A chair for fishing alternatively upon a pier and a pond bank, the pond bank being sloped at an angle with respect to the pier, the chair including a seat; left and right legs which are fixedly attached to and extend downwardly from the front end of the seat; left and right quills which are fixedly attached to and extend downwardly from the rear end of the seat, wherein the extensions of the left and right legs are greater than the extensions of the left and right quills; wherein the stems have lower ends, wherein the stems are received within the quills, wherein the quills and stems are adapted for, upon the pier fishing extending the stems' equally with respect to the legs' extension and for, upon pond bank fishing, retracting the stems until the legs' and stems' lower ends are a plane sloped at the angle.

An improved tiltable stool comprises a seat, a body structure, and a base. The base comprises an annular elastic base member having a downwardly convex outer surface and a downwardly concave inner surface. Deformation of the annular elastic base causes a stabilizing force which pushes the tiltable stool towards a normal position when the tiltable stool or chair is tilted out of the normal position. The stabilizing force increases with the weight of a user and provides a consistent dynamic seating experience for users of different weights. An upper section of the annular elastic base is substantially cylindrical and firmly connected to the base structure. The downwardly convex outer surface of a lower section of the annular elastic base member rests on the floor. A contact area between the annular elastic base member and the floor is substantially ring-shaped, and grows outwardly with an increasing weight placed on the seat.

Embodiments relate to apparatus comprising a seat, a base for supporting the seat, and a mounting bracket connecting the seat and the base, wherein the mounting bracket comprises a first portion, a second portion and a flexible joint joining the first portion and second portion; the first portion connected to the base via a first connection member; the second portion is received by a seat comprising a receiving member, wherein the receiving member is connected to the seat using a second connection member; wherein the second portion moves between a foldable position and a release position relative to the first portion; wherein the mounting bracket is configured to be locked in foldable position securing the seat to the base; and wherein the mounting bracket is configured to be in release position for assembly and disassembly of the seat from the base.

A portable, folding chair. Two front leg supports are pivotally connected to a seat frame and extend downward from the seat frame. Two rear leg supports are also pivotally connected to the seat frame. A majority of the length of each rear leg support is positioned above the seat frame. Two individually adjustable front legs extend downward from the front leg supports and two individually adjustable rear legs extend downward from the rear leg support. A front foldable leg brace is connected between the two front leg supports and a rear foldable leg brace is connected between the two rear leg supports. In preferred embodiments, the chair may be utilized in a variety of seating arrangements, such as: bleacher seating, concrete stadium seating, slope seating, flat surface seating and uneven surface seating.

A leg extension apparatus mounted to an existing chair leg to level the chair on an uneven ground is provided. The apparatus includes a bracket assembly having a leg bracket, a first shell bracket coupled to the leg bracket and having a first slot, and a second shell bracket pivotably mounted to the first shell bracket and having a first slot, the first and second shell brackets able to pivotably adjust to an open position to receive the leg of the chair and a closed position to permit the leg of the chair to be enclosed within the first slots of both the first and second shell brackets, and a leg slidably mounted to the leg bracket. The leg slidably adjusts to one of a plurality of locking positions to permit an end of the leg to contact the uneven ground, thereby supporting the chair in a leveled position.

A portable chair includes a frame and a sling for accommodating a seated user. The frame includes an upper back pair of bars, a lower back pair of bars, a hub configured to couple the upper back pair of bars to the lower back pair of bars, a middle pair of bars configured to be coupled to a corresponding one of the lower back pair of bars, a front pair of bars configured to be coupled to a corresponding one of the middle pair of bars, and a front joint configured to couple the front pair of bars to each other.

An adjustable chair includes an upper frame configured to carry a seat, and a lower frame pivotably coupled with the upper frame and configured to support the upper frame above a ground surface. The adjustable chair further includes an adjustment mechanism that is selectively movable between a plurality of positions for securing the upper frame relative to the lower frame in a corresponding plurality of orientations. A method of adjusting an adjustable chair including a first chair portion carrying a seat and a second chair portion includes providing the first chair portion and the seat in a first orientation relative to the second chair portion. The first chair portion is pivoted about a first pivot axis to provide the first chair portion and the seat in a second orientation relative to the second chair portion.

A vertical adjustment mechanism for adjusting the height or elevation of one or more support structures relative to the reference surface. A chair and spacer may be used to adjust the elevation of the one or more support structures. The spacer may include one or more retention clips and/or receptacles.

Embodiments relate to an apparatus comprising a seat, a backrest, a base, a footrest, a mounting bracket, and one or more wheels; wherein the mounting bracket comprises a flexible joint joining a first portion and a second portion, wherein the first portion is connected to the base; the seat comprising a receiving member to receive the second portion; the backrest engaging with the seat and is reclinable with respect to the seat and foldable onto the seat to form a folded position and further lockable in the folded position; the footrest connected to the seat at a first position, and the wheels connected to the seat at a second position, wherein the second position is at opposite side of the first position such that the footrest is used as a handle, while the wheels support a weight of the apparatus and facilitate transportability of the apparatus.
