Compare the Summer by Ingenuity Stairway+ 46W and Top of Stairs Simple to Secure metal gates by opening width, height, and stair use to pick the right barrier.
Quick answer
Choose the Stairway+ 46W if your opening is 31–46 inches wide and you want a taller 32.5-inch gate with a full-width walk-through door; choose the Top of Stairs Simple to Secure gate if your opening is 29–42 inches and you need a 30-inch gate specifically designed for top-of-stairs placement.
Width and height decide the fit before anything else
Measure your opening at the narrowest point. The Stairway+ covers 31–46 inches, while the Top of Stairs gate covers 29–42 inches. If your opening is under 31 inches, the Stairway+ won’t fit; if it’s over 42 inches, the Top of Stairs gate won’t reach. The Stairway+ is also 2.5 inches taller (32.5 vs 30 inches), which can matter for climbing toddlers or larger pets.
Neither gate lists an option for extra extension kits in the catalog, so treat the stated range as your hard limit. A gate that barely fits at maximum width may feel less solid than one centered in its range.
Stair placement changes the hardware you should expect
The Top of Stairs gate is explicitly rated for top or bottom of stairs and between rooms. The Stairway+ description emphasizes a no-threshold design and banister/stair safety, but the catalog does not specify a mounting method. If your stairs have a banister or you need a no-threshold walk-through, ask before buying; if you need a gate that is clearly labeled for top-of-stairs use, the Top of Stairs model is the safer documented choice.
Door swing and walk-through width affect daily use
The Stairway+ door opens the entire width of the gate, which makes carrying laundry or a toddler through easier. The Top of Stairs gate includes a precision fit template for faster installation, but the catalog does not state its door opening width. If frequent one-handed pass-throughs matter, the full-width door is a practical advantage; if installation speed matters more, the template is a real convenience.
Decision rules for choosing between the two gates
- Opening width: Measure the narrowest point. If it is 29–30 inches, only the Top of Stairs gate fits. If it is 43–46 inches, only the Stairway+ fits. Between 31 and 42 inches, both fit—move to the next rule. Write down the measurement before you shop; a half-inch error can rule out one gate entirely.
- Stair location: For top-of-stairs use, pick the Top of Stairs gate unless you have confirmed the Stairway+ mounting method for your banister or wall. For bottom-of-stairs or between-room use, either gate works within its width range. Top-of-stairs safety is the one place where the catalog wording should decide for you.
- Height and pet size: If you have a climbing toddler or a large dog that can clear a 30-inch barrier, choose the 32.5-inch Stairway+. If 30 inches is enough, the Top of Stairs gate saves 2.5 inches of visual height. Height is a comfort and containment choice, not a substitute for correct mounting.
- Walk-through convenience: Choose the Stairway+ if you want the door to open the full width of the gate. Choose the Top of Stairs gate if you value the included precision fit template for faster installation and do not need a full-width door. Decide which daily annoyance you would rather avoid: a narrower door or a slower install.
