Round Seat-Cushion Geometry with a Center Opening
This seat-cushion format has a round outline, a circular center opening and concentric seam or channel details. The displayed sample is black. The current dimension graphic publishes an approximately 40 cm outer diameter and 9.5 cm opening, subject to drawing, tolerance and sample confirmation.
The reference uses an integrated TPU outer surface and solid-gel interior, without a separate cover or fixing structure. It provides a cooling feel and cushioning and can be used directly, with optional chilling. Its central opening is a through-hole. Thickness, loaded behavior and chair fit require sample approval; no medical or pressure-relief outcome is established.
Published geometry and confirmation points
| Format | Round seat cushion with circular center opening |
|---|---|
| Displayed color | Black sample shown; production color to be confirmed |
| Published outer diameter | Approximately 40 cm; verify by approved drawing and sample |
| Published opening diameter | Approximately 9.5 cm; verify measurement basis and tolerance |
| Thickness and weight | To be confirmed |
| Surface, filling and seams | TPU outer surface and solid-gel interior; integrated construction without a removable cover. |
| Chair fit and retention | To be confirmed for the intended seat geometry and use environment |
| Care, labels and packaging | Wipe the surface to clean it; approve labels and packaging for the selected configuration. |
Approve the Opening, Thickness and Chair Together
Outer diameter alone does not define how the cushion sits on a chair. The drawing should record opening position, loaded thickness, outer-edge profile, seam/channel map and any underside or retention feature. Buyers should compare those points with the intended chair seat, front edge, backrest clearance and usable area.
If a pressure or thermal statement is required, define the production-equivalent sample, load, contact area, measurement locations, duration, ambient conditions and comparator. A center opening or gel label by itself does not prove pressure redistribution, cooling or a health outcome.
Sample Checklist for the Round Cushion
- Verify outer diameter, center-opening diameter, thickness, weight and tolerances.
- Confirm the exact surface, laminate or fabric, internal filling, seam/channel map and edge construction.
- Evaluate the unconditioned and loaded sample on the intended chair geometry.
- Inspect opening shape, surface condition, fill distribution, seam appearance and underside movement.
- Run only the pressure, thermal or durability methods defined for the project’s claim and acceptance plan.
- Approve care, inspection, warnings, labels, pieces per pack and carton configuration.
Customization and Quality Scope
Provide the intended chair drawing, target dimensions, construction, artwork and packaging through Cryozin’s customization process. Size, color, logo and pack format are reviewed for feasibility and approved on the sample; they are not guaranteed standard options.
The approved sample and specification can define checkpoints such as overall and opening dimensions, thickness, surface appearance, seam position, fill distribution, artwork, labels and pack-out. Cryozin’s quality-control process describes the workflow, not a product-specific test result.
Round Center-Opening or Tapered Solid-Outline Cushion?
| Selection point | Round center-opening format | Tapered solid-outline format |
|---|---|---|
| Outline | Round perimeter with central opening | Narrower top edge and continuous seat surface |
| Key drawing decision | Outer/opening diameter, thickness and channel map | Three-point outline, thickness and print placement |
| Fit review | Opening position and round footprint on the intended chair | Tapered outline against the intended chair edges |
| Artwork | Typically a surface or package decision | Printed surface can be a primary visual decision |
Keep the two geometries as separate product entities. Do not select either format on the basis of an unsupported medical or cooling promise.

Send the intended chair dimensions, destination market, target outer and opening diameters, thickness, construction, retention concept, claim targets, artwork, packaging and document requirements. Review the cold gel cushion category and Cryozin company information for additional sourcing context.
Product FAQs
Is the center opening a through-hole?
Yes. The reference cushion has an opening that passes through the cushion. Its behavior under a particular seated load should be checked on the sample; no pressure-relief outcome is established.
Is the ring air-filled, foam-filled or gel-filled?
It has a solid-gel interior and TPU outer surface. The material and use method are the same as the tapered cartoon cushion; the shape and printed appearance differ.
Does it need refrigerator preparation?
No. It can be used directly, with optional refrigerator preparation or use in an air-conditioned environment. It offers both a cooling feel and cushioning without a fixed-duration promise.
Is the cover removable for cleaning?
There is no separate cover. Wipe the integrated TPU surface to clean it.
Does the cushion include straps or a separate anti-slip base?
No. The reference has no fixing structure or separate anti-slip layer. Its material has a frictional feel; check the complete cushion on the intended seat.
What are the MOQ and sample lead time?
MOQ is assessed per product model. Confirm the applicable quantity for the selected dimensions and configuration in the quotation. Samples take 3–7 business days; regular production takes 18–25 business days. Custom projects can take longer, with timing confirmed individually.
