When it comes to outdoor sofa comfort, armrest height plays a crucial role in ensuring relaxation and ergonomic support. The ideal armrest height typically ranges between 7 to 9 inches (18 to 23 cm) above the seat cushion, allowing your arms to rest naturally without straining your shoulders or wrists.

This measurement aligns with standard ergonomic principles, promoting proper posture while lounging. For deeper sofas or taller individuals, slightly higher armrests (up to 10 inches) may be preferable. Conversely, lower armrests work well for compact designs or petite users.

Material choice also impacts comfort—cushioned armrests at this height provide soft support, while wooden or metal frames should include padding for prolonged sitting. Always test armrest height with the actual seat cushion thickness, as this affects the final measurement.

Remember, the perfect armrest height balances aesthetics and functionality, enhancing both the sofa's visual appeal and your outdoor relaxation experience.
