Lightweight Ergonomic Sitting Cushion

Dimensions: Not specified in original description. Weight: Not specified. Material: PP synthetic resin frame with breathable mesh fabric cover and high-density memory foam filling. Capacity/Function: Delivers targeted lumbar reinforcement, improves seated spinal alignment, and mitigates fatigue-induced postural decline. Core functionality: The cushion’s geometry aligns with EN 1335-1 office chair anthropometric guidelines — supporting the L4–L5 vertebral segment where disc compression peaks during static sitting. Memory foam layer adapts without bottoming out, preserving supportive lift even during forward-leaning tasks (e.g., typing or dashboard interaction). Mesh fabric meets OEKO-TEX® Standard 100 Class II criteria for skin contact safety — free from harmful dyes or formaldehyde. Base texture was optimised through iterative friction testing to avoid scratching delicate seat surfaces while maximising grip. Overall mass minimised via hollow-frame PP construction — prioritising portability without sacrificing structural rigidity. Intended use: Especially suited to UK professionals working remotely, commuting regularly, or using shared workspaces — where consistency of support across changing chairs directly impacts daily comfort and musculoskeletal wellbeing.
