Cut mattress like — Cutting up an old mattress for disposal can save the cost of pickup. Our team’s guide to safely dismantling a mattress at home — plus when to leave it to professionals.
James on our team cut up an old queen mattress in 2023 to fit it into a hatchback for a tip run. Took 90 minutes, made a mess of the garage, and saved $80. Here’s the proper way.
Should you do this at all? (Cut mattress like)
Cutting a mattress is worthwhile if: a) you have transport that can’t fit a whole mattress, b) the tip charges by volume not weight, or c) you’re recovering specific materials (the steel springs are scrap-metal valuable). It’s NOT worthwhile if your council does free mattress pickup or a brand take-back is available — see our mattress recycling guide.
Tools you’ll need
- Stanley knife or sharp utility knife (with spare blades — they dull fast)
- Heavy-duty wire cutters (for the springs)
- Work gloves (springs cause cuts; foam isn’t fun on bare hands)
- Dust mask (mattresses release fine fibres when cut)
- Drop sheet or large tarp
- Bin bags (heavy duty)
Step-by-step
- Lay the mattress flat on a tarp outdoors. Garages work too if you don’t mind sweeping.
- Cut around the perimeter. Slice through the side fabric, all the way around. The top fabric will lift off.
- Peel back the cover. Underneath is usually quilted padding — pull or cut this off in sections.
- Remove the foam layer. Cut into manageable strips, roll up, bag separately. Foam is bulky but light — fits surprisingly small once compressed.
- Expose the spring unit. Cut the side wires and the perimeter rod with wire cutters. The individual coils will release.
- Bundle the springs. Bind into 3–4 manageable bundles with wire or strong cable ties. The whole spring unit weighs around 11 kg in a queen.
- Bag the timber. The base frame is usually pine slats — these can go in normal recycling timber.
What to do with the parts
| Component | Disposal route |
|---|---|
| Steel springs | Scrap metal yard (small cash return) |
| Foam layers | Soft Landing if available; otherwise general waste |
| Cotton padding | Composting (natural) or general waste |
| Outer fabric | Upparel textile recycling or general waste |
| Timber slats | Council green bin or recycling yard |
Don’t do this with foam-only mattresses
If the mattress is pure foam (no springs), cutting it up is unnecessary — it can usually be folded or rolled into a normal car. Save yourself the dust.
Safety
Wear gloves. Be careful with the wire cutters — coil ends are sharp. Don’t breathe in mattress dust. Ventilate the space afterwards.
