The Raizer II from Liftup A/S is a battery‑powered mobile lifting chair engineered to assist a person who has fallen to get into a seated or nearly standing position. According to manufacturer material, it is designed for single‑assistant operation and requires no heavy manual lifting.
Key specifications
The Raizer II supports a maximum user weight of 150 kg (≈ 330 lbs). On a full charge, it can perform approximately 40 lifts at full load; under lighter load conditions the number may rise, with some literature citing up to about 80 lifts. Charging time is up to ~6 hours for a full charge, while a brief 10–15‑minute charge may permit a single lift. The device consists of a seat unit and removable legs and back‑rests; one specification lists the total weight at about 13 kg (8.5 kg seat + 4.5 kg legs/back supports) in one regional version.
Use & assembly
The device is designed for rapid deployment around a fallen person. The assistant places the seat by the person, fits the back‑rest panels and leg assemblies (typically colour‑coded or marked for correct side), then fastens the seatbelt and uses a side‑panel or remote control to raise the user. The lift time is typically around 20‑30 seconds once in operation. The user manual emphasises that the chair is not intended for transporting a person, only for lifting them into a safe seated or near‑standing position.
Practical considerations
Because the Raizer II uses a battery, it is important to keep it charged and in suitable environment: performance may degrade in very low temperatures. While it is designed for a one‑assistant workflow, space around the fallen person must permit the legs and back‑rests to deploy safely. Overloading beyond 150 kg triggers a built‑in cut‑out/alarm system. Regular inspection and maintenance are advised to ensure safe operation, especially in professional or institutional settings.
Applications
The chair is appropriate for home care settings, assisted living facilities, nursing homes and emergency response contexts where fall recovery is needed. Its portability (disassembly into bags) adds flexibility for various environments.
In summary, the Raizer II offers a structured solution for lifting fallen individuals with reduced physical exertion by caregivers. While it carries a significant cost compared to simpler aids—with U.S. distributor pricing around $5,445—the features such as a battery-powered lift, single-assistant operation, and clear assembly indicators make it a practical tool for settings where falls present a frequent risk.
