Set 70842 Emmet's Triple-Decker Couch Mech
The LEGO Movie II

Emmet's Triple-Decker Couch Mech

Emmet's Triple-Decker Couch Mech 70842 turns a piece of furniture into a walking robot, straight out of a running gag in The LEGO Movie 2 where Emmet builds mechs from whatever is lying around. The set comes with 312 pieces and 3 minifigures, enough to build a small scene rather than a single vehicle. Its 72 unique parts lean towards broad flat surfaces, fitting for a sofa-shaped machine.

Description

Piece efficiency for a specific shape

72 unique parts across 312 total pieces is a fairly low variety for a set this size, and that tracks with what the model actually needs: large flat panels for the couch cushions plus a compact leg mechanism, rather than the fine detailing a building would require. That keeps the build quick without feeling thin, since the repeated panel sections come together fast once the pattern is established. Builders looking for a short, satisfying session rather than a multi-day project will likely finish this one in a single sitting.

A specific scene, not a generic mech

Rather than an original vehicle design, this set recreates a specific gag from The LEGO Movie 2, where Emmet turns household furniture into makeshift mechs mid-adventure. That makes it a more direct film tie-in than sets built around generic mechs or vehicles, which matters for anyone collecting pieces tied to specific scenes rather than just the wider theme. The legs are built to hold a standing pose, letting the couch read clearly as a walking machine rather than furniture with wheels bolted on.

Grey, brown and a blue accent

Dark bluish grey, light bluish grey, reddish brown and medium blue reproduce the couch's actual upholstery and frame colours rather than a typical vehicle palette. The parts list on this page shows exactly how many pieces come in each colour, which is worth checking before you build if you are planning to repaint or recolour sections, or simply want to know how much of the grey is reusable in other projects.

Room for a full scene

With 3 minifigures included, there is enough here to stage a small scene around the mech instead of just posing a single vehicle, which suits anyone recreating moments from the film or inventing their own stories around Emmet's improvised builds. The full parts list on this page lays out all 72 unique parts and colours in advance, useful for checking exactly what to expect before adding this set to a Movie 2 collection.
