⭐⭐⭐⭐⭐ Daniel Park - Boutique Gallery Manager
"We needed a staircase that was both safe and visually striking for our new art gallery. The Pro Model with aerospace-grade aluminum and custom black finish was perfect. It supports frequent foot traffic without noise, and the glossy lacquer on the steps resists scuffs surprisingly well. The modular setup allowed precise fitting into our tight corner space—no rework needed."Purchase Date: November 2024 | Usage Period: 7 months
⭐⭐⭐⭐☆ Carlos Mendez - Interior Renovator
"Used the Base Model in a small apartment renovation where space was tight. It’s affordable, easy to assemble, and looks far more premium than its price suggests. Only reason I’m not giving five stars is that the customization options required a longer lead time—about two weeks extra. But once installed, the client loved it. Great option for budget-conscious homeowners."Purchase Date: April 2024 | Usage Period: 8 months
⭐⭐⭐⭐⭐ Sophie Reynolds - Family Homeowner
"We have three kids and pets, so durability was key. We chose the Advanced Model with reinforced steel-wood treads and pine steps for a rustic feel. After six months of heavy use, there’s no sign of wear. The non-slip surface gives me peace of mind, and the cable-reinforced handrails feel rock solid. It’s also surprisingly quiet—no creaking like traditional wooden stairs."Purchase Date: January 2025 | Usage Period: 6 months
⭐⭐⭐⭐⭐ Marcus Liu - Hotel Design Consultant
"Specified the Pro Model for a boutique hotel rooftop suite. The lightweight aluminum frame reduced structural load concerns, and the 200 kg/step capacity handles luggage carts during housekeeping. Guests love the modern spiral aesthetic, and maintenance is minimal—just a quick wipe-down keeps the wood looking fresh. Worth every penny for high-end projects."Purchase Date: May 2025 | Usage Period: 1 month
