The Short Answer: It Depends on the Dumpster
Can you throw a mattress in a dumpster in Denver? Here’s the breakdown:
- Your apartment/condo dumpster: Almost always NO. Most property management companies and waste haulers prohibit mattresses in shared dumpsters. They’re bulky, they block compactors, and haulers charge property managers $50-$150 per mattress found in the dumpster.
- A rented roll-off dumpster: It depends on the company. Some Denver dumpster rental companies accept mattresses; others ban them or charge a $25-$50 surcharge per mattress. Always ask before renting.
- A construction dumpster: Usually NO. Construction dumpsters are for construction debris only. A mattress contaminates the load.
Why Dumpster Companies Don’t Want Mattresses
Mattresses cause problems at every stage of waste processing:
- They don’t compact — Springs and foam resist compression, wasting truck and landfill space
- They jam equipment — Springs wrap around compactor and sorting machinery, causing costly breakdowns
- They take up disproportionate space — A single king mattress takes up the same dumpster space as 20+ trash bags
- They’re heavy when wet — A rain-soaked mattress can weigh 100+ lbs, adding weight overage charges
This is why many states (California, Connecticut, Rhode Island) have banned mattresses from landfills entirely. Colorado hasn’t passed a mattress recycling law yet, but the waste industry discourages mattress disposal in dumpsters regardless.
What Happens If You Put a Mattress in Your Apartment Dumpster?
If your building’s waste hauler finds a mattress in the dumpster:
- The hauler charges your property manager a contamination fee ($50-$150)
- Your property manager passes the charge to you (if they can identify who did it)
- You may receive a lease violation notice
- Some buildings deduct the fee from your security deposit at move-out
It’s not worth it.
7 Better Ways to Get Rid of a Mattress in Denver
1. Denver Large Item Pickup (Free)
Schedule a free pickup through Denver’s large item program. Mattresses qualify. Limit: 5 items + 10 bags per pickup. Wait time: 2-8 weeks.
2. Donate It (Free — If Clean)
Mattresses in good condition (no stains, tears, odors, or bed bugs) can be donated:
- Denver Rescue Mission
- Salvation Army (condition requirements are strict)
- Habitat for Humanity ReStore
3. Retailer Take-Back (With New Purchase)
Buying a new mattress? Some retailers offer haul-away:
- Denver Mattress / Furniture Row — Details here (policies vary)
- Casper, Purple, Tuft & Needle — Some online brands coordinate removal with delivery
- Costco — Free haul-away with mattress delivery
4. Mattress Recycling
Mattresses are up to 90% recyclable — steel springs become scrap metal, foam becomes carpet padding, cotton becomes industrial rags. Denver-area recycling options:
- Spring Back Colorado — Mattress recycling program
- Some transfer stations accept mattresses for recycling (call ahead for current policies and fees)
5. Professional Junk Removal ($99)
At Junk Same Day, mattress removal starts at $99 and includes:
- We come inside and carry it out (any floor, any stairs)
- Same-day pickup available
- We recycle mattress components when possible
- Box spring included at the same price
6. Haul It Yourself ($30-$60)
Take it to a transfer station:
- Denver Arapahoe Disposal Site — 3500 S. Gun Club Rd, Aurora
- Tower Landfill — 8480 Tower Rd, Commerce City
You’ll need a truck or van and someone to help carry it. Fees: $30-$60 per load.
7. Curb Alert (Risky)
Posting "free mattress — curb pickup" on Craigslist sometimes works. But if nobody takes it, you’re responsible for removal — and leaving it on the curb is technically illegal dumping ($150-$999 fine).
What About Box Springs?
Same rules apply. Box springs have the same disposal challenges as mattresses (bulky, springs jam equipment). The good news: when you hire us, we take the mattress and box spring together for the same minimum price.
Mattresses and box springs both leave on one visit when you book junk removal in Denver, with no dumpster rental to schedule around.
