Common materials include metal frames and wood-based tops. Tops are often made from MDF (medium‑density fiberboard) or other wood composites, paired with metal or composite frames.

Many smaller black laptop and tray tables are lightweight and fold flat for easy storage and transport. Product descriptions and reviews commonly note folding‑flat designs that make them simple to carry and store.

Adjustable features commonly include multiple height settings and tilting tabletops for laptop trays. Standing desks often offer electric height adjustment with memory presets; some tray tables also include cup holders or angled surfaces.

Some standing desks include integrated power and accessory features such as standard outlets and USB ports, cable‑management holes, large mouse‑pad areas, and hooks or pockets for headphones and supplies.

Black desks are commonly marketed for bedrooms, living rooms, home offices, study rooms, and other small spaces such as dormitories.
