Single-Over-Double or Three-Tier?
A single-over-double triple bunk combines a standard UK single sleeping space with a double bed underneath. This configuration works well when the lower bed may be used by a couple or when one sleeper benefits from additional room. The Holt, Kelling and Langham all provide this layout, with each model supporting users weighing up to 25 stone per sleeping position.
A three-tier bunk provides three separate single sleeping spaces within a single-width footprint. The Bircham uses a steel frame, while the Burnham provides a solid pine alternative. These designs are particularly useful in shared bedrooms, guest accommodation and other spaces where three individual beds are required without using the floor area of three separate frames.
Heavy-Duty Triple Bunk Beds for Adults
Every model in this collection is suitable for adult use, with individual weight capacities ranging from 20 to 25 stone per sleeper. The range includes strengthened metal frames and substantial wooden designs, allowing you to choose according to the required sleeping configuration, room dimensions and preferred finish.
Weight support applies separately to each sleeping position. Always check the limit for the individual model and pair the frame with mattresses that provide suitable support for their intended users. Our triple bunk beds are tested to meet BS EN 747 safety requirements when correctly assembled and used according to the supplied instructions.
Room Height and Access Planning
Measure the available floor area and ceiling height before selecting a triple bunk bed. Single-over-double models in this collection measure between 161cm and 166cm high, while the three-tier designs measure 198cm or 210cm high. Allow adequate clearance above the upper mattress so the sleeper can sit up comfortably without being too close to the ceiling.
You should also leave sufficient space around the ladder for safe access. Ladder placement differs between models, so check the individual product specifications and consider doors, wardrobes, radiators and other furniture when planning the layout.
Choosing the Correct Mattresses
Mattresses are not included as standard but compatible options can be added when ordering. Single-over-double models require one standard UK single mattress and one standard UK double mattress, while three-tier models require three standard UK single mattresses. You can view our own bunk bed mattresses which conform to the correct depth.Â
Mattresses used on the upper levels must not exceed 15cm in depth. This ensures that the safety rails remain at an appropriate height above the mattress. Triple bunk beds are not suitable for children under six years old, and the supplied guard rails must always be fitted.
Frequently Asked Questions
Are triple bunk beds suitable for adults?
Yes. Every triple bunk bed in this collection is suitable for adult use, supporting up to 20 or 25 stone per user depending on the model. Each frame is tested to meet BS EN 747 safety requirements, but always check the individual product’s weight capacity and dimensions before ordering. Upper bunks are not suitable for children under six.
Should I choose a single-over-double or three-tier triple bunk bed?
A single-over-double bunk provides a standard single sleeping space above a double, making it suitable when the lower sleeper needs more room or the bed may accommodate a couple. A three-tier bunk provides three separate single sleeping positions within a single-width footprint. Before choosing, compare the bed’s overall height with your ceiling height and allow enough clearance for safe access to each level.
Are mattresses included with triple bunk beds?
Mattresses are not included as standard, but compatible options can be added when ordering. Single-over-double models require one standard UK single mattress and one standard UK double mattress, while three-tier models require three standard UK single mattresses. The top-bunk mattress must not exceed 15cm in depth so the guard rails remain at a safe height.
