LESS EFFORT SITTING DOWN & STANDING UP: Adds 5 cm (2 inch) to the toilet height to reduce knee and hip flexion when sitting and standing. The soft-close lid lowers gently and quietly, helping to prevent slamming and sudden noise CHECK COMPATIBILITY BEFORE BUYING: Measure the distance between the two toilet fixing holes (centre to centre): it must be 7.5–17.5 cm (3–7 in). The riser measures 43 × 37 cm (16.5 × 14.5 in) and the inner opening is 22 × 28 cm (8.6 × 11 in), designed for standard oval toilets. If your toilet dimensions differ, it may not fit correctly STABLE INSTALLATION IN MINUTES: Secures into the toilet’s original fixing holes using rubber plugs and screws—no adhesives or special tools required. Includes all fittings and an Allen key; you’ll only need a screwdriver (not included) to finish installation and secure it firmly DURABLE & EASY TO CLEAN: Made from duroplast, a hard, stable material for daily use, pleasant to the touch and wear-resistant. Clean with water and mild soap; avoid bleach, chlorine, alcohol and abrasive products to protect the surface SAFE FOR EVERYDAY USE: Not intended for prolonged sitting, nor for use as a bench or step. Do not place weight on one side or make sudden movements when sitting. Check screw tightness regularly, always use on a dry, stable surface, and respect the maximum user weight of 113 kg (250 lb), Weight: 7.71617917 pounds, Manufacturer: IMD SL
