A motion base (100) includes: a first installation base (1a); a first movable base (2a) on which a placement subject is to be placed and that is disposed on the first installation base (1a); at least two first actuators (3a) each of which is extendable and contractible; first connecting portions (1a) connecting the first actuators (3a) to the first movable base (2a); second connecting portions (4b) connecting the first actuators (3a) to the first installation base (1a); and a spherical surface body (5) that has a spherical surface-shaped portion (15), is disposed on the first installation base (1a), and supports the first movable base (2a) such that an attitude of the first movable base (2a) can be changed relative to the first installation base (1a) by sliding the spherical surface-shaped portion (15).

The present disclosure provides an adjustable bracket for furniture, including a base and multiple support members movably connected to the base; the base includes a lower portion and an upper portion, and the multiple support members include three or more lower support members; the lower portion includes a lower receiving portion configured to receive the lower support members, a screw, and a knob; each lower support member includes a leg and a connection portion disposed proximate to the lower receiving portion; the connection portion includes a first elastic member connected to the lower receiving portion and an end portion away from the mounting surface; the end portion abuts against the upper portion when the legs are in a folded position, and the end portion is tangent to the nut and a tangent point to the nut is changeable when the legs are in an unfolded position.

A portable mattress seating apparatus attachable to a mattress. The portable mattress seating apparatus clips onto a location on the peripheral of any conventional mattress. The apparatus has a retaining member that is retained under a mattress and above the box spring. The retaining member is attached to a vertical member adjacent to the side of the mattress. The vertical member is attached to another seating member that is oriented parallel to the top of the mattress face. The seat member is attached to a back-rest member. The back-rest member is attached to the seating member distal to the side of the mattress. The back-rest member is adjustable, allowing the back rest to be at acute, obtuse or 90-degree angles to the seating member. Further, the apparatus includes supporting members to spread the weight of a seated person.

A chair bracing apparatus(10) comprises four cup-shaped leg holding formations(12) and a bracing structure (4) extending between the leg holding formations for holding the leg holding formations in a fixed special relationship relative to one another. The apparatus (10) is configured for bracing the legs(16) of a chair(18). The bracing structure (14) comprises two elongate bracing struts (22.1) and (22.2) which cross over one another and extend between the leg holding formations (12.2), (12.4) and (12.1), (12.3), respectively. The struts are fixedly connected to the leg holding formations and fixedly connected to one another in the region of the cross over.

A novel sling assembly and corresponding method of stretching sling fabric are disclosed. The assembly preferably comprises a chassis with opposing rails connected by a cross bar. A sling frame having opposing stretch bars connected by a stretchable fabric is disposed over the chassis in a pre-assembled position. A cam lock is inserted into a key hole cut into at least one of the rails; the cam lock is then rotated away from the central axis of the key hole. An engagement member extending from at least one of the stretch bars is then inserted into the key hole. The sling fabric may now be stretched by rotating the cam lock toward the central axis of the key hole to move the engagement member along the key hole until the fabric is taut. The taut fabric is held in place by the engaged cam lock, whereby the assembly is kept in its stretched, fully assembled position. The invention's unique structure thus advantageously makes sling fabric replacement convenient, quick, and without the need for special tools.

A type of two-person folding chair which includes a folding frame, seat area, and backrest area. The folding frame includes support sections on both sides in corresponding positions, and diagonal bar sets that connect the two support sections on both sides. Wherein, each support section includes a bar bent into an open D-shaped structure, which forms, from top to bottom, a backrest bar, an armrest bar, a front leg bar, and a landing bar. The diagonal bar set includes two or more diagonal bar units. The seat bars on the upper portions of the diagonal bar units support to form the seat area.

A portable, foldable, lightweight chair that can be used by boaters, beach goers, and others to relax in a body of water such as the ocean, a lake, a river, or the like. Also, the chair can be used in water up to four (4) feet deep. In particular, the chair enables the user to anchor the chair into the bottom of the body of water (such as into the sand in the ocean bottom) in which the users are using the chair. Furthermore, the chair includes a netted material that allows the water to flow through the chair to ensure that the chair remains anchored to the bottom of the body of water. Finally, the netted material allows the chair to more easily and quickly dry out once the chair has been removed from the body of water.

The seat base may include a frame with a polygonal geometry, a first leg assembly hingedly coupled to the frame, and a second leg assembly hingedly coupled to the frame. The seat base may also include a first leg hingedly coupled to the frame, a second leg hingedly coupled to the frame, and a cross member coupled to the first leg and the second leg. A guide may protrude from the frame. The guide may define a recess. A retention pin may engage the recess and retain the first leg assembly in a deployed position. The frame may also have quadrilateral perimeter. The seat base may further include an interior cross member fixedly coupled to the frame, and a pin protruding from the cross member. The pin may engage a seat. A loop may extend from the frame and engage the seat.

A stepstool includes a stool body and a stability extension. The stool body includes a top step and a support structure that supports the top step. The stability extension projects distally from a base portion of the support structure and extends distally beyond a distal edge of the top step. The stability extension is configured to be received in a toe-space at the base of floor-standing furniture, and the stool body is configured so that the distal edge of the top step can be positioned immediately adjacent to the floor-standing furniture, to provide mechanical interference and thus prevent tipping of the stool body when a user on the top step leans out of balance. Also, the sides of the support structure can be angled outwardly to provide a wider base portion for improved stability of the stool body.
