Direct Answer: A clean, dry mattress can usually be dropped off free at a participating California recycling site. A wet, torn, soiled, or infested one gets rejected and becomes landfill waste billed by weight.
The new bed showed up, the delivery crew left, and now the old mattress and box spring are leaning against the garage wall. The metal frame came apart with a socket wrench and a few minutes of patience, and it is already sitting in a tidy pile of rails and bolts.
The frame was the easy part. The mattress is the part with rules, and most people in Hollister and Gilroy do not find that out until a truck is already in the driveway or they are standing at a gate getting turned around.
I want to walk you through those rules plainly: why free mattress disposal exists in California, the one condition problem that quietly turns free into expensive, and the point where hauling it yourself stops making sense.
Why a mattress follows different rules than the bed frame
That metal frame is scrap. It rides in a mixed load with everything else from the bedroom and gets sorted at the yard with no special handling.
A mattress is a different animal. It is a layered mix of steel springs, foam, felt, and fabric, and those layers have to be cut apart before any of it has value. Loose mattresses also jam up landfill compactors, which is why disposal sites treat them as their own category.
California set up a statewide mattress stewardship program to deal with that. It is written into state law, certified by CalRecycle, and run by a nonprofit council, and it is paid for by a recycling fee collected every time a mattress or box spring is sold in the state.
Two things follow from that:
- You already paid into the program when you bought the new bed.
- Participating collection sites accept mattresses and box springs at no charge from residents.
The catch is that free drop-off means you do the work. You need a truck or a trailer, straps, a second set of hands, and a trip during business hours. Sites also cap how many units you can bring per visit, so a whole-house load is not a drop-off plan. If you are weighing errand against pickup, our breakdown of free bulky pickup versus hiring a hauler covers the same decision for couches and appliances.
The condition rule that turns free mattress disposal into a landfill bill
Here is the part almost nobody tells you. Collection sites across California publish nearly identical condition language, and they turn units away at the gate.
A mattress or box spring is commonly rejected when it is:
- Wet or soaked through
- Severely torn, cut open, or missing material
- Twisted, bent, or crushed out of shape
- Soiled with bodily fluids, mold, or heavy staining
- Known or suspected to have bed bugs
Once a unit is rejected, it stops being recyclable material and becomes ordinary landfill waste, which is billed by weight. A soaked king mattress and box spring can put on a shocking amount of water weight, and you pay for every pound of it.
Now tie that to our weather. December through February is the wettest stretch in Hollister, with December averaging somewhere around 63mm of rain across roughly 11 rainy days. A mattress parked in a side yard or an open carport in October is almost certainly going to fail the condition test by January.
So the single most useful thing I can tell you is this: a dry mattress has free options, a soaked one has expensive ones. If it is sitting outside right now, move it into the garage, get it off the ground on a pallet or scrap lumber, and wrap it in a plastic mattress bag. A tarp thrown over the top is not enough, because water wicks up from the slab.
The local calendar worth putting on your phone
San Benito County residents have a free option that does not require a long drive. The county runs free quarterly Recycle Day events that accept mattresses, tires, and electronic waste along with household hazardous waste.
The next one is set for November 7, 2026, from 9am to 1pm at the Resource Management Agency lot on Technology Parkway in Hollister. A few details that matter:
- Proof of residency is required, so bring your ID
- The 15 gallon or 125 pound cap applies to hazardous material brought to the event
- It is a drop-off event, which means you load, you drive, and you unload
The county also holds household hazardous waste collection on the third Saturday of each month at the John Smith Road Landfill, 9am to 12pm. That one is aimed at paint, chemicals, and similar material rather than furniture, so call ahead before you load a mattress for it. You can confirm current dates and accepted items on the San Benito County collection event page.
Over in Gilroy, bulky item pickup runs through Recology South Valley, with its own annual limits and item rules. Check what your account actually includes before you set anything at the curb, because an uncollected mattress at the curb is how illegal dumping citations start.
Will your mattress be accepted or rejected?
This is the quick gut-check I run through before anybody loads a mattress into a truck.
When the math flips: multiple beds, rentals, and estates
One mattress is an errand. Five mattresses plus box springs, a couch, and a garage full of boxes is a load, and a load is a different kind of job.
Free drop-off works beautifully for a single bed. It falls apart fast when you are:
- A landlord turning a three or four bedroom rental between tenants
- An adult child clearing a parent’s home with beds in every room
- A family moving out and running against a close of escrow date
- A property manager who needs a unit empty before Monday
Per-visit unit caps mean several trips. No truck means borrowing one. Stairs and tight hallways mean you need help you probably do not have on a Saturday morning.
Most of the whole-property work we do looks exactly like this. One customer summed up a typical version of it: “We rented a 25 yd dumpster to tackle our garage and backyard clean-up.” Our containers come in 10, 15, and 25 yard sizes, and rentals start at $500 for a 2 day rental, though the right size and the final number depend on what you are clearing and how long you need it. Full-service pickup is priced by volume instead, so ask for a quote on both and compare.
If you do call for a pickup, knowing what information gets you booked faster will save you a round of phone tag.
Four ways to get rid of a mattress on the Central Coast
Here is how the real options stack up for homeowners in Hollister, Gilroy, and the Monterey County communities we cover.
| Option | Best for | What it costs you | The catch |
|---|---|---|---|
| Participating recycling drop-off site | One or two clean, dry units | Free, plus your time and fuel | You load and unload; per-visit unit limits apply |
| County quarterly Recycle Day | Hollister residents with a truck | Free with proof of residency | Set date and a four hour window; next one November 7, 2026 |
| Curbside bulky pickup | Households within their annual item limit | Usually included in service | Item caps and condition rules; confirm before setting it out |
| Hauler pickup or a rented container | Multiple beds, rental turnovers, estates | Priced by volume or container size | Costs money, but no truck, no trips, no lifting |
What actually happens to your mattress after we load it
The question I get most often is not about price. It is some version of “where does this end up?”
When a mattress comes out of a mixed load, it does not ride to the landfill with the broken patio furniture. We pull mattresses and box springs out and keep them separate, because once they are buried under drywall scrap in the back of a truck they get crushed and soaked and lose every option they had.
From there it is simple:
- Condition passes: the unit goes to a recycler where the steel, foam, felt, and wood get separated and sold back into the supply chain.
- Condition fails: it goes to the landfill as bulky waste and gets billed by weight, and we tell you that before the truck leaves, not after.
Appliances and electronics in the same load follow their own separate paths, which is why a dead fridge costs more to haul than a couch even though the couch is bigger. If you are clearing a whole bedroom at once and wondering where each piece goes, our guide to sorting post-holiday loads breaks down the same logic item by item.
The only thing I would ask you to do before any of this is keep it dry. Everything else is negotiable. Water is not.
Frequently Asked Questions About Mattress Disposal
Can I just throw a mattress in a rented dumpster?
Sometimes, but tell us before the container drops. Mattresses are often charged separately at the transfer station because they have to be pulled out of the load by hand, so it changes the math. On a big cleanout we would usually rather load the beds onto the truck and leave the container for everything else.
Does the box spring follow the same rules as the mattress?
Yes. Box springs and foundations count as their own unit under the state program, so a queen set is two units toward any per-visit cap. The same condition rules apply to both.
What if the mattress might have bed bugs?
Say so upfront. Infested units are rejected by recycling sites, and the right move is to bag and seal it where it sits before anybody carries it through the house. We handle disposal, not treatment, so if the problem goes beyond the bed you will want a licensed pest professional for the rest of the home.
How much does it cost to have a mattress hauled away?
It depends on how many units there are, where in the house they are, and what else is going with them. A single mattress pulled from a garage is a very different job from six units carried down a staircase, and pricing for Hollister, Gilroy, and Monterey County jobs is quoted by volume. Call for an estimate before you commit, and we will tell you if a free drop-off makes more sense for your situation.
Do I need to remove the plastic bag before drop-off?
Usually not, and the bag is what keeps the unit dry enough to be accepted in the first place. Leave it wrapped until it is out of your hands.
Clearing more than one bed?
If you have a single dry mattress and a free Saturday, take the errand and keep your money. If you are looking at several beds plus a garage, an estate, or a rental turnover anywhere from Hollister and Gilroy down through Salinas and Monterey County, that is a load, and loads are what we do.
