Choosing a stair lift for a curved staircase starts with a fit question: neither option here is described as a curved-track model. Both listings identify a 15-foot track, and the AmeriGlide Rave 2 is explicitly made for straight staircases. That means I would treat these as possible matches only for a suitable straight run, not assume either can follow a bend or landing.

For a straight staircase, the Universal Stair Lift stands out for its fold-flat design, either-side installation, and battery backup rated for more than 20 trips during an outage. The AmeriGlide Rave 2 is the clearer choice for buyers who want a battery-powered, self-installable setup with swivel seating and call stations at both ends. The main tradeoffs are power arrangement, installation approach, and whether the stated track fits the actual stairway.

Key Takeaways
- Neither listing confirms a curved track; the Rave 2 is specifically described for straight stairs, so verify track compatibility before buying for a staircase with a turn or landing.
- The Universal model folds flat against the wall and can be installed on either side, which may help preserve stair access in a narrow hallway.
- The Universal includes a rechargeable backup rated for more than 20 up-and-down trips during a power outage, while the Rave 2 is described as battery-powered.
- The Rave 2 is the only option explicitly described as self-installable and includes wireless call stations at both the top and bottom.
- Both listings specify a 350 lb capacity and 15 ft of track, so fit, power needs, and installation support are stronger differentiators than capacity.

Universal Stair Lift with 350 lb Capacity and 15 ft Track
The Universal lift earns the lead position here because it combines either-side installation with a fold-flat profile, two details that can make a shared staircase easier to use. When the seat and lift fold toward the wall, the stairs may remain more accessible to other household members. Its 350 lb capacity matches the Rave 2, so the distinction is not load rating but how the installation may fit the room.
Its strongest practical differentiator is the rechargeable backup battery, rated for more than 20 trips up and down during a power outage. That gives the listing a concrete outage-use claim; the Rave 2 is battery-powered, but its description does not state a specific outage-trip count. The Universal still needs a nearby standard AC outlet, so buyers should check outlet placement and confirm what charging requires. The listing says no wiring is required, which may simplify setup, but it does not establish that every home installation is straightforward.
The main limitation for this roundup is its unspecified staircase type. A 15 ft track alone does not show that the rail can follow a curve, wrap a landing, or be custom-shaped. Compared with the Rave 2, the Universal offers more flexibility about which side of the stairs it can use, but the AmeriGlide is more explicit about its straight-run scope and self-installable setup. I would shortlist this model for a straight stairway where its track arrangement is confirmed, and skip it for a curved staircase unless the seller confirms a compatible curved rail and installation plan.
Pros:- Folds flat against the wall to keep more of the stairway available.
- Can be installed on either side of the stairs.
- Rechargeable backup is rated for more than 20 trips during a power outage.
- Uses a standard AC outlet and is described as requiring no wiring.
Cons:- The listing does not specify whether the track supports curved staircases.
- The 15 ft track may not match the length or layout of a particular staircase.
- A nearby AC outlet is required.
Best for: Households with a straight staircase that value a fold-flat seat, choice of installation side, and a stated battery backup for outages.
Not ideal for: Buyers who need a confirmed curved track, cannot place the lift near an AC outlet, or have a stairway that exceeds or does not match the 15 ft track.
- Capacity:350 lb
- Track length:15 ft
- Staircase placement:Can be installed on either side
- Power:Standard AC outlet; no wiring required
- Battery backup:Rechargeable; rated for 20+ up-and-down trips during a power outage
- Safety mechanisms:3
- Controls:Wireless remote
- Folding design:Folds flat against the wall
Our verdict“For a confirmed straight-run fit, I would choose the Universal for its placement flexibility and stated outage backup, while treating curved compatibility as unverified.”
AmeriGlide Rave 2 Battery-Powered Straight Stair Lift
The Rave 2 is the more clearly defined choice for a straight staircase. Its listing names that stair type directly and describes a self-installable setup with 15 ft of track. That clarity helps a buyer rule it in or out early, though it also means I would not treat it as a curved-stair candidate based on the information provided. The Universal listing leaves stair shape unspecified, but that omission is not proof that its track bends.
For daily use, the Rave 2 brings together a swivel seat, flip-up seat and armrests, a footrest safety sensor, and wireless call stations at the top and bottom. The swivel seat can help a rider turn at the landing, while folding components can reduce obstruction when the lift is parked. Call stations mean the lift can be summoned from either end, a useful distinction from the Universal’s listed wireless remote. The 350 lb capacity is the same as the Universal, so neither has an advantage on the stated load limit.
Its battery power and self-installable design will appeal to buyers who prefer a more independent setup. However, the description does not specify how many trips the battery supports in an outage, while the Universal provides a stated figure of more than 20 trips. Nor does the listing provide details about installation time, tools, or curved-rail options. Compared with the Universal, the Rave 2 is stronger on explicit straight-stair scope and call controls, but weaker for a buyer whose priority is documented outage range or either-side placement flexibility.
Pros:- Designed for straight staircases and described as self-installable.
- Includes 15 ft of track and supports up to 350 lb.
- Swivel seat and flip-up seat and armrests support access and stair clearance.
- Wireless call stations are provided at both the top and bottom.
Cons:- The listing identifies it for straight stairs, not curved staircases.
- No battery outage-trip estimate is provided in the supplied details.
- The 15 ft track may not suit every stairway.
Best for: A buyer with a straight staircase who wants a self-installable battery-powered lift, swivel seating, and call stations at both ends.
Not ideal for: Anyone needing a confirmed curved rail, a published outage-trip estimate, or a track longer or differently shaped than the included 15 ft run.
- Staircase type:Straight
- Track included:15 ft
- Maximum capacity:350 lb
- Power source:Battery
- Installation:Self-installable
- Seat:Swivel
- Fold-up parts:Seat and armrests
- Safety and controls:Footrest safety sensor; wireless call stations at top and bottom
Our verdict“I would pick the Rave 2 for a confirmed straight staircase where self-installation and two-end call stations matter most.”
How We Picked
I compared these options against the practical questions a home buyer faces: staircase geometry, track length, capacity, power and outage behavior, installation, and features that affect everyday access. Since the request is for curved stair lifts, I gave special weight to whether the supplied information actually confirms a curved track. It does not: the Universal listing does not specify staircase type, while the AmeriGlide Rave 2 is explicitly a straight-stair lift. I therefore rank neither as a confirmed curved-stair solution.
Within the options as described, I ranked the Universal first for its broader installation flexibility and stated outage backup, then the Rave 2 for its useful self-installation and call-station package on straight stairs. This ordering reflects the available product details, not a claim that either can be adapted to a curve. I also weighed each drawback: a fixed 15 ft track may be too short or the wrong shape, the Universal needs a nearby outlet, and the Rave 2’s straight-stair scope limits where it applies. Buyers should confirm the track plan and installation requirements for their staircase with the seller or installer before selecting either.
Factors to Consider When Choosing Curved Stair Lifts For Home
Before comparing conveniences, I would confirm that a product can physically follow the staircase. The two listings here do not establish that either has a curved rail. Once the route is confirmed, track fit, power, installation, and how the seat parks become useful points of comparison.
Confirm the rail matches the staircase
A curved stairway may have a turn, intermediate landing, or change in angle that a straight rail cannot follow. The Rave 2 is explicitly for straight staircases; the Universal description does not name a stair type. Neither detail confirms curved compatibility. Ask whether the supplied rail follows the exact route, whether the quoted track is custom-built, and what measurements or site assessment are required. Do not infer curve fit from a track length alone.
Measure the full run and landing clearance
Both options list 15 ft of track. Compare that figure with the required rail path, not just the horizontal length of the stairs. A bend or landing can change the route, and the lift also needs room to park without blocking a doorway or passage. Check where the seat will stop at the top and bottom, and whether a folded seat leaves enough room for people to use the stairs.
Compare power and outage details
The Universal uses a standard AC outlet and includes a rechargeable backup rated for 20+ up-and-down trips during an outage. The Rave 2 is battery-powered, but the product details supplied here do not say how many trips are available without household power. Ask how each battery charges, how the system signals a low charge, and what operation is available during an outage. The Universal also requires an outlet nearby, which may shape where it can be installed.
Choose an installation approach you can support
The Rave 2 is described as self-installable, while the Universal listing says no wiring is required. Those statements address different parts of setup and do not tell me that either installation is suitable for every home. Confirm who installs the rail, what tools or stair attachments are needed, and whether a professional measurement or installation is recommended for your staircase. Curved rails may call for a different process than a straight run.
Match the controls and folded profile to daily use
The Universal has a wireless remote and folds flat against the wall. The Rave 2 includes wireless call stations at both ends and a swivel seat with flip-up seat and armrests. Think through where the rider will board, who needs to call the lift, and how much stair width must remain clear when it is parked. These features can make one layout more convenient than another, but they do not resolve whether the track follows a curve.
Frequently Asked Questions
Are either of these stair lifts confirmed for curved stairs?
No. The supplied details do not confirm a curved track for either product. The AmeriGlide Rave 2 is explicitly described for straight staircases, and the Universal listing does not specify its staircase type. I would ask the seller to confirm compatibility with the measured stair route before ordering.
Which option is better for a straight staircase?
For a straight staircase, the Rave 2 is the more clearly specified option because it names straight stairs and is described as self-installable. The Universal may suit buyers who value either-side placement and its stated backup-trip capacity. Both list 15 ft of track, so check that the run fits the home.
Which product provides more outage information?
The Universal listing states that its rechargeable battery backup supports more than 20 up-and-down trips during a power outage. The Rave 2 is battery-powered, but the supplied description does not give an outage-trip count. If outage operation is a deciding factor, confirm the Rave 2’s expected backup performance with the seller.
Can I install the lift myself?
The Rave 2 is described as self-installable. The Universal is described as requiring no wiring and using a standard outlet, but that does not establish that its full installation is a do-it-yourself job. Check the installation instructions, stair attachment requirements, and support available for the exact staircase before deciding.
What should I check before choosing a 15 ft track?
Measure the full rail path and confirm the track shape, top and bottom stopping points, and clearance for the parked lift. On a curved staircase, include each turn and landing in the route and ask whether a custom rail is required. A 15 ft figure by itself does not prove the product fits a particular home.
Conclusion
For a straight staircase, I would choose the Universal if a fold-flat profile, either-side placement, and a stated outage backup matter most. I would choose the AmeriGlide Rave 2 if self-installation, swivel seating, and call stations at both ends better match the household’s routine. For a home with a curved staircase, neither listing gives enough evidence to recommend it as a compatible lift; I would proceed only after the seller confirms a rail designed for that exact route.
