Maximize space and functionality with the 3-Layer Metal Bunk Bed with Pull-Out Trundle, designed for 90×190cm mattresses. This reinforced iron bed frame features a smart triple-layer structure with a smooth roller pull-out trundle, comfortably accommodating up to three sleepers—ideal for families, dormitories, shared rooms, or guest spaces. Crafted from thickened round-tube iron with multiple crossbeam reinforcements, it offers exceptional stability, supporting up to 200kg on the upper bunk and 250kg on both the lower bunk and trundle bed. Safety is prioritized with high guardrails, anti-slip steps, and protective anti-slip feet/rollers that prevent floor scratches. Silent anti-slip pads between the frame and bed boards reduce noise for a quiet, comfortable sleep experience. The flexible design allows quick switching between a standard bunk setup or a full three-person sleeping arrangement. Its modern industrial British-style structure blends seamlessly with various interiors. Easy snap-on assembly takes around 1.5–2 hours, and the eco-friendly, paint-free construction ensures an odorless, safe indoor environment.
