SEF · Sustainable Emergency Furniture
Beds, desks, chairs and partitions cut from recycled corrugated cardboard. They ship stacked like paper, fold into shape without tools, glue or training, and go back into the recycling stream when the emergency ends.

## The problem
Emergency response has an order of operations: water, food, medicine, a roof. Furniture never makes the list — and then the shelter opens. Classrooms in emergency schools run without desks. Clinics improvise without cots. Families in collective shelters sleep, eat and do homework on the floor, sometimes for months.
It is not that anyone forgets people need somewhere to sit and sleep. It is that conventional furniture is spectacularly bad at crossing into a crisis zone.
A steel-frame school desk is built to survive decades in one room. Every kilogram of that permanence has to be trucked over damaged roads and carried up shelter stairwells by hand.
An assembled bed frame is a large box of empty space. A truck that could carry bedding for a whole shelter carries frames for a corridor of it instead.
By the time institutional furniture is procured, shipped and cleared into a crisis region, the acute phase is often over — and the freight bill can exceed the furniture bill.
When a temporary shelter closes, its furniture becomes a disposal problem: too worn to redeploy, too bulky to store, too mixed-material to recycle.
## The approach
SEF furniture starts as a sheet of recycled corrugated cardboard and a cutting pattern. Every unit — bed, desk, chair, partition — is die-cut and scored flat, then folded into shape on site. The folds are not a compromise; they are the structure. Folding corrugated board along its scored lines turns a floppy sheet into box-section beams, the same principle that lets a cardboard box carry books.
Because the strength comes from geometry rather than fasteners, there is nothing to attach: no screws, no bolts, no adhesives, no tools, no assembly crew. Tabs lock into slots. An untrained adult follows the numbered folds printed on the panel itself, and the unit stands.
Because the material is corrugated board, everything else follows. The packs stack flat and dense on a pallet. One person carries several units at once. Local box plants near a crisis region can cut the same patterns from the same standard sheet stock — so production can move close to the need instead of shipping across it. And at end of life, the unit goes back into the cardboard recycling stream it came from.
Multi-wall recycled corrugated board — cheap, light, available on every continent, and already circular.
Scored fold lines that convert flat panels into load-bearing box sections. Geometry does the work fasteners usually do.
Fold-and-lock, in numbered order, printed on the panel. Design target: under four minutes per unit, first attempt, no training.
Flat packs a few centimetres thick that stack by the dozen on a standard pallet and travel as dense cargo, not shaped air.
Fully recyclable in the ordinary cardboard stream. A closed shelter leaves behind bales of paper, not a landfill of frames.
## The material
Corrugated board is two flat liners with a fluted paper wave glued between them — a miniature truss that is nearly all air by volume and surprisingly stubborn in compression along the flutes. SEF structural panels use multi-wall board: two or three fluted layers laminated together, cut so that the flutes run the direction the load does.
The board is made from recycled fibre, and it is a commodity: the same sheet stock is produced by box plants on every continent, to well-understood grades, on machinery that already exists near almost any crisis region. That ubiquity is a feature we design around, because it is what makes local production licensing realistic rather than aspirational.
Multi-wall board with flutes aligned to the load path, used for bed decks, desk tops and chair shells.
A moisture-resistant coating on wear surfaces handles spills, wiping down, and humid indoor air. It is a coating, not a promise of waterproofing — we say so plainly in every product sheet.
Assembly steps, tab letters and care notes are printed directly on the panel in pictograms and short text, so the instructions cannot be separated from the furniture.
No screws, staples, plastic clips or laminate films. What arrives as one material leaves as one material, which is what makes the recycling claim true rather than decorative.
## Assembly
There is no booklet to lose and no video that assumes a phone, a signal and a language. The numbered steps are printed directly on each panel, in pictograms first and words second. This is what they say, in full, for the bed:
$ sef assemble SEF-BED-01 # one flat pack, one person, no tools · timer starts now 1. lay the pack flat, printed side up # 0:00 2. fold along the scored spine until it clicks 3. raise both side walls until they stand square 4. fold tabs A–D inward until each one locks 5. press the deck down until every lock seats 6. push down hard, twice, to check # target < 4:00 ✓ standing · no tools used · no glue used · no training needed
Every unit in the line follows the same grammar: fold the spine, raise the walls, lock the tabs, press to seat. Someone who has assembled one SEF piece has effectively assembled them all — which matters when the people setting up a shelter are its residents.
Disassembly is the same steps in reverse. A unit folds back flat for storage, redeployment to another site, or the recycling bale.
## Product line
A bed to sleep on, a desk to learn at, a chair to sit on, a partition to give a family a wall of its own. Each ships flat, folds up the same way, and folds back down when it is done.
SEF-BED-01
folded ≈ 7 cm · standing 190 × 90 × 30 cm
A raised sleeping platform that gets people off cold, wet or crowded floors. The folded deck forms parallel box beams, so load spreads across the full frame.
SEF-DSK-01
folded ≈ 5 cm · standing 110 × 55 × 70 cm
A two-pupil classroom desk for emergency and temporary schools. A stable writing surface is the difference between a room with children in it and a classroom.
SEF-CHR-01
folded ≈ 4 cm · standing 42 × 42 × 78 cm
A single chair with a backrest — for eating at a table, waiting at a clinic, sitting through a lesson. The most ordinary object in the line, and the most missed.
SEF-PRT-01
folded ≈ 4 cm · standing 3 panels × 60 cm, h 180 cm
A free-standing folding wall. In a collective shelter, a partition is not decoration — it is a changing room, a nursing corner, a family's front door.
About the numbers on this page. Dimensions and load figures are current design targets from our workshop prototypes, stated as targets on purpose. We will publish measured, independently load-tested figures with each product sheet as testing completes — and nothing before. SEF does not publish numbers it has not measured.
### Response kits
Procurement rarely thinks in chairs; it thinks in classrooms, family spaces and triage bays. Kits bundle the line into one line item per room, with the pallet maths already done.
Furnishes one temporary classroom for 24 pupils.
Turns one family's corner of a collective shelter into a room.
A six-cot ward bay with screening and a work point.
Kit contents are configurable — these are the starting manifests we quote from. Every kit ships flat on shared pallets and carries the same printed assembly steps on every panel.
## Logistics & impact
Humanitarian procurement is a logistics problem wearing a furniture costume. What decides whether a shelter gets furnished is rarely the unit price — it is pallet positions, kilograms per stairwell, customs weight classes, and what happens to the material afterwards. SEF is designed backwards from those constraints.
Every alternative material buys durability the situation does not need and pays for it in weight, cost and disposal. A shelter bed does not need to last thirty years; it needs to exist this week, hold up for the months it is needed, and disappear cleanly afterwards. Recycled corrugated board is the one structural material that is simultaneously cheap, light, printable, locally produced on every continent, and already inside a global recycling loop.
Sustainability here is not a certificate stapled on at the end. The unit is made of recycled fibre, ships with a fraction of the freight of conventional furniture, can be produced near the need instead of shipped across the world to it, and leaves as raw material for the next sheet.
## The lifecycle
A SEF unit's whole life is a loop, and every stage is deliberately boring: standard sheet stock, standard cutting machinery, standard pallets, the ordinary recycling stream. The only unusual moment is the four minutes in the middle where a flat pack becomes a bed.
1 OrderAn agency, NGO or municipality names the rooms — kits or units — and gets pricing and pallet maths back with the product sheets.
2 CutPatterns are die-cut and scored from recycled multi-wall board — at our production partner, or at a licensed box plant near the response.
3 PalletisePacks stack flat and dense. A pallet is a wing of beds or a classroom of desks, wrapped and labelled by kit.
4 ShipOrdinary palletised freight, no special handling. Locally cut orders may skip this stage almost entirely.
5 AssembleStaff and residents stand the units up themselves, following the steps printed on each panel. No tools, no crew, no waiting.
6 UseDaily service for the working life of the shelter. Worn units are swapped for the cost of cardboard; folded spares store flat in a corner.
7 RecycleWhen the shelter closes, units fold flat and leave as baled fibre for the next sheet — the loop closes where it started.
## Design principles
Each product in the line, and every future one, is checked against the same short list before a pattern is released. If a design needs an exception, the design is wrong.
01 Logistics firstThe unit is designed backwards from the pallet, the truck and the stairwell. If it ships badly, it does not matter how well it sits.
02 Geometry over hardwareStrength comes from folds and closed sections, never from fasteners. Anything that needs a screwdriver has failed the brief.
03 Honest materialCardboard is presented as cardboard — its limits stated in the product sheet, not discovered in the shelter. No figure is published before it is measured.
04 Producible anywhereEvery pattern must be cuttable from standard sheet stock on standard box-plant machinery, so production can move to the need.
05 Dignified by defaultA bed off the floor, a wall of one's own, a desk that takes a lesson seriously. Emergency furniture is still furniture for people.
## Who it's for
SEF sells to organisations, not households. If your job is to stand up a shelter, a school or a clinic at short notice, this line was designed around your constraints.
Framework-friendly: a small SKU set, per-unit and bulk pricing, dense pallet maths for freight planning, and full material declarations for procurement review. We speak logistics first and adjectives second.
Small orders are real orders. A single classroom of desks and chairs, or beds for one shelter wing, ships as ordinary palletised cargo and is assembled by your staff and residents the day it arrives.
Flat packs store for years in a fraction of a warehouse bay, ready before the emergency instead of procured during it. Preparedness stock that costs little to hold and nothing to dispose of.
Local production licensing. For sustained responses, shipping cardboard across the world defeats the purpose. We license our cutting patterns and quality specifications to capable box plants near the crisis region, so units are produced local to the need — faster, cheaper, and with the freight taken out of the equation. Ask about licensing.
## Where we actually are
SEF is an early-stage startup incubated at An-Najah National University's Innopark in Nablus, founded in 2026. The product line exists as working workshop prototypes; load testing and pilot conversations are in progress. We would rather tell you that plainly than imply a deployment history we do not yet have.
What we will publish, as it becomes true and checkable: measured load-test results per product, assembly times demonstrated on video by first-time assemblers, and — with partners' permission — units deployed and shelters furnished. Until then, those numbers stay off this page.
We come from a region that knows displacement first-hand. Emergency response is not an abstract use case here; it is the neighbourhood's reality, and it is the standard the product is being built to.
