- 8 inch wheels for the elderly rollator provide strong ground grip with an anti-skid tread pattern to prevent slipping on most terrains. - Safety first with a dual-brake system: control speed easily with the brake handle, and press the brake handle to lock the brakes when you want to sit on the seat. The wheel tread also adds resistance to reduce slipping between wheel and surface. - Lightweight yet sturdy: aluminum construction supports up to 136 kg. The thick breathable seat and padded backrest offer a comfortable, secure rest when taking a break during walks. - 6 level height adjustments: thumb-press button design allows you to set the height from 31.5" to 35.5" (handle from ground) for a proper, comfortable fit. Use scenarios: - Indoors and on paved surfaces: suitable for daily errands and trips to stores, with stable stopping and resting options. - Outdoor walks on sidewalks or light uneven terrain: larger wheels and grip help maintain stability on varied surfaces. - Sit-and-rest breaks: easily lock the brakes and sit on the seat; height can be adjusted to suit different users for comfortable use.
