Abstract: A seat armrest comprises an elbow-rest segment, an arm-rest segment, a mobilizable connecting structure, and a height-locking structure. The elbow-rest segment is connected to a seat. Both the mobilizable connecting structure and height-locking structure are connected to the elbow-rest segment and the arm-rest segment. The mobilizable connecting structure facilitates the arm-rest segment to surround the mobilizable connecting structure to pivot toward a space above the elbow-rest segment. When the arm-rest segment is pivoted to any desired height, the height-locking structure can fix the arm-rest segment on that desired height. As a result, the user can adjust the height of his forearm on the arm-rest segment freely at different heights according to different occasions, so that the user can rest his forearm comfortably.

Abstract: A chair has a seat, a backrest, a lift structure, a back supporting structure, and a waist supporting structure. The backrest is deposited behind the seat. The lift structure is deposited on the backrest. The back supporting structure has a bending element and multiple supporting strips. The bending element is connected with the backrest and the lift structure, and is elastic and bendable to deform. The supporting strips are deposited on the bending element at spaced intervals from a top to a bottom of the bending element. The waist supporting structure is deposited in front of the back supporting structure. The waist supporting structure has two pivoting bases and a supporting plate. The pivoting bases are deposited on the seat. The supporting plate is pivoted between the two pivoting bases, abuts the back supporting structure, and selectively abuts the backrest.

Abstract: A multifunctional storage device has a lower seat with a storage room, an upper mount pivotally connected to the lower seat, a bottom cover mounted on the lower seat, and an adjustable connecting assembly connecting the lower seat and the upper mount. The upper mount can cover the lower seat or can be opened to tilt relative to the lower seat and be held at a specific angle by the adjustable connecting assembly. When the multifunctional storage device is attached to a piece of furniture, the upper mount is flush with a platform of the furniture, such that articles can be placed on the upper mount and the platform of the furniture or be stored in the storage room. Accordingly, the furniture with the multifunctional storage device can have a basic function and multiple additional functions derived from the multifunctional storage device.

Abstract: An adjustable chair has a seat and a splat. The seat has a lower base, an upper base, a tilt adjusting device, a lower rotating shaft, and an upper rotating shaft. The lower base has an assembling space. The upper base is movably deposited on the lower base. The tilt adjusting device is deposited in the assembling space. The lower rotating shaft is rotatably deposited in the lower base and connected to the tilt adjusting device. The upper rotating shaft is deposited in the upper base. The splat is tiltably connected to the seat and has a backrest unit and two connecting legs. The backrest unit is deposited at a rear side of the seat. The connecting legs are connected to the backrest unit, are connected to the lower rotating shaft, and are pivotally connected to the upper rotating shaft.

Abstract: A liftable table has a table frame, a fixing board, a lifting device, and a table board. The table frame has a main frame and a holding seat. The holding seat is deposited on the main frame. The fixing board is mounted on the main frame. The lifting device is deposited on the holding seat and has a driving set and at least one crossing set. The crossing set is extended from or folded in the receiving space of the holding seat, and is connected to and driven by the driving set. The table board is deposited on the crossing set to move upwardly or downwardly. A user views and operates a computer put on the table board with a sitting or a standing posture, and this prevents the user from using the computer with the sitting posture for a long time and avoids damages to the user's health.

Abstract: A chair has a seat member and a backrest member. The seat member has a seat body having a horizontal frame disposed horizontally; a front supporting leg mounted on a bottom surface of the horizontal frame near a front end of the horizontal frame; and two rear supporting legs mounted respectively on two sides of a bottom surface of the horizontal frame near a rear end of the horizontal frame. The backrest member has a backrest frame having two backrest sidebars mounted respectively on two sides of the horizontal frame and an upper crossbar connected between two top ends of the backrest sidebars and having a suspension slot defined in a rear surface of the upper crossbar. The suspension slot is axially elongated and has an L-shaped cross section. The chair may be used independently and may be easily combined other furniture units to form a furniture set.
