A practical walkthrough for building and fitting the official Folded Space insert for Frosthaven, from punching foam trays to loading the box for faster setup.
Quick answer
Assemble the Frosthaven Folded Space insert by punching out the foam core trays, dry-fitting them empty in the box before loading any components, then filling each tray by category so you can lift them straight onto the table during play. The build takes an evening, not a weekend, but rushing the dry-fit step is the most common reason trays end up not fitting.
What the Folded Space insert actually solves
Frosthaven ships with a lot of cardboard and a lot of cardboard means long setup. The Folded Space insert is an official full-color foam core insert designed to keep the box as light as possible while giving every component a defined home. Because the trays are meant to be used during the game, not just stored, the payoff is measured in minutes saved at the start and end of every session rather than in shelf aesthetics alone.
Foam core behaves differently from wooden inserts. It is lighter, which matters when a fully loaded Frosthaven box already weighs a great deal, but it also means the trays are not structural. They hold shape well once assembled, yet they should not be used as a handle or stacked under heavy weight. Treating the insert as a lightweight organizing system rather than a load-bearing crate is the mindset that keeps it intact.
Before you start: workspace and expectations
Clear a table you can leave half-finished for a few hours. You will be working with flat foam sheets, punched-out tray pieces, and a growing pile of Frosthaven components that temporarily has nowhere to live. A second empty box lid or a large tray to hold loose tokens while you build keeps the process calm.
The insert is compatible with Frosthaven by Folded Space and is supplied as flat foam core sheets. Assembly does not require glue in most cases because the trays interlock, but a small amount of craft glue at high-stress corners is a reasonable insurance policy if you plan to move the box often. The catalog does not list a required adhesive or tool set, so treat any glue or knife as optional and decide based on how much you transport the game.
How to sequence the build so nothing gets loaded twice
The efficient order is: punch all trays first, dry-fit the empty tray layout in the box second, assemble the trays third, and only then load components. Loading components before the layout is confirmed is the single biggest source of rework, because you end up emptying trays to move them.
If you also own the Gloomhaven Folded Space insert, do not mix the two builds on the same table. The trays look similar at a glance, and the fastest way to create a fitting problem is to install a Gloomhaven tray in the Frosthaven box. Keep each insert's pieces in separate piles and label the piles if you are building both in one session.
Assembly and setup steps
- Punch every tray piece before assembling anything: Separate all foam core tray pieces from the flat sheets and lay them out by tray group. Foam core edges can fray if you tear pieces apart, so push them out steadily rather than yanking. Checkpoint: every tray group should have a matching base and walls before you start building.
- Dry-fit the empty trays in the Frosthaven box: Place the unassembled or loosely assembled trays into the box with no components inside. Confirm the lid closes and that no tray blocks another from lifting out. Common mistake: skipping this step and discovering after loading that one tray cannot be removed without emptying another.
- Assemble trays from the largest to the smallest: Build the big component trays first so you can confirm the footprint, then work down to small token trays that can be nudged into leftover gaps. Checkpoint: each tray should sit flat without rocking. If it rocks, a wall is seated incorrectly.
- Load components by how you play, not by how they ship: Group tokens, monsters, and cards into the trays you will actually pull onto the table during a scenario. The insert is designed so trays can be used during the game. Common mistake: sorting purely by component type and ending up with a tray you never lift out.
- Test a full setup and clear-away once: Run one scenario setup using only the trays, then pack everything back. Time both directions so you know whether the layout genuinely helps. Next step: if a tray slows you down, swap its contents with a neighbouring tray before your next session.
Product facts
- Frosthaven: Folded Space Game Insert: Official full-color foam core insert compatible with Frosthaven by Folded Space, designed for efficient storage and improved game play while keeping the box as light as possible. The lightness is a real advantage for a heavy campaign box, but it also means the trays should be lifted by their bases rather than squeezed at the sides.
- Frosthaven: Folded Space Game Insert: The trays can be utilized during the game and greatly aid set-up and clear-away times. Plan your tray layout around what you reach for most during a scenario, not around what looks tidiest on the shelf.
- Gloomhaven: Folded Space Game Insert: Official full-color foam core insert compatible with Gloomhaven Second Edition by Folded Space, designed for efficient storage and improved game play while keeping the box as light as possible. If you own both games, build and store the two inserts separately so similar-looking trays do not get swapped between boxes.
