A bag includes a main compartment configured to accommodate equipment, and a foldable chair compartment disposed adjacent to the main compartment. The foldable chair compartment is configured to accommodate a foldable chair in a folded configuration.

A bag includes a main compartment configured to accommodate equipment, and a foldable chair compartment disposed adjacent to the main compartment. The foldable chair compartment is configured to accommodate a foldable chair in a folded configuration.

A foldable chair has frames connected to one another by cross supports, bases connected to the frames by base supports and frame supports, with springs secured between the base supports and frame supports to allow for back and forth movement of the frames when a user is seated in the chair. The foldable chair includes a pliant membrane providing a seating surface for supporting the user.

A connection structure for a composite backrest and a method for making the same are provided. The connection structure includes two frames, a backrest body, and metal bushings. The metal bushings include a group of left metal bushings and a group of right metal bushings. The two frames are respectively fixed to the left side and the right side of the backrest body by the left metal bushings and the right metal bushings. The method includes: punching the backrest body and the frames; placing the frames into the backrest body; processing the metal bushings; sandblasting or sanding the external surface of the metal bushing; coating a configured structural adhesive on the metal bushing, and oppositely bonding the metal bushing; fixing the bonded metal bushing by a tool; and placing the fixed metal bushing, the composite backrest and the two frames into a drying oven for heating.

Devices, systems, and methods for use of a stowable seat topper are described. The stowable seat topper can include a seat portion, a back portion attached to the seat portion, arm portions attached to the back portion, and cushion portions attached to the back portion. The seat topper can include fasteners configured to secure the seat topper when in a stowed state. The seat portion, back portion, and arm portions can comprise molded foam and provide ergonomic support to a user. Furthermore, the seat topper can be configured to transition between a stowed state and a deployed state. In the stowed state, the seat portion, back portion, and arm portions can be rolled together and securing in placed by fasteners. In the deployed state, the seat portion, the back portion, the arm portions, and the cushion portions can be unrolled, aligned with a seat, and secured to the seat.

The present invention relates to seat systems, and more specifically to seat systems suitable for supporting users sitting in a cross-legged or kneeling position during activities such as meditation. Sitting closer to the ground, cross-legged, and/or kneeling enables the brain to easily enter a parasympathetic mode, providing users of the seat system a greater sense of calmness. The Multi-Angle Knee blocks (MAKs) offer a greater level of hip support for users.

A mesh hook surface fastener does not lose engagement ability even when subjected to mold-in forming and gives only a slight feeling of something foreign. The mesh hook surface fastener contains first shape holding ribs (a.sub.21) with a relatively small protrusion height and second shape holding ribs (a.sub.22) with a relatively large protrusion height which protrude to the opposite side of hook-shaped engagement elements (B.sub.1, B.sub.2) across a base layer (A.sub.1) and are alternately arranged. The heights of the adjacent shape holding ribs (a.sub.21, a.sub.22) are different, which prevents the direct entrance of a foamable resin liquid and weakens its force. As the force weakens, foaming and curing progress more readily and, as a result, the amount of the foamable resin liquid that passes through meshes of the base layer to reach the hook-shaped engagement elements can be reduced.

A chair seat capable of adjusting a width contains a base, an adjustment assembly, a first sitting portion, a second sitting portion, an adjustable clamp portion, a first guide member, a second guide member, a central shaft, and a screw bolt. The base includes a threaded orifice, multiple locking orifices, a support portion, and a groove. The adjustment assembly includes a first wing and a second wing. The first sitting portion includes a first tilted supporting face. The second sitting portion includes a second tilted supporting face. The adjustable clamp portion includes a guiding orifice. The first guide member includes a first oblique press face and a first connection orifice. The second guide member includes a second oblique press face and a second connection orifice. The central shaft includes an abutting face, multiple fixing orifices, and multiple screws inserting. The screw bolt includes a rotary knob and a non-threaded section.

A functional sitting chair according to an embodiment of the present disclosure effectively distributes the user's body pressure even when the user sits for a long time, stably supports the user's waist and back, provides a heating function, and maintains great comfort by effectively circulating air through a pattern formed on the cushion.
