Keep both floors part of your everyday life.
Explore a compact straight-stairlift option for the home you love. Start with your staircase, the way you move and the details that make a good fit.
- 300 lb
- Listed weight capacity
- 11 inches
- Standard folded width from wall
Optional folding rail changes folded width. A home and user assessment confirms suitability.
Designed around real life
The right lift starts with the right fit.
Look beyond the model name. Think about the space, the person and the support you will want after installation.
Fold it out of the way
Review the folded lift and remaining passage space for everyone who uses the stairs.
Think through each transfer
Try the seat, swivel and controls together—not just the ride between floors.
Plan the whole installation
Doorways, rail endings, charging and handover belong in the proposal from the start.
Your questions, answered.
Choose a question to explore the details.
The SL300 is an indoor straight-stairlift option. An assessment needs to consider the entire flight, both landings, doorways and the person using it. A turn or intermediate landing may require a different rail solution.
Harmar lists 11 inches from the wall in the standard configuration, or 13⅝ inches with the optional folding rail. Neither number establishes the remaining walking space in your home. Measure the full installation and the passage alongside it.
The listed seat is 16½ inches wide by 15 inches deep. The manufacturer lists an 85-degree manual swivel with an interlock. Ask to try the proposed seat, controls and getting on and off with appropriate assistance; capacity alone does not establish fit.
Battery operation allows use during an outage, but the number of journeys depends on battery condition and use. Ask where the chair must park to charge, how to recognize a charging problem and what to do if power remains off. Do not rely on a maximum trip claim as a guaranteed reserve.
An automatic folding rail is an available option, not standard equipment. Ask the installer to show where the rail ends in both positions and how it affects nearby doors and walking routes.
Request a written scope covering the rail layout, site preparation, electrical requirements, installation, handover and service contact. Ask for an itemized price and written warranty responsibilities; this page does not promise a price or installation date.

Selected facts checked September 22, 2026 against Harmar’s SL300 specifications and document links. Buyer questions are editorial guidance; confirm current configuration and operating instructions.
The person. The staircase. The everyday routine.
Make room for
the right questions.
A specification helps narrow the conversation. The next step is understanding the complete installation and how you will use it.
The space around the lift
Review the stairs, both landings, nearby doors and space for other household members. Folded width alone cannot confirm the fit.
Getting on, riding and getting off
Discuss the seat, controls and transfers with the person who will use the lift. Ask to see the exact configuration being proposed.
Ownership after installation
Ask about operating instruction, battery care, maintenance, warranty terms and a clear service contact.

Two options. Your home. Your fit.
SL300 or SL600?
Both serve indoor straight stairs. Here’s where they differ—and what to try before you choose.
Pinnacle SL300
A compact seat. A straightforward starting point.
- Weight capacity
- 300 lb
- Seat width × depth
- 16½ × 15 inches
- Standard folded width¹
- 11 inches
- Retractable seat belt
- Optional
- Chassis obstruction sensor
- Optional
Pinnacle SL600
A wider seat, with more features included.
- Weight capacity
- 350 lb
- Seat width × depth
- 18 × 14⅜ inches
- Standard folded width¹
- 10½ inches
- Retractable seat belt
- Standard
- Chassis obstruction sensor
- Standard
Start with the person, not the model number.
Try the seat, controls and swivel. A wider seat or higher capacity does not automatically mean a better fit.
Then check the space around it.
¹ Widths are measured from the wall with the standard lift folded. A half-inch difference does not establish usable walking clearance. Optional folding rails change the dimensions; confirm the exact configuration.
Not sure which fits?
Bring both options into your home assessment.
Clarity before commitment
Ask for the complete picture.
A written proposal should explain the equipment, preparation, installation and support—not just the chair.
- The selected model, options and rail layout
- Site preparation and what installation includes
- Equipment demonstration and operating documents
- Warranty, service responsibilities and total quoted scope
