How to get rid of a mattress in Castle Rock, CO.

Policies vary by branch. Call before you carry one over — we asked each of the big three directly: Goodwill, the Salvation Army and Habitat for Humanity.

• Castle Rock runs no trash collection at all, so there is no town bulky-item or mattress pickup to book. The Town's Other Services page states plainly: "The Town does not provide trash removal or recycling services. Neighborhoods with homeowners associations may provide trash removal through the HOA." Households outside an HOA arrange their own service; the page names HBS Trash and Waste Management as companies serving the area. The only Town-adjacent recycling the page describes is a volunteer-run drop-off: "A community recycling center operates from 10 a.m. to noon every Saturday at 701 Prairie Hawk Drive." It also notes the Douglas County Slash/Mulch site, which "accepts tree branches, leaves, grass clippings and other yard debris year-round from 8 a.m. to 5 p.m. Monday through Saturday". Neither takes mattresses, and no free allowance, per-item fee or booking line for bulky waste exists because no Town program exists. Source Not confirmed: The Town does not publish what any of the named haulers charge for a bulky item or a mattress. Not confirmed: The Saturday community recycling center's accepted-materials list is not given on this page beyond the Town's FAQ wording of a "paper, glass, aluminum, plastic, and tin recycling program"; the operator is not identified. Not confirmed: Whether HOA contracts in Castle Rock include any bulky-item allowance is not stated anywhere on the Town site.
• The Town's Clean up resources page is its full published answer on where to take unwanted household items, and it offers no mattress drop-off. The recycling section lists Douglas County GreenWorks (303-660-7480) for "Slash-mulch and green yard waste", "Open year-round from 8 a.m. to 5 p.m. Monday through Saturday", with loads to be covered on arrival and free wood chips available; free year-round electronics recycling at 5675 Delva Way, Sedalia through Douglas County's program; PaintCare drop-offs limited to 10 gallons or less; and the Douglas County Household Hazardous Waste Collection Program, "one collection appointment per calendar year, $30 fee", administered by Waste Management, with a matching Waste Management At Your Door household pickup at $30 for which "Douglas County residents are eligible for one collection per calendar year". The page carries the disclaimer "The Town of Castle Rock does not endorse any organization or service named on this list but offers this list as a helpful resource." No landfill, transfer station or convenience center that would take a mattress is named on it. Source Not confirmed: The Town page names no landfill at all, so the nearest general disposal site has to be taken from the Douglas County page rather than from the Town. Not confirmed: No proof-of-residency rule is stated for the GreenWorks yard waste or electronics sites on this page.
• Not an option: Castle Rock's main local charity shop will not take a mattress, which saves the trip. Treasures Thriftique, the thrift store of the Help & Hope Center, is at 1638 Park Street, Castle Rock, CO 80109, taking donations Monday through Friday 9 a.m. to noon and Saturday 9 a.m. to 2 p.m., closed Sunday. Its published NOT accepted list includes "Beds, frames, mattresses" and "Used bed pillows", alongside upholstered furniture, large appliances, broken or damaged items and strongly-smelling goods. It does take books, clothing, crafts, decor, electronics, games, housewares, jewellery, kitchen items, linens, media, shoes, small appliances, tents, tarps, tools, toys and vintage and collectible items. Donors with loads larger than a pickup truck are asked to email treasures@helpandhopecenter.org before dropping off. Source Not confirmed: The page does not say whether a brand-new, still-wrapped mattress would be treated differently. Not confirmed: No pickup service terms are published for large donations beyond the emailed advance notice.
• Castle Rock's residential property rules set a tight curbside window, which matters when a private hauler or HOA collection is the only route for a mattress. The Town's Maintaining your residential property page states: "Garbage containers may be placed next to a public roadway or alley for trash pick up for a period not to exceed 24 hours", and separately that "Any accumulation of rubbish, trash, or solid waste is not allowed." It also states that "Construction and landscape materials, debris, dirt, and any general solid waste are not allowed on any public right-of-way, street, alley, or easement" and that material must be kept on the owner's property rather than in the street. A mattress put out days ahead of a pickup, or left in the alley, breaches these rules. Source Not confirmed: No fine or penalty amount is published, and no municipal code section is cited for the container or accumulation rules. Not confirmed: The page says nothing about wrapping or bagging a mattress, and nothing about HOA or apartment restrictions.
