A graphene heated seat cushion is a linen-faced pad with a honeycomb graphene heating film inside, powered by a 5V/2A USB power bank through a side pocket, with three levels selected by an LED button. The film sits under a breathable face and over a reflective layer and a dotted anti-slip base.
Three things decide whether a programme succeeds: what the power bank can supply, what the three levels actually mean, and whether the listing promises anything the cushion cannot do. This page covers all three, and it is deliberately specific about the second.
The cushion runs from a 5V power bank rated 2A or above, through the original charging cable. That single sentence carries more commercial weight than any other specification on the sheet, because it determines three things at once.
It sets the ceiling. A 5V/2A supply is a modest budget, and every claim about how fast the cushion warms has to live inside it. It also explains why the cushion is a seat warmer rather than a space heater — it is designed to put warmth into a small area you are already sitting on, not to raise the temperature of a room.
And it tells you what is not in the box. The power bank is not included. The reference material shows a person sliding their own power bank into the side pocket, and the safety note is explicit about using a unit rated 5V/2A or above with the original cable. For a retailer, this is the first thing to put on the listing — not in the small print.
The heating element is described in the reference material as a Graphene Heating Film arranged in a honeycomb matrix. The hexagon pattern is not decoration: it is how a flat film is divided into small, evenly distributed cells so that the whole seat surface warms rather than a hot spot in the middle.
Above it sits a breathable, wear-resistant linen weave; below it a thermal reflective base film that sends heat back up instead of letting it leak into the chair; and at the bottom a silicone dotted rubber base that grips the seat.
Between the film and the base there is also a flame-retardant insulation layer. We describe it as the reference material names it. We do not attach a certification to it — see the note on figures below.
The LED push button on the side cycles three levels, each with its own indicator colour. The reference material gives each level a plain-English purpose, and those descriptions are more useful to a buyer than a number would be:
| Level | Indicator | What the reference material says |
| High | Red | Maximum warmth for cold days |
| Medium | White | Cozy comfort for everyday use |
| Low | Blue | Gentle warmth for all-day comfort |
Two further behaviours are worth writing into a listing because they answer the question every buyer asks — will it get too hot?
Intelligent constant temperature. A built-in sensor holds the surface at a steady level rather than letting it climb. Auto overheat protection. If the temperature rises too far, heating stops automatically.
The reference material also quotes a Rapid 3s Fast Heat figure. We pass it on with two conditions attached: it is the figure quoted for the cushion at a 5V/2A supply, and it should be confirmed on your approved sample rather than printed as an unconditional promise.
Worth reading as a specification, because each layer answers a different objection.
| Layer | What it does |
| Breathable wear-resistant linen weave | Airflow through the face, so sitting for hours does not feel like sitting on plastic. The tight weave also resists pilling and snagging |
| Honeycomb graphene heating matrix | Even heat distribution across the seat area instead of a central hot spot |
| Thermal reflective base film | Sends heat upward toward the sitter and reduces loss into the chair |
| Anti-slip silicone dotted rubber base | Grips the seat surface so the cushion does not slide when you sit down or shift |
The side pocket hangs off the edge of the cushion and holds the power bank, with the cable running a short distance to the button. It is a small design decision that solves a real annoyance: a power bank loose on a chair gets sat on, dropped, or left behind.
The pocket is fabric, not a compartment inside the cushion. That is worth stating plainly — it means the power bank is visible and reachable, and it means swapping to a larger power bank is a thirty-second job rather than a rebuild.
How long the cushion runs is a function of the power bank you supply, not of the cushion. We do not publish a runtime, because we would be publishing a figure for a battery we did not ship.
The reference material labels this SEAT-ONLY HEATING, and the label is worth keeping.
The backrest does not heat. For a seat cushion that is the right choice: the area that gets cold against a hard chair is the seat, the back is usually against a backrest that already insulates, and putting a heating film in a back panel adds cost, weight and a second failure point for very little gain.
If a buyer needs a heated back as well, that is a different product and should be quoted as one.
The reference material carries a safety line, and it is the one to reproduce verbatim on a listing:
For your safety, avoid using the cushion while it is wet. Always use the original charging cable and power bank rated 5V/2A or above.
To that we add four operating rules.
This is a comfort product. It warms a seat. It is not a medical device, it is not a therapy device, and it makes no claim about back pain, joints, circulation or any other condition.
Four variables are open, and the reference material shows all four with worked examples.
| Variable | Options shown |
| Brand logo | Woven label or silk screen |
| Dimensions and thickness | Width, depth and thickness set to your requirement |
| Fabric colour | Heather Grey, Beige, Charcoal, Navy, plus other colours and textures |
| Retail packaging | Custom printed box |
The commercial terms shown are low MOQ and factory direct / direct sourcing. For a first order, the sequence that usually works is: pick a colourway and a logo method, approve a sample at the intended supply, then scale.
Heather Grey is the reference colourway in this material, and it is the sensible default for a first run — it reads as furniture rather than as an accessory, which matters for office and dining chairs.
If a figure is a hard requirement for your programme, raise it at the sample stage and it becomes a defined, testable specification.
Dongguan Sheerfond New Material Co., Ltd. develops and manufactures far-infrared and graphene heating materials, and designs the heating systems built around them. Our low-voltage range covers 3.7 V, 5 V, 12 V, 24 V and 36 V architectures, and this cushion sits in the 5 V family: a power-bank product aimed at chairs people already own. Products are manufactured against project specifications with batch inspection records.
Send us the colourway, the logo method, your dimensions and thickness, the packaging, your target quantity and your market. If you are matching an existing chair range, send the seat dimensions and we will work from those.
Price indication: quoted per project, because the colourway, dimensions, logo method, packaging and order size all move the number.

Does it come with a battery?
No. The power bank is not included. Use one rated 5V/2A or above with the original charging cable.
How long does it run on one charge?
That depends entirely on the power bank you use, which is why we do not quote a runtime.
How hot does it get?
There are three levels — High, Medium and Low — described by purpose rather than by a temperature. We do not publish a degrees figure.
Is it safe to sit on all day?
The cushion has intelligent constant temperature and automatic overheat protection. Keep it dry, do not cover it with a thick seat cover, and disconnect it when you leave.
Can it get wet?
No. It is not waterproof. Avoid using it while wet, and dry it fully before reconnecting power.
Does the backrest heat too?
No. It is seat-only heating by design.
Can I put my own logo on it?
Yes — woven label or silk print, with custom colours, dimensions and packaging.
This product is a comfort product and is not a medical device. It is not intended to diagnose, treat or prevent any disease, and it makes no claim about back pain, joints, muscles, circulation or any other condition. It is not waterproof and not water-resistant: avoid using the cushion while it is wet, keep it dry, and dry it fully before reconnecting power. Always use the original charging cable and a power bank rated 5V/2A or above; the power bank is not included. Do not leave the cushion running unattended for long periods; do not cover it with a thick seat cover while heating; keep the power bank clear of the seat gap. The heat-up figure quoted is that of the reference material at a 5V/2A supply and should be confirmed on the approved sample. Surface temperature, wattage, runtime, power bank capacity, dimensions and certification status are confirmed per project or per supplied power bank.
