Protekt® STS Compact 500 Electric Sit To Stand Lift 34500-COM by Proactive

The Sit-to-Stand Lift That Actually Fits in Your Bathroom

One of the most common frustrations caregivers run into with sit-to-stand lifts is space — a lift that works beautifully in a showroom can be impossible to maneuver through a narrow bathroom doorway or position around a toilet.

The Protekt® STS Compact 500 (Model 34500-COM) by Proactive Medical was designed with that problem in mind. Its compact base opens to just 45” turning diameter and closes to 41.9” — narrow enough to navigate standard home doorways and maneuver around toilets, commodes, and chairs in real home spaces.

At 500 lbs capacity with full electronic controls, it’s a capable, safe, and genuinely compact sit-to-stand lift, and part of our full selection of electric sit-to-stand lifts.

Why We Like This Lift

We like the STS Compact 500 because it takes the most common complaint about sit-to-stand lifts — that they’re too big to use where transfers actually happen — and makes it a non-issue. The 41.9” closed turning diameter means it goes where other lifts can’t. The 4.9” base height means it slides under furniture without repositioning the patient. The removable footplate and adjustable knee pad mean it adapts to the patient rather than the other way around. And the IP54 splash protection means you can use it confidently in a bathroom environment without worrying about moisture and the electronics. For families dealing with a loved one who has some leg strength but can’t stand alone, this is a lift that fits both the physical need and the physical space.

Is This the Right Type of Lift?

A sit-to-stand lift like the STS Compact 500 is designed for patients who still have some ability to bear weight on their legs — even if that strength is limited. The lift brings them from sitting to a semi-standing position, supported by the sling and the knee pad, while their feet remain on the footplate and their legs do a small amount of work.

If your loved one cannot bear any weight on their legs at all — if their legs provide no support during a transfer — a full-body sling lift is the right choice instead. Full-body lifts fully suspend the patient with no weight-bearing required. You can browse our electric patient lift lineup if that sounds like a better fit, or call us at 1-800-956-6616 and we’ll help you figure out which type is right for your situation.

Feature Highlights

Compact Base — Designed for Real Home Spaces

The STS Compact 500 has a closed turning diameter of 41.9” and a base height of just 4.9”. In practice, this means it fits through standard home doorways, maneuvers around a toilet without repositioning, and slides under most beds, chairs, and furniture for easy patient positioning. As Proactive Medical’s own presenter puts it: “You can see by the size it is a very compact device. Makes it easy to fit through bathrooms, doorways, around toilets.” For caregivers who’ve struggled to maneuver a larger lift in a small bathroom, this is the difference that matters.

Removable Footplate — Adapts to the Patient and the Goal

The footplate gives the patient a stable surface for their feet during a standard transfer. For patients working on rehabilitation — building leg strength toward independent standing — the footplate can be removed entirely so the patient stands with feet flat on the ground. That one feature makes this lift useful across a range of recovery stages, not just one fixed point in a patient’s care.

Adjustable Cushioned Knee Pad — Comfort and Support During Every Transfer

The knee pad adjusts in and out to accommodate different patient builds, and provides cushioned support for the knees throughout the transfer. For sling-assisted toilet transfers, the knee pad can be removed entirely to allow full toilet access. The adjustability means the lift works for a range of patient sizes without additional accessories.

Electronic Controls With Backup — Never Stranded Mid-Transfer

The hand pendant raises and lowers the lift with simple up and down buttons. If the pendant fails, a second set of auxiliary buttons on the back of the control unit does the same job — so a broken remote never leaves a patient suspended mid-transfer. An emergency stop button on top of the unit disables the lift immediately if needed. And in a complete power failure, a manual emergency lowering knob allows the caregiver to safely lower the patient without electricity. These redundancies matter in a home environment where a technician isn’t on call.

IP54 Rated — Splash-Resistant for Bathroom Use

The STS Compact 500 carries an IP54 ingress protection rating, meaning it’s protected against dust and water splash from any direction. For a lift that will regularly be used near toilets, commodes, and sinks, this protection rating means the electronics are built for the environment they’ll actually operate in. Most patient lift spec sheets don’t mention IP ratings at all — this one does, because it was designed for bathroom use.

Locking Lever Base — Stays Where You Put It

The base opens and closes with a manual lever that locks in both the open and closed positions — confirmed in the product video. When you open the base for a transfer, it locks open. When you close it to move the lift, it locks closed. There’s no risk of the base shifting mid-transfer because it wasn’t fully locked. It’s a simple mechanism that adds meaningful safety in a one-caregiver situation.

Your Options at Checkout

Sling (Choose One, or Order the Lift Only)

The right sling depends on how much weight your patient can bear on their legs. If you’re not sure, call us at 1-800-956-6616 before ordering — choosing the wrong sling type is one of the most common mistakes with sit-to-stand lifts and we’d rather help you get it right first.

No Sling

Choose this if you already own a compatible Proactive Medical sit-to-stand sling in the correct size and type for your patient.

Sit-to-Stand Sling

The standard sling for patients with at least 60% weight-bearing capacity. Tucked behind the patient at mid-back with a waist strap secured around the front, it connects to the lift’s hook and raises the patient to a semi-standing position. As shown in the product video, the patient leans back into the sling with knees braced against the knee pad — they are not standing fully upright. If the sling rides up under the patient’s arms during lifting, stop immediately and reassess the fit.

Transfer Sling

Designed for patients with minimal weight-bearing capacity — less than 60%. Lifts the patient to a semi-standing position with more support than the standard sit-to-stand sling. A good option when the patient has very limited but not zero leg strength.

Padded Sit-to-Stand Sling

The same function as the standard sit-to-stand sling, with added padding for patients who need more comfort during transfers. Suitable for patients with at least 60% weight-bearing capacity. A good choice when transfers happen multiple times daily and patient comfort is a priority.

Slings are available in multiple sizes. If you’re unsure which sling type or size is right, call or chat with us before ordering.

Battery and Charger Kit (Optional)

Includes one Protekt battery pack and one external battery charger cradle with power cord. Charge one battery while using the other — no downtime between transfers. The lift delivers 25 full cycles per charge, but for high-use situations a spare battery ensures the lift is always ready.

BATTERY NOTE: The battery and cradle can be purchased separately in the “Frequently bought with” section under the product photos above. Or select the kit, which includes both, in the product options when you’re adding to the cart.

Setup and Safety Notes

The STS Compact 500 ships in one box and assembles without special tools using the easy tools included. Read the owner’s manual completely before the first transfer — particularly the sling setup instructions and the weight-bearing assessment guidance.

Medicare, Insurance, and HSA/FSA

Medicare covers manual hydraulic patient lifts as durable medical equipment, but not electric lifts. If you’re set on an electric lift, there’s a path worth knowing about: Medicare may reimburse you for what it would have paid toward a comparable manual lift, and you pay the difference. The catch is that any Medicare benefit requires the purchase to go through a Medicare-enrolled DMEPOS supplier — which ADHME is not. If maximizing your Medicare benefit is the priority, we’d recommend going that route instead.

Private insurance: Many private insurers cover electric patient lifts when prescribed as medically necessary by a physician. ADHME doesn’t bill insurance directly, but provides a detailed paid invoice with the HCPCS code that you can submit to your private insurer for reimbursement. Contact your insurer before ordering to confirm your coverage and any required documentation.

HSA and FSA: Patient lifts are generally eligible expenses under Health Savings Accounts and Flexible Spending Accounts. The paid invoice ADHME provides serves as your documentation for reimbursement.

Frequently Asked Questions

How is a sit-to-stand lift different from a full-body patient lift?

A full-body patient lift fully suspends the patient in a sling — no weight-bearing required. It’s used when the patient cannot support any of their own weight. A sit-to-stand lift like the STS Compact 500 is for patients who still have some leg strength. The lift brings them to a semi-standing position while their feet remain on the footplate and their legs do a small amount of work. If you’re not sure which type is right for your situation, call us at 1-800-956-6616 — it’s the most important question to get right before purchasing.

Which sling should I choose?

The right sling depends on how much weight your patient can bear on their legs. The sit-to-stand sling and padded sit-to-stand sling are for patients with at least 60% weight-bearing capacity. The transfer sling is for patients with less than 60% weight-bearing capacity who still have some leg function. If you’re not sure, call or chat with us before ordering — selecting the wrong sling type is one of the most common mistakes with sit-to-stand lifts.

Will this fit through a standard bathroom doorway?

Yes — the STS Compact 500 has a closed turning diameter of 41.9”, which fits through most standard interior doorways (typically 32”–36” wide). The 4.9” base height also allows it to slide under most chairs and furniture for easy positioning. As Proactive Medical demonstrates in the product video above, it’s specifically designed to maneuver through bathrooms, doorways, and around toilets.

Is this a Hoyer lift?

Hoyer is a brand name that has become a common term for any electric patient lift — similar to how Kleenex is used for tissue. The STS Compact 500 is a Proactive Medical electric sit-to-stand lift. It’s a different type of lift from a standard full-body Hoyer lift: it’s designed specifically for patients with some weight-bearing ability who need assistance standing, rather than for fully suspending a patient who cannot bear weight. If you’re looking for a full-body suspension lift, see our electric patient lift lineup.

Will insurance cover this lift?

Sit-to-stand lifts may be eligible for reimbursement through Medicare or private insurance when prescribed as medically necessary by a physician. Coverage and applicable codes vary by insurer — contact your insurer before ordering and ask specifically about coverage for powered sit-to-stand patient lifts.

If Medicare reimbursement is important to your decision, keep in mind that any Medicare benefit requires the purchase to go through a Medicare-enrolled DMEPOS supplier — which ADHME is not. If maximizing your Medicare benefit is the priority, we’d recommend going that route instead.

ADHME doesn’t bill insurance directly, but provides a detailed paid invoice that you can submit to your private insurer for reimbursement.

HSA and FSA: Sit-to-stand lifts are generally eligible expenses under Health Savings Accounts and Flexible Spending Accounts. The paid invoice ADHME provides serves as your documentation for reimbursement.
