The AY04 Straight Electric Stair Chair is a heavy-duty mobility solution designed to help trained caregivers move individuals with limited mobility along compatible straight stairways. Its electric assistance reduces the physical effort associated with manual stair transport, making it suitable for homes, healthcare environments, public facilities, and emergency-preparedness applications.
Built from durable aluminum alloy, the AY04 supports users weighing up to 485 pounds. The chair itself weighs approximately 81.7 pounds, providing substantial strength while retaining a foldable design for more convenient storage and transportation.
An integrated night-lighting system improves visibility in dim hallways, stairwells, and other low-light environments. This added illumination helps the operator see the route more clearly when natural or overhead lighting is limited.
A four-point positioning belt helps stabilize the passenger’s upper and lower body throughout the transfer. Widened armrests feature a contoured groove design, providing a comfortable place for the user to position their arms while seated.
When not in use, the chair folds to reduce its storage footprint. This makes it easier to keep near a staircase, place inside an appropriate vehicle, or store with other mobility and emergency equipment.
Ideal Applications
✔ Homes with straight staircases
✔ Healthcare and rehabilitation facilities
✔ Assisted living communities
✔ Public buildings and offices
✔ Emergency-preparedness planning
✔ Individuals with limited stair mobility
✔ Caregiver-assisted stair transfers
✔ Compatible vehicle storage

FAQs
What is the AY04 Straight Electric Stair Chair?
The AY04 is an electrically assisted stair chair designed to help trained caregivers move a seated person along a compatible straight staircase.
Who may benefit from using the AY04?
It may benefit seniors, individuals with limited mobility, and people who cannot safely walk up or down stairs without assistance.
What is the maximum weight capacity?
The AY04 supports users weighing up to 485 pounds.
How much does the stair chair weigh?
The chair has a net weight of approximately 81.7 pounds.
What is the frame made from?
The AY04 is constructed from durable aluminum alloy.
Is the AY04 manually operated?
It uses electric assistance to reduce the physical effort required from the operator. Caregiver guidance and control are still required throughout the transfer.
Can the user operate the stair chair independently?
No. The AY04 is intended for operation by a trained, physically capable caregiver or attendant.
Can it travel both up and down stairs?
The supplied information does not specify its approved travel directions. Confirm whether powered ascent, descent, or both are supported before use.
Can the AY04 be used on curved stairs?
No. It is designed for compatible straight stairways and should not be used on curved or spiral staircases.
Will it work on every straight staircase?
No. Compatibility depends on stair width, step dimensions, slope, landing space, surface condition, and available maneuvering room.
What staircase measurements should be checked?
Measure the stair width, tread depth, riser height, incline, top and bottom landing space, and any turns or obstructions. Compare these measurements with the manufacturer’s requirements.
Can it be used on outdoor stairs?
Do not use it outdoors unless the manufacturer specifically permits that application. Wet, icy, damaged, or uneven steps can compromise control.
How many caregivers are required?
The required number of operators is not specified. Follow the manufacturer’s instructions, facility policy, and user care plan rather than assuming one-person operation is appropriate.
Does the AY04 include a seat belt?
Yes. It features a four-point positioning belt.
What does the four-point belt do?
It helps stabilize the user’s upper and lower body and maintain proper seated positioning during stair movement.
Is the belt a vehicle restraint?
No. The four-point belt is intended for positioning on the stair chair and is not an approved motor-vehicle occupant restraint.
Does the chair include lighting?
Yes. Integrated night lighting helps improve visibility in dim hallways and stairwells.
Should the night light replace normal stairwell lighting?
No. Use adequate building lighting whenever possible. The integrated light should be considered supplemental visibility support.
What are the armrests like?
The AY04 has widened armrests with a contoured groove design for comfortable arm positioning.
Does the chair fold?
Yes. Its folding frame reduces the storage footprint when the chair is not in use.
What are the folded dimensions?
Folded dimensions are not included in the supplied specifications. Confirm them before purchase if storage or vehicle fit is important.
Will the folded chair fit in every vehicle?
Not necessarily. Compare the verified folded dimensions and 81.7-pound chair weight with the vehicle’s cargo opening and load capacity.
Can a user remain seated in the AY04 during vehicle travel?
No. Transfer the user into an approved vehicle seat and secure the unoccupied stair chair separately.
What type of battery does it use?
Battery type, capacity, charging time, and runtime are not provided in the supplied information. Verify these specifications before ordering.
What happens if the battery loses power on the stairs?
Follow the manufacturer’s emergency procedure. Operators should check the battery before every transfer and receive training on safely responding to a power interruption.
How fast does the AY04 travel?
Travel speed is not listed. The operator must use only the approved speed and control settings described in the product manual.
Is the AY04 an evacuation chair?
It may support emergency-preparedness planning, but its formal evacuation rating and applicable certifications are not specified. Confirm local requirements and manufacturer documentation before designating it for emergency evacuation.
Can it replace an elevator or permanent stair lift?
The AY04 is a caregiver-operated transfer device, not a permanently installed stair lift. The best solution depends on the user, building, and frequency of stair access.
Is training required?
Yes. Every operator should complete product-specific training and practice without an occupant before transporting a user.
What should be checked before each use?
Inspect the frame, folding joints, electric drive, controls, battery, positioning belt, armrests, and all stair-contact components. Confirm that the route is clear and dry.
Should the user be medically assessed before using it?
A healthcare or mobility professional should assess users with complex positioning needs, severe balance limitations, recent injuries, or medical conditions that could make stair transport unsafe.
What safety precautions should operators follow?
Never exceed the 485-pound capacity, use the four-point belt correctly, verify stair compatibility, and keep the user centered throughout movement. Do not operate on wet, curved, obstructed, or damaged stairs.
Is the AY04 a substitute for emergency medical services?
No. Contact emergency services when a person is injured, medically unstable, or cannot be moved safely with the available equipment and trained personnel.
