Frequently Asked Question

A Triple Bunk Bed is a bed frame designed to hold three separate beds stacked vertically or arranged compactly to save space. It provides three sleeping areas within a small footprint, ideal for rooms with limited space. The frame supports all three beds securely, often including ladders and safety rails for upper bunks. Triple bunk beds maximize sleeping capacity while minimizing floor space, making them suitable for shared bedrooms or dormitories.
Yes, all triple bunk beds require mattresses, typically in the 90 x 190 cm twin size for each bunk. Some configurations, like those with a double bottom bunk or trundle, may also use a 140 x 190 cm mattress for the lower tier. Choose from tight top or memory foam options to ensure proper spinal support and all-night comfort.
Yes, assembly for our all triple sleeper bunk beds is available at an additional cost. Given their size and complexity, professional installation ensures fast, secure setup. If you prefer to assemble yourself, every triple bunk bed includes detailed instructions to guide you efficiently.
Children aged 3 and older can safely use the bottom bunk, and children aged 6 and above are best suited for the top bunk. These recommendations follow safety standards to ensure secure, comfortable use. Younger children will benefit from toddler or cabin beds as a lower sleeping option until they’re ready for raised bunks.
Children access upper bunks using sturdy staircases or ladders designed for grip and balance. To descend, they use the same stairs or ladders, or in some models, a built-in slide offers a fun, safe alternative.
You can personalise triple bunk beds with vinyl name decals, themed cut-out designs, and drawer colours to match your child’s style and room décor, creating a unique sleeping space. To explore all available options and design a bed that suits your space and needs, use our Build Your Own Bed tool to customise your triple bunk bed online.
Are Triple Bunk Beds Safe For Adults? Yes, our triple bunk beds support adults up to 17 stone (108 kg). Constructed with moisture-resistant engineered wood, Poplar slats, and pine supports, they offer reinforced strength for children and occasional adult use.
All triple bunk beds come with a 24-month warranty covering manufacturing defects and structural issues, giving you peace of mind about product quality and durability.
Our triple bunk beds are made to order with delivery typically in 8 to 10 weeks. We’ll contact you three weeks before delivery to confirm availability, ensuring a smooth, timely handover.
