What is the highest weight capacity stairlift available?

The Harmar Pinnacle SL600HD handles 600 lb, making it the highest-capacity residential stairlift on the US market. The next closest is the Bruno Elite SRE-2010 at 400 lb. If your rider weighs over 375 lb fully dressed, the SL600HD is the only name-brand residential option. Installed pricing runs $5,000–$7,500.

How much does a Harmar stairlift cost in 2026?

The Pinnacle SL600 standard indoor runs $3,500–$5,200 installed. The SL600HD bariatric (600 lb) runs $5,000–$7,500. The Summit SL350OD outdoor runs $4,000–$6,800. The RPL400 vertical platform lift runs $6,500–$12,000. The SL600HD has no price comparison because no competing product exists at that capacity.

Does Harmar make a curved stairlift?

No. Harmar makes only straight-rail stairlifts and platform lifts. If your staircase has turns, landings, or non-straight geometry, you need a curved stairlift from Bruno (CRE-2110), Handicare (Freecurve), or Stannah (Siena 260/Starla 260). Alternatively, Harmar’s RPL400 vertical platform lift can sometimes serve as an alternative to a curved stairlift by lifting the rider vertically between floors, but this only works for specific floor plans.

Is Harmar good for outdoor stairlifts?

Harmar makes the best outdoor stairlift for coastal and hurricane markets. The Summit SL350OD features a top-mounted motor and electrical housing (keeps electronics above flood level), marine-grade materials rated for salt air and UV, and extruded aluminum rail with marine-grade coating. We have installed SL350OD units that operated through four named hurricanes without component failure. For covered porches with minimal weather exposure, Bruno’s outdoor unit is also a strong option. For fully exposed exterior stairs in coastal areas, Harmar is the recommendation.

What warranty does Harmar offer?

Harmar offers a 10-year motor/drivetrain warranty, a 3-year warranty on all other parts (the longest in the industry), a 1-year labor warranty (the most generous among major brands), and a 1-year battery warranty. The 3-year parts warranty gives you 12–15 months more coverage than Bruno (2 years), Handicare (2 years), or Stannah (27 months) on components like control boards, safety sensors, and seat mechanisms.

Where is Harmar manufactured?

Harmar is headquartered in Sarasota, Florida, with manufacturing and parts warehouse operations at that location. The Florida base means parts supply continues through hurricane events — after Hurricane Ian in 2022, Harmar resumed shipping within 72 hours of the storm clearing. Harmar sells through authorized dealers across the US.

How does Harmar compare to Bruno?

Harmar wins on bariatric capacity (600 lb vs. 400 lb), outdoor weather engineering, parts warranty length (3 years vs. 2 years), labor warranty (1 year vs. 30 days), battery backup (60 cycles vs. 20+), and folded width (10.5 inches vs. 14.25 for Bruno Elite). Bruno wins on curved-rail availability (Harmar has none), dealer network size, indoor ride quality, brand recognition, and the beltless direct-drive motor. For standard indoor straight-rail installs under 400 lb, Bruno is usually the better choice. For heavy-duty, outdoor, or hurricane-market applications, Harmar is superior.

Can a Harmar stairlift handle a power outage?

Yes. The Pinnacle SL600 and SL600HD are rated for up to 60 up-and-down cycles on battery backup during a power outage. That is approximately 3x more than Bruno’s 20+ cycles and 5–6x more than Handicare’s 8–12 cycles. For homes in hurricane, blizzard, or rolling-blackout markets where power can be out for days, Harmar’s battery backup is the highest in the industry.

What is the Harmar RPL400 platform lift?

The RPL400 Highlander is a residential vertical platform lift that raises a wheelchair, scooter, or standing rider straight up to 53 inches. It carries 600 lb, includes a non-skid platform with automatic folding access ramp, and works both indoors and outdoors. It is not a stairlift — it lifts vertically rather than along a rail. It is the right product for raised entries, short-rise deck access, or situations where the rider cannot transfer from a wheelchair. Installed pricing runs $6,500–$12,000.

Is Harmar available in my state?

Harmar has authorized dealers across the United States, with the strongest coverage in the Southeast, Gulf Coast, Sun Belt, and Midwest. Dealer density is thinner in the Northeast and Pacific Northwest compared to Bruno. If you are outside Harmar’s strongest dealer markets, a Harmar install is still available but may require a dealer from a neighboring region, which can affect install scheduling.

Harmar Stairlift Review (2026): Heavy-Duty & Outdoor Specialist

Harmar Stairlift Review (2026): Heavy-Duty & Outdoor Specialist

Harmar is not the brand most people have heard of. What they have is the only true 600 lb bariatric stairlift on the US residential market, the best-proven outdoor unit in hurricane conditions, and a factory in Sarasota, Florida, that shipped parts through four named storms without missing a delivery window.

Company background

Harmar is headquartered in Sarasota, Florida. They manufacture stairlifts, vertical platform lifts, and vehicle lifts. The Sarasota location is not incidental — Florida is the largest residential stairlift market in the US. Harmar designs and tests for the conditions 20 miles from the factory: salt air, 95°F heat with 90% humidity, hurricane-force winds, and storm-surge flooding.

Harmar sells through authorized dealers. Smaller network than Bruno, but well-distributed in the Southeast, Gulf Coast, and Sun Belt.

The 2026 model lineup

Pinnacle SL600: premium straight rail

Capacity	350 lb
Speed	20 ft/min
Folded width	10.5″ (narrowest premium)
Battery backup	Up to 60 cycles
Drive	Nylon polymer worm drive (self-locking)
Max rail	Up to 70 feet
Installed price	$3,500–$5,200

Two standouts: 10.5″ folded width is the narrowest in the premium category. 60-cycle battery backup is 3x Bruno’s 20+ cycles — runs for days during power outages.

Pinnacle SL600HD: the 600 lb bariatric king

Capacity	600 lb
Seat width	22″ (widest residential)
Drive	Reinforced worm drive, uprated motor
Rail	Reinforced with heavy-duty mounting hardware
Installed price	$5,000–$7,500 (40–50% above standard)

The only residential stairlift on the US market above 400 lb. Next closest: Bruno Elite at 400 lb. For riders over 375 lb fully dressed, this is the only option. We install 15–20 SL600HD units per year, primarily Southeast and Midwest.

May require structural reinforcement of stair treads for the higher load. A qualified installer will assess before confirming.

Summit SL350OD: the outdoor workhorse

Capacity	350 lb
Temp rating	0°F to 125°F
Rail	Extruded aluminum, marine-grade coating
Seat	Marine-grade vinyl with weatherproof cover
Motor	Top-mounted (above flood line)
Installed price	$4,000–$6,800

Designed from the ground up as an outdoor product, not adapted from indoor. The top-mounted motor keeps electronics above the waterline during flooding — Florida engineering for Florida problems.

RPL400 Highlander: vertical platform lift

Capacity	600 lb (wheelchair + rider)
Max lift height	53 inches
Platform	Non-skid with auto-folding ramp
Indoor/Outdoor	Both (weather-resistant)
Installed price	$6,500–$12,000

Not a stairlift. A vertical lift for wheelchair users at raised entries. The right product when the rider cannot transfer from wheelchair to seat.

Harmar does not make a curved stairlift. For curved staircases: Bruno CRE-2110, Handicare Freecurve, or Stannah Siena 260. Alternatively, the RPL400 can serve as an alternative by lifting vertically between floors.

The hurricane market advantage

Field-proven through four named storms. Every unit continued operating post-storm with no component replacement beyond battery check. The top-mounted motor keeps electronics above flood line.

Salt air: Aluminum rail with marine-grade coating outlasts powder-coated steel
Moisture: Top-mounted motor + sealed connectors prevent intrusion
UV: Marine-grade vinyl rated for Florida sun exposure (highest UV in continental US)
Storms: Stair-mounted design (not wall-mounted) survives wind events

After Hurricane Ian (2022), Harmar resumed shipping within 72 hours. Most competitors took 2–3 weeks.

Warranty breakdown

Motor/drivetrain: 10 years (explicit, not vague “lifetime”)

All other parts: 3 years (industry longest)

Labor: 1 year (most generous)

Batteries: 1 year (matches Stannah, exceeds Bruno/Handicare)

Harmar’s 3-year parts warranty gives you 12–15 months more than Bruno (2 years), Handicare (2 years), or Stannah (27 months). The 1-year labor warranty is also the most generous — Bruno covers 30 days.
