Every stairlift quote says the equipment is safe. Here is what that should actually mean, so you can check rather than take somebody’s word.
1. Obstruction sensors
Sensors on the footrest and the chassis that stop the lift if something is in the way. A shoe left on a step, a cat, a grandchild’s toy.
The thing to check is not whether they exist but whether they are tested at each service. A sensor nobody has tested in three years is a sensor you are assuming works.
2. A seat belt, and using it
Standard on serious equipment, retractable on most. The difficulty is never the belt, it is the habit. People skip it on a short flight, and a short flight is enough.
If you are buying for somebody else, ask for the belt to be demonstrated at handover and treat it as part of the training rather than an afterthought.
3. Battery operation and a manual lowering method
These lifts run on batteries that charge at parking points, which is why they work in a power cut. Harmar states the Pinnacle SL600HD manages up to 60 trips on batteries during an outage.
Separately, there should be a manual lowering method for the case where the batteries are flat as well. Ask to be shown it at handover, and ask again at the first service, because it is the one thing nobody remembers.
4. A swivel seat that locks
At the top landing the seat turns to face away from the stairs, so somebody stands up onto a landing rather than sideways above a drop. It should lock in position rather than being free to rotate.
On a tight landing, a powered swivel is worth more than it costs and is the option most often left off a quote by whoever is trying to be cheapest.
5. Overspeed braking
A mechanical brake that engages if the carriage ever travels faster than it should, independent of the drive and the electronics. It is the feature you will never see work, and the one you would want if anything else failed.
6. Controls somebody can actually use
A constant-pressure control, so the lift only moves while the control is held, is a safety feature rather than an inconvenience. Two remotes so the lift can be called from either end. Controls operable by somebody with arthritis or limited grip.
Test this with the actual person rather than assuming. A control that requires a firm pinch is a control that will be a struggle twice a day.
What is not a safety feature
Upholstery color, a folding rail, a key lock. All useful, none of them safety. Key locks prevent unauthorized use, which matters in a house with young grandchildren, and that is a different thing from the list above.
The safety question nobody asks
Who services it, and how often. Every feature above degrades without maintenance, and the annual service is where sensors are tested rather than looked at. Our service page covers what that involves, including on equipment we did not install.
And the transfer itself
The riskiest moment with any stairlift is getting on and off it. Bruno does not recommend the Elan for somebody who scoot-pivot transfers without bearing weight through their legs, or whose knees buckle during a stand-to-sit transfer, and names the Elite for those situations.
That is manufacturer guidance rather than a sales preference, and it is worth more than any feature list. Say what the transfer looks like before anybody orders. Grab bars and transfer equipment ship free from our online shop.
Features for a household rather than a person
A key lock matters in a house with young grandchildren, because it prevents the lift being operated as a fairground ride. A folding rail reduces a trip hazard at the foot of the stairs for everybody else in the house.
Neither protects the rider. Both protect the household, and they are worth asking about separately rather than letting them stand in for the list above.
What to check at the annual service
Ask for these specifically, because “serviced” covers a wide range:
- Obstruction sensors tested, not just inspected.
- Batteries load-tested rather than voltage-checked.
- Seat belt webbing and buckle checked.
- Travel limits verified at both ends.
- Fixings torqued, since thermal movement loosens them.
- The manual lowering method demonstrated again.
The CDC reports falls as the leading cause of injury death among adults 65 and over, which is the reason to treat a service visit as a safety check rather than a formality.
Safety for the installer too
Worth a line, because it tells you about a company. A crew that protects the route from the door, tests under load before leaving, and demonstrates the manual lowering method is a crew working to a process. One that does not is working from memory.
Ask who is coming: their own technicians or a subcontractor. That matters most on the second visit, when somebody who saw the job the first time recognizes what has changed. Our service page covers what happens afterward.
