SUPPORT FOR SITTING DOWN & STANDING UP: Raises the toilet by 7.5 cm (3 in) to reduce effort when sitting and standing. Ideal for older adults, rehabilitation or reduced mobility, helping to lessen strain on knees and hips. COMPATIBILITY IS ESSENTIAL (REAR ACCESS REQUIRED): Only suitable for toilets where you can access the back to tighten the nuts. Not compatible with concealed, wall-hung toilets or any toilet with no rear gap where you can’t reach behind by hand. MEASUREMENTS TO ENSURE A PROPER FIT: Fits toilets with fixing hole distance 13.5–17.5 cm (5.3–7 in) and distance from fixing holes to the front edge 44–46 cm (17–18 in). Overall size: 46 × 40.5 cm (18 × 16 in). Inner opening: 23 × 28.5 cm (9 × 11 in). If your toilet is outside these ranges, it will not be compatible. STABLE INSTALLATION IN MINUTES: Attaches to the original toilet fixing holes with the included long screws, nuts, washers and rubber supports. Installs in minutes on a dry, stable surface. You only need a screwdriver (not included). DURABLE MATERIAL & SAFE EVERYDAY USE: Made from robust duroplast, easy to clean with water and mild soap; avoid bleach, chlorine, alcohol and abrasive cleaners. Designed as a sit-to-stand aid, not as a step or bench; do not apply sideways loads. Check screw tightness regularly.
