Mantis Desk

Samuel Wilkinson backed this solid ash desk with a note-board panel and hid the plugs in a tray beneath.

The Mantis Desk pairs a generous solid wood top — ash or stained walnut — with a white powder-coated steel frame, designed in Britain and crafted in Lithuania for Case Furniture. A removable plate opens onto a storage tray that swallows plugs and cables, alongside a small drawer and file holder, while the back panel doubles as a note board or privacy screen.

Common Questions

How does the cable management work?
A removable plate in the desktop opens onto a hidden storage tray where plugs, power strips, and slack cable live out of sight. A small drawer and file holder handle the rest of desk clutter.

Is it hard to move or ship?
No — the steel legs detach cleanly for flat-pack transport without weakening the structure. Two-person assembly is recommended when setting it up.

What is the back panel for?
Two things: it works as a note board for pinning reference material, and as a privacy screen that visually separates your workspace in shared rooms.
