The problem
Traditional upholstered chairs often retain heat, causing discomfort during warmer seasons. While add-on bamboo mats exist, they frequently slide out of place, lack structural integration with the chair frame, and offer limited durability at the edges. Users need a seating solution where the cooling surface is built into the furniture structure itself, ensuring stability and consistent contact without the hassle of loose accessories.
The solution
- The core innovation is a backrest (1) whose surface is covered with a bamboo mat fabric (2).
- This fabric consists of lateral bamboo chips sequentially connected in series along the longitudinal height (about 0.5-2 cm per chip).
- The fabric has two main layers: a cool seat layer (21) containing the bamboo chips and a reinforcing layer (211) made of woven bamboo cane bonded to the bottom of the chips.
- An extension layer (22) wraps around the sides of the cool seat layer. This extension includes a surface layer (221) at the edge and a bottom layer (222), which are sutured together to enclose the reinforcing layer.
- The entire assembly is fixedly connected to the backrest frame, either by binding (for wooden frames) or by pressing elastic rubber strips into molded grooves (for plastic/molded frames).
- Optional components include a cushion (3) and handrails (4), both topped with the same bamboo mat fabric (2).
- Removable inner pads (51, 52, 53) can be attached to the backrest, cushion, and handrails using fasteners like zippers, buckles, or velcro.
Who it is for
- Outdoor Furniture Brands: Companies manufacturing patio or garden chairs that need breathable, weather-resistant surfaces that stay cooler than synthetic fabrics.
- Office Chair Manufacturers: Makers looking to differentiate their product line with ergonomic, temperature-regulating seating solutions for summer use.
- Home Decor Retailers: Sellers offering premium home furnishings where natural materials like bamboo appeal to eco-conscious consumers seeking comfort and aesthetics.
- Hospitality Suppliers: Hotels and resorts needing durable, easy-to-clean seating for poolside or lobby areas where guests may sit for extended periods in warm climates.
How it works
The main parts
| No. | Part | What it does |
|---|---|---|
| 1 | Backrest | The primary structural component supporting the user’s back. |
| 2 | Bamboo Mat Fabric | The cooling surface composed of bamboo chips and reinforcing layers. |
| 21 | Cool Seat Layer | Top layer containing the lateral bamboo chips. |
| 211 | Reinforcing Layer | Woven bamboo cane bonded beneath the chips for strength. |
| 212 | Confining Layer | Sutures wrapping the side of the seat layer to hold layers together. |
| 22 | Extension Layer | Wraps around the fabric edges; includes surface (221) and bottom (222) layers. |
| 3 | Cushion | Optional seat pad, also covered in bamboo fabric. |
| 4 | Handrail | Optional armrest, covered in bamboo fabric. |
| 51-53 | Removable Pads | Inner cushions attached via zippers/buckles for comfort and cleaning. |
Assembly and Use
- Frame Preparation: The backrest (1) is manufactured, typically from wood or molded material. If molded, it features circumferential grooves.
- Fabric Construction: Lateral bamboo chips are strung together. A reinforcing woven bamboo cane layer (211) is bonded to their underside. An extension layer (22) wraps around the perimeter, enclosing the reinforcing layer within its sutures (212).
- Attachment: For wooden frames, the fabric is bound tightly to ensure the extension layer holds firm. For molded frames, the extension layer’s edge is pressed into the groove, using elastic rubber strips to create friction and secure fit.
- Adding Accessories: Optional cushions (3) and handrails (4) are prepared with the same bamboo fabric top. Removable pads (51-53) are inserted into pockets formed by the extension layer and secured with zippers or buckles.
- Usage: The user sits on the bamboo-covered surfaces. The natural material provides a cooler touch compared to cloth or leather. The removable pads allow for washing or replacement if the inner foam degrades.
Applications
Patio and Garden Chairs
Outdoor seating faces direct sunlight and high temperatures. The bamboo fabric dissipates heat better than polyester, keeping the chair surface cooler for users relaxing in gardens or patios during summer months.
Office Task Chairs
Workers spend long hours seated, often generating body heat. Integrating bamboo panels into the backrest and seat reduces sweating and discomfort, improving productivity and comfort in non-air-conditioned or warm office environments.
Poolside Loungers
Near pools, humidity and sun make synthetic materials sticky and hot. Bamboo offers a dry, cool texture that dries quickly after splashes, providing a comfortable transition from swimming to resting on lounge furniture.
Hotel Lobby Seating
Guests waiting in hotel lobbies may sit for varying durations. Bamboo-covered chairs provide a distinct aesthetic that signals luxury and nature while maintaining a comfortable temperature regardless of lobby climate control fluctuations.
Where it is less suitable
- High-Impact Industrial Settings: Bamboo chips can crack under heavy mechanical impact or rough handling typical in workshops or warehouses.
- Extreme Cold Climates: In very cold rooms, bamboo feels significantly colder to the touch than padded fabric, potentially causing discomfort unless paired with thick removable pads.
- Complex Curved Frames: The rigid nature of the bamboo chip fabric makes it difficult to conform to highly curved or irregularly shaped backrests without specialized cutting and fitting.

Claim 9 specifies the internal structure of the cool seat layer (21), which includes a reinforcing layer (211) bonded to the bottom of the bamboo chips, made of woven bamboo cane, and a confining layer (212) that sutures the side of the seat layer.
Claim 10 details the extension layer (22), consisting of a surface layer (221) at the edge and a bottom layer (222) covering the underside, bonded circumferentially, with the cool seat layer sandwiched between them and held by the confining layer.
This is a simplified reading for orientation only. The legal scope is defined by the exact claim wording in the official Chinese document.
What this means for US production
This patent was filed in China and has lapsed, so it no longer restricts anyone in China. The public record shows no US or other foreign counterpart.
Two points to settle early:
- Other patents may exist. Bamboo composite furniture and cooling seat technologies are active fields in the US. A freedom-to-operate (FTO) review is recommended to check for existing US patents covering specific bamboo processing methods or integrated cooling structures before mass production.
- Material sourcing. The quality of bamboo chips and the bonding agents used in the reinforcing layer affect durability. Supply chain verification is needed to ensure consistent material properties.

- Production - Mass manufacture frames; cut and assemble bamboo fabric; install pads.
Quantities & timeline
Tooling depends on the frame material: molds for plastic/composite frames, jigs for metal bending/welding. Bamboo fabric requires precise cutting and stitching stations. Lead times vary based on bamboo supply availability and finishing processes. Send us your frame specs, quantity, and target finish and we will reply with options.
Production notes
Tooling and process
The frame likely requires wood or MDF machining or steel tube bending and welding. The bamboo fabric assembly involves sewing the reinforcing and extension layers together. Bonding the chips to the backing needs controlled pressure and curing time.
Cost drivers
Costs are typically driven by fabric and foam grade for the inner pads, tube diameter and wall thickness for metal frames, and packaging volume due to the bulk of assembled chairs. Labor-intensive sewing and bonding steps also add cost.
Prototyping path
We would typically start with a 3D model and load path check. Build a welded or bolted frame sample to verify dimensions. Test the load test on the frame with the bamboo fabric installed to check for flex or breakage.
What we would change before tooling
We would likely adjust the joint design to ensure the bamboo fabric doesn’t slip. Refine the connector and bracket count to minimize visible hardware. Optimize the surface finish to prevent splintering at chip edges.
Common failure points
Watch for loose joints after repeated load if the frame is weak. Coating chips at edges may occur if the bamboo isn’t properly sealed. Stripped screws in particle board are a risk if mounting points aren’t reinforced.

Frequently asked questions
Is the bamboo fabric actually cooler than regular cloth?
Yes, bamboo has natural thermal properties that help dissipate heat. The patent describes using lateral bamboo chips on the surface, which allows air circulation and provides a cooler touch compared to solid upholstered fabric, especially in warm conditions.
Can the bamboo mat be removed for cleaning?
The outer bamboo fabric layer is fixed to the frame. However, the design includes removable inner pads (back cushions) that attach via zippers, buckles, or velcro. These pads can be taken off and cleaned, protecting the underlying structure.
How durable is the bamboo chip surface?
Durability depends on the bonding method and the quality of the bamboo. The patent includes a reinforcing layer of woven bamboo cane bonded to the chips to add strength. Proper sealing against moisture is essential to prevent cracking or warping over time.
Does it work with any chair frame?
The design accommodates different frame types. For wooden frames, the fabric is bound to the structure. For molded plastic or composite frames, the fabric edge is pressed into circumferential grooves using elastic strips. Metal frames would require custom attachment brackets.
What sizes are available?
The patent specifies bamboo chip heights of about 0.5-2 cm. Overall chair dimensions depend on the frame design you choose. We can customize the size of the backrest, cushion, and armrests to fit your specific furniture line.
Is it safe for outdoor use?
It can be used outdoors if treated properly. Bamboo is susceptible to moisture and UV damage. We recommend applying a protective sealant to the chips and using weather-resistant adhesives and backing materials to extend lifespan in outdoor environments.
Can this design be made and sold in the US?
The patent was filed in China and has lapsed, and the public record shows no US counterpart, so it does not restrict the design in the US or in China. However, other patents may exist in the field of bamboo furniture or cooling seats, so we recommend a freedom-to-operate check before volume production.
