In one example, a height adjustable desktop system is described that can include a work surface, a foot assembly and a linkage assembly that adjustably connects the work surface to the foot assembly allowing vertical adjustment of the work surface. The linkage assembly can include a pair of adjustment assemblies, each having a transverse linkage that maintains the work surface in a horizontal orientation as the work surface is elevated or lowered. A biasing mechanism, such as an extension spring or a torsion spring, biases the work surface toward the elevated position.

Provided is a sliding and folding bed table with adjustable height, designed for use over beds in confined living spaces such as campers, camping trailers, RVs, rooftop tents, and similar environments. This table is particularly useful in areas where room around the bed is limited or where the bed is positioned close to the floor.

An adjustable desk platform can include: an upper platform defining a substantially planar work surface; a base located beneath the upper platform, the base defining a bottom surface without legs that is adapted to sit on an existing desk; first and second sets of arms coupling the upper platform to the base, wherein the first and second sets of arms are adapted for movement of the upper platform substantially in parallel with the base between a fully raised position and a fully lowered position; and a user-operable locking mechanism associated with the upper platform, the locking mechanism adapted to releasably lock the upper platform in the fully raised position, and in at least one intermediate position between the fully raised position and the fully lowered position. Other features and embodiments are discussed.

A workbench arrangement supportable by a wheelie bin having a worktop with a base portion with dimensions for a frictional fit engagement with upper internal walls of a lid removed opening of a wheelie bin to be laterally fixable in the opening of the wheelie bin. The worktop further including an outer skirt adapted to rest upon a peripheral upper edge of the lid removed opening of the wheelie bin to support the worktop in an elevated flat user workable position. A worktop table extension adapted to laterally join with the outer skirt of the worktop to support the worktop table extension at one end and at least one support leg fastenable at the other end to support the worktop table extension in the elevated flat user workable position.
