Sit-to-Stand Lift vs Hoyer Lift: When to Switch and When to Keep Both

When should you switch from a sit-to-stand lift to a Hoyer lift? Switch when the person can no longer take some weight through their legs, sit up unaided, grip the handles or follow simple instructions. Knees that buckle partway up are the clearest sign. Ask their therapist to reassess first.

Sit-to-stand lift vs Hoyer lift: why the right answer changes

A sit-to-stand lift only works while the person can do part of the work. A Hoyer lift holds the whole body in a sling, so the person doesn't have to stand at all.

A sit-to-stand needs their legs, their balance and their grip to hold up through the whole lift. As leg strength fades, which it often does, that becomes less certain. If their legs give out halfway up, a sit-to-stand won't hold them the way a full-body sling would. A lift that was fine for Dad in the spring might not be safe for him by fall.

At Selected Comfort, we help families choose between both types every day, and you can compare them side by side on our patient lifts page. If you haven't bought a lift yet, our sit-to-stand vs full-body patient lift comparison is the better place to start.

6 signs it's time to switch to a Hoyer lift

You only need to see one of these before you book a reassessment. They aren't a diagnosis, and the therapist makes the call.

1. Their knees buckle or give way during the lift, even occasionally.
2. They slide, slump or lean to one side when sitting on the edge of the bed.
3. They let go of the handles, or can't keep hold for the whole lift.
4. They don't lean forward when you ask, or they get frightened or agitated in the lift.
5. The caregiver is taking more of the weight each time, or the transfer now needs two people.
6. They need lifting from lying down or from the floor. A sit-to-stand can't do either.

Good days and bad days

Strength usually goes up and down rather than dropping steadily. A poor night's sleep, an infection or a new medication can turn an easy transfer into a risky one. Whatever lift you use has to be safe on their worst day.

What to do when you notice the signs

Stop, get a reassessment, then prepare the room and the sling before the new lift arrives.

1. Stop the transfer that worried you. If their knees buckled, speak to their therapist or doctor before you try it again.
2. Ask for a reassessment. A PT or OT can watch a transfer and tell you whether the person still meets the sit-to-stand lift weight-bearing requirements.
3. Check the care team's plan. It may say how many caregivers each transfer needs.
4. Measure the bedroom. A full-body lift needs a gap under the bed for its base and room to turn toward the chair and the door.
5. Order the right sling. A full-body lift takes a different sling, sized to the person.
6. Practise before you depend on it. Read the manual and the FDA's patient lift safety guidance, and ask the care team about training.

Which Hoyer lift should you move to?

For most families, start with a home electric lift like the Bestcare PL400EF. You raise and lower it with a button, so both your hands stay on the sling.

The hydraulic Bestcare PL400H is cheaper. It's fine for the occasional transfer if the caregiver is fit, but pumping the handle several times a day is hard work.

Choose a lift rated at least 50 lb above the person's weight, then check the sling's rating as well. Whichever is lower is your real limit.

If standard lifts don't go high enough, see our bariatric patient lifts. Every full-body model is on our Hoyer lifts page, and the Hoyer lift cost guide covers slings, batteries and the other extras.

Compare the lifts in this guide

All five lifts below are rated to 400 lb. The big difference is whether the person needs to bear weight.

Should you keep the sit-to-stand lift?

If it still works for some transfers, keep it. On the days the person can bear weight, a sit-to-stand makes toilet trips quicker and easier, and the Hoyer takes over for getting out of bed and for any day their legs can't be trusted.

Ask the therapist which lift goes with which transfer, then write it down so every caregiver does it the same way.

Bathrooms are where the sit-to-stand earns its place. In a small one it's usually easier to steer, as long as the base fits around the toilet. A full-body lift can be awkward to get into position there.

If you haven't bought a lift yet

Ask the therapist how the person's mobility is likely to change over the next year. If a full-body lift looks likely, factor that into what you buy now.

If a sit-to-stand suits them for the moment, I usually point home buyers to the Bestcare SA400H/SA400HE. Other models are on our sit-to-stand lifts page, and our patient lift buying guide goes into more detail.

Mistakes to avoid when switching

The biggest mistake is waiting for a fall before acting. If their knees buckle even once, call the therapist.

• Don't reuse the standing sling. It won't fit a full-body lift.
• Check the gap under the bed. If the base can't slide under, the lift can't reach the person.
• Leave at least 50 lb of capacity headroom, and check the sling's rating too.
• Tell every caregiver when you switch, so nobody uses the old lift for a transfer it's no longer safe for.

The bottom line

Keep using a sit-to-stand only while the person can reliably bear weight, sit up and hold on, judged on their weakest day. Once the knees start to buckle, get a reassessment and plan the move to a full-body lift.

For most homes that means an electric Hoyer like the Bestcare PL400EF, with the sit-to-stand kept for bathroom trips on stronger days. You can see both types on our patient lifts page.
