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: 4 items per cycle. 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 — 5500 Quebec St
- Tower Road Transfer Station — 9900 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.
