Short answer
Bear says to avoid steam cleaners. Under 'Please avoid:' its help article lists 'Using steam cleaners, as excess moisture may damage foam materials,' along with soaking, harsh chemicals or bleach, and machine washing the cover. It recommends mild soap and cold water for small stains. Our dry-vapor method is our own, not a Bear exemption; check your warranty terms first.
Key terms used on this page
- Care instructions (manufacturer care guidance):
- What a manufacturer publishes about cleaning its product: a sewn-in label, a care web page, a help-center article or a brand blog post. They carry different weight. A sewn-in label or a product-care page speaks for a specific product; a blog post often gives general advice about many mattress types. On this hub we name the document type for every quote.
- Memory foam (viscoelastic foam):
- An open-cell, slow-recovery polyurethane foam that softens with body heat and conforms to pressure. Because its cells are open, liquid can travel into it, and because it is dense and insulating, it is slow to dry.
- Hybrid mattress:
- A mattress that combines a coil support core with substantial comfort layers of foam, latex or another material on top. What applies to a hybrid depends on what sits under the cover: the coils below or the foam or latex above.
- Dry-vapor steam:
- Steam made in a sealed, pressurized boiler and released through a hose and nozzle as hot vapor with a low liquid-water content. In the vendor specifications we reviewed, professional units are rated from 80 psi (Ladybug 2350) to 150 psi (Daimer), with stated boiler temperatures from about 345°F (Optima) to 360°F (Daimer); these are maker claims. Daimer describes its steam as about 5% water or less and Vapor Clean claims 'just 5-6% moisture'; that is a vendor claim, not an independent standard.
- Moisture load:
- The total amount of water a cleaning process puts into a mattress, whether from spray, steam condensate, shampoo or rinse. It is the main thing that decides how long a mattress takes to dry.
- Pass speed:
- How fast the steam tool moves across the fabric. A faster pass gives the fabric less time under the tool, so less heat and less condensed water reach any one spot. Purple's general guide makes the same point for home steamers: move 'without leaving it in one spot for too long.'
Bear sells foam and hybrid mattresses. It is one of five brands we checked whose official cleaning page mentions steam, and it tells owners to avoid steam cleaners. The reason it gives is moisture, not heat.

1. What the manufacturer actually says
The source is Bear's help-center article How do I clean a Bear mattress? (dated May 06, 2026 on the page; accessed 2 October 2026).
It covers Bear mattresses generally.
On routine care:
"To help keep your Bear mattress fresh and clean, we recommend routine maintenance and spot cleaning as needed."
On spot cleaning:
"Spot clean small stains with mild soap and cold water"
On drying:
"Allow the mattress to fully air dry before adding bedding back on"
Under "Please avoid:", the article lists:
"Using steam cleaners, as excess moisture may damage foam materials"
The same list also includes:
"Soaking the mattress with excessive water"
And:
"Using harsh chemicals or bleach"
And:
"Machine washing the mattress cover unless specifically stated otherwise"
2. Does it mention steam?
Yes. Under "Please avoid:", Bear lists "Using steam cleaners, as excess moisture may damage foam materials." The stated reason is moisture and the stated risk is damage to foam. We don't argue with that line or reinterpret it; it is Bear's instruction to owners.
3. Does it mention dry-vapor steam?
No. Bear's page never names dry-vapor steam. Its steam warning covers steam cleaners in general.
4. The restrictions it states
| Variable | What Bear's page says |
|---|---|
| Water | "Spot clean small stains with mild soap and cold water" |
| Soaking | Avoid "Soaking the mattress with excessive water" |
| Heat | Not stated |
| Steam | Avoid "Using steam cleaners, as excess moisture may damage foam materials" |
| Chemicals | Avoid "Using harsh chemicals or bleach" |
| Covers | Avoid "Machine washing the mattress cover unless specifically stated otherwise" |
Bear's list items are bullet fragments without periods on the page; we quote them as published.
Every brand's restrictions sit side by side in the compatibility guide.
5. How dry vapor differs from wet cleaning
Bear's stated reason for avoiding steam cleaners is that "excess moisture may damage foam materials."
Dry vapor leaves far less water than carpet-style extraction, but heat and moisture are separate variables.
Vapor Clean claims the Magnum XP runs at "just 5-6% moisture" (maker's claim, not our measurement).
The EPA advises drying wet materials within 24 to 48 hours; the hub's drying note explains why.
6. Sleep Sanitation's professional interpretation
This section is our view, not Bear's.
Bear's guidance is the default for owners: a protector, periodic vacuuming with an upholstery attachment, small stains spot cleaned with mild soap and cold water, full air-drying, and no steam cleaners, soaking, harsh chemicals, bleach or machine washing of the cover.
Our position: we can sanitize Bear mattresses (the CDC's sense, not disinfection). Bear names excess moisture as its reason, so moisture is what our technician manages most closely on a Bear: low output, quick repeated passes, no detergent, and time for the bed to air before it is made up. We don't present that as meeting Bear's instruction; Bear says to avoid steam cleaners, and that line stands.
We run three Italian-made Vapor Clean machines, the Magnum XP, ProV 350 and Pro6 Duo, at low steam output.
Passes stay quick and light. We don't unzip covers, soak the bed, or use bleach or solvents.
This is our method, not a Bear exemption, and Bear hasn't reviewed it. Check your warranty terms before booking.
We haven't found Bear warranty language about cleaning on the page we quote.
Not legal advice; if you're unsure, ask the manufacturer.
Bear's own cleaning routine
- Protector. "Use a mattress protector to help prevent stains and spills."
- Vacuum. Periodically, with an upholstery attachment.
- Spot clean. Small stains, mild soap and cold water.
- Dry fully. Before bedding goes back on.
- Rotate. Occasionally, if applicable.
Other care points on Bear's page
On routine care:
"To help keep your Bear mattress fresh and clean, we recommend routine maintenance and spot cleaning as needed."
Before a visit to a Bear bed
Bear is one of the few brands that names steam cleaners, and its reason is moisture: "excess moisture may damage foam materials." We take that seriously. Our position on a Bear bed rests on keeping moisture low and moving, not on any reading that Bear permits steam.
If you would rather follow Bear's page exactly, its own routine is vacuuming, spot cleaning and air-drying with a protector on, and that is a reasonable choice. If you book us, tell us the model; Bear sells foam and hybrid beds, and the comfort layers decide how cautious the passes need to be.
Bear's page also asks for routine maintenance, and that is where most of the benefit is. A Bear bed vacuumed periodically, with a protector washed on the same schedule as the sheets, rarely needs more than a spot clean. Our visit is for the build-up a household vacuum doesn't reach, such as dust in the seams and the sweat and skin that collect under a protector over a year or two.
After the visit, leave the bed uncovered until the surface feels dry to the hand. Bear's own spot-cleaning advice ends with air-drying, and we follow the same order: clean, then air, then make the bed.
Bear's list of things to avoid also includes harsh chemicals, bleach and machine washing the cover unless stated otherwise. None of those are part of our visit, and we'd suggest skipping them between visits too.
Common misreadings
"Dry vapor isn't a steam cleaner." Bear doesn't make that distinction, and we don't make it for Bear. Its page says to avoid steam cleaners.
"Bear's worry is heat." Bear's stated reason is moisture: "excess moisture may damage foam materials."
How Bear compares with the other brands we checked
Bear is one of five brands whose care pages mention steam. None of the 21 pages we checked mentions dry vapor.
Bear's page addresses 5 of the six variables in section 4; it is silent on heat.
Its water wording, for comparison: "Spot clean small stains with mild soap and cold water".
The compatibility guide lines up all 21 pages, from Tempur-Pedic's strict water rule to the brands that tie care to warranty.
Your label and warranty
Your sewn-in label speaks for your model and outranks Bear's web page. Use the hub's label checklist before any cleaning.
Where this fits
- Materials: memory foam, most moisture-sensitive materials.
- Related brands: Purple and Casper; the full table is in the compatibility guide.
- Visits: read our process, check pricing, or schedule a visit.
Related guidance and background
How other manufacturers word the same issue, for comparison:
- Saatva. "If you have a garment steam cleaner, go over your mattress with that before vacuuming" (Saatva).
- Avocado. "Steam cleaners are not recommended because their excessive heat can over-bake the organic latex" (Avocado).
- Tempur (UK). "Do not steam-clean or dry-clean the TEMPUR Material" (Tempur UK).
What we don't know
- How much moisture is excess. Bear doesn't quantify it.
- Bear's longer guide. The article links a longer blog guide that we didn't quote.
- Dry-vapor steam. Bear hasn't addressed it on the page we quote.
- Changes. Care pages change; we read Bear's page on 2 October 2026 and will update this page if it changes.
