A chair includes a back member and arm brackets. The back member is tapered toward an end that is adjacent to a seat. The arm brackets are attached under a bottom portion of the seat. Each arm bracket is adjustable to provide a seat clearance area for the seat when one or more of the arm brackets are adjusted up to approximately 90 degrees from an original upright position.

A body support assembly includes a seat assembly and backrest assembly supported by a tilt control assembly. Methods of using and assembling the body support assembly are provided.

A chair includes a leg 1, a seat 5 including a pressure receiving surface PS, a backrest 6, and a support mechanism SM. The seat 5 can move in the front-rear or left-right direction along a predetermined trajectory and to downwardly incline a tip side of the seat 5 in a movement direction in accordance with a movement of the seat 5 from a predetermined reference position (S). The support mechanism SM includes a return-force generation unit configured to generate, in accordance with an amount of movement, a return force in a direction in which the seat 5 moved from the reference position (S) in the front-rear or left-right direction is returned to the reference position (S), and movably supports the backrest 6 in the left-right direction together with a movement of the seat 5 in the left-right direction.

Provided is a rocking chair having a seat body for a user to sit on, a support body for supporting the seat body from below, and a connecting mechanism provided between the seat body and the support body to move the seat body along a surface of a sphere centered on a base point above the seat body in response to an external force applied to the seat body. The connecting mechanism is composed of at least three sub-mechanisms, each of which has a circular track section on the support body side, a linear track section on the seat body side, and a connecting section to interlock their movements. The circular track section has a first traveling member and a first guiding member for traveling the first traveling member along a circle. The linear track section has a second traveling member and a second guiding member to make the second traveling member travel along a surface of a concentric sphere centered on the base point and in a linear manner when viewed from a direction parallel to a central axis of the circle wherein the first traveling member travels. The connecting section has a connecting member that is connected at both ends to a first retainer that holds the first traveling member and a second retainer that holds the second traveling member, and at least one of the first retainer and the second retainer is rotatably connected to the connecting member.

A rotary hanging chair comprises a cushion, a support frame and a base assembly. The cushion has two ends connected to an upper end of the support frame and is able to swing forwards and backwards with respect to the support frame. A bottom of the support frame is connected to the base assembly and is able to rotate within 360° with respect to the base assembly. The entire rotary hanging chair comprises three detachable parts, thus being simple and practical in structure, not only can swing forwards and backwards like a traditional hanging chair, but also can rotate within 360° to change the direction freely to meet the requirement for switching the view angle, and is small in size, easy to carry and capable of being used both indoors and outdoors.

A tiltable stool includes a seat which is connected to a base by an elongated body structure. The base has an upper base element and a lower base element. The upper base element is resiliently deformable. The resiliently deformable upper base element allows the stool to pivot in any direction. The lower base element is a rotationally symmetrical outwardly convex and inwardly concave body. The upper base element may include one or more annular grooves.

A seating arrangement includes a seat portion, a back portion, a support member caused to move between first and second positions, and a back recline lock arrangement that includes an actuator, a lock member caused to move between a locked position when the actuator is in an engaged position where the lock member prevents the support member from moving from the first position toward the second position, and an unlocked position when the actuator is in a disengaged position, and wherein the actuator is configured to move from the disengaged position to the engaged position when the chair back is in the reclined position, and the lock member is prevented from moving from the unlocked position to the locked position until the back assembly is moved from the reclined position to the upright position.
