and clothing bulges providing added comfort.
