Which one should you build?

Four designs, four jobs. Here is the honest way to choose.

Decision in one question: where do you work?

On jobsites, in clients’ homes, out of a van → MFTC. It’s a complete portable workshop: folds to under 50 cm, rolls like a hand truck, carries 4 Systainer drawers, unfolds into an MFT-height worktable with optional extension tables for full sheets.
Light and mobile — you carry your tools in a Systainer stack → MFTB. It locks on top of your Systainers and gives you a clamping-ready mini bench anywhere, at a comfortable height.
In your own shop, building furniture start-to-finish → MFSC. One cart that is successively a parts cart, a height-adjustable workbench (62–90 cm), an assembly table, a glue-up station and a drying rack.
Setting up a permanent shop → System Workshop. The bench-and-cabinet wall everything else docks into.
All of the above / building over time → Combo Pack, the bundle.

Common combos

Most professionals end up with MFTC for the site + MFSC (often two) for the shop. The MFTB is the natural add-on if you already live in the Systainer system. That’s exactly what the Combo Pack is for.
