Pool loungers can be designed to use material more efficiently by reviewing frame geometry and retaining only the support needed for stable, load-bearing performance. Adjustable backrests and stackable construction can remain part of the design, provided the finished structure meets the required capacity and stability checks.
The documented Roaona pool lounger has an aluminum frame, an adjustable backrest, stackable construction, and a stated capacity of 150 kg per seat. Its listed single-seat dimensions are 71 × 198 × 35 cm, while the double-seat model measures 140 × 198 × 35 cm. These details describe the product baseline, but they do not show that either configuration uses less material than another design.
The product information does not provide frame-member thicknesses, alloy grade, joint construction, comparative weight data, or strength-test results. As a result, it cannot identify a specific proven frame change or establish how much material could be removed while maintaining the stated capacity. Material reduction should be evaluated through design review and validation of the final configuration.
A practical assessment starts by comparing the existing frame with proposed geometry changes. Identify the parts and connections that carry loads, then review the updated design for support, stability, dimensional requirements, backrest operation, and stacking compatibility.
Kingwell states that it offers OEM and ODM customization, including CAD drawings, 3D designs, and changes to dimensions, colors, materials, and product details. These services can support an engineering review of a tailored design. They are not, by themselves, evidence of a particular material saving or certification of a modified lounger.
| Design area | Documented information | Check before reducing material |
|---|---|---|
| Frame | Aluminum | Confirm that revised members and joints provide the support and stability the project requires. |
| Seat capacity | 150 kg per seat | Verify that the final design retains the required load capacity. |
| Backrest | Adjustable | Check that the frame and adjustment mechanism remain stable across the adjustment range. |
| Storage | Stackable construction | Confirm that the updated geometry still stacks as intended. |
| Customization | Size, color, materials, and details can be customized | Review drawings and validate the selected configuration before production. |
Kingwell lists BS 5852 for outdoor furniture in the European region and EN 581 for outdoor tables in European countries. The supplied information does not show that these listed credentials establish compliance of a specific redesigned pool lounger with a strength requirement. A project case mentions the supply of more than 500 sun loungers for an American resort poolside area; this indicates project experience, not comparative structural performance.
No specific modification or quantified material saving is provided. The available specifications identify an aluminum frame and a capacity of 150 kg per seat.
Both features are listed for the product. The final design needs to be reviewed to ensure that structural changes do not prevent safe adjustment or practical stacking.
Listed applications include hotel and resort pools, beach clubs, and poolside areas. Kingwell also describes a resort project involving more than 500 sun loungers.
Use frame-geometry review to identify potential material efficiencies, while treating the 150 kg per-seat capacity, stability, adjustability, and stacking requirements as checks for the final design. Since the supplied specifications do not demonstrate a particular reduction, request a design review and confirm the finished configuration's performance before production.
