What Safety Features Do Our Double–Single Bunk Beds Have?

Safety is a core feature of every double and single bunk bed MK Furnishings offer. Each bunk is built to meet the BS EN 747 safety standard, which sets requirements for structural integrity and child protection across Europe. Our bunks include full-length safety rails on the top single bed to prevent falls, along with secure staircases fitted with anti-slip treads for stable climbing. Many designs also include stair gates or enclosed steps, especially helpful for younger children navigating the upper level. The beds are crafted from MR-HDF boards, with all edges smoothed and sealed to minimise sharp contact points. These features combine to create a child-safe sleeping setup that supports both safety and ease of use for children aged six and up.

Frequently Asked Question

A double and single bunk bed features a top single bunk positioned over a full-size double bed, sleeping up to three children. Unlike standard single-over-single setups, this layout maximises capacity while keeping a compact footprint, making it ideal for shared rooms or sleepovers. These bunk beds with double on bottom and single on top are built with MR-HDF boards and reinforced with poplar slats, combining durability with a layout designed for growing families.
Each double and single bunk bed can be personalised using our Build Your Own Bed tool. You can select vinyl name decals, carved cut-out designs, staircase layouts, and drawer colour themes to match your child’s taste. These choices allow you to build a bunk bed that suits both the room’s size and your child’s personality, without compromising storage or safety.
We recommend our double and single bunk beds for children aged six years and older for the top bunk, while the lower double bunk can be used by children as young as three. All bunks are built to meet BS EN 747 safety standards and offer secure climbing features such as stairs or ladders to ensure suitability for family homes.
Yes, if the person sleeping on the lower bed weighs under 17 stone (approximately 108 kg), the structure will support adult use. These wooden double and single bunk beds are crafted with strong pine supports and poplar slats, making it suitable for occasional adult use or teen growth. Just ensure the mattress selected matches the recommended weight and frame compatibility.
Yes, all double and single bunk beds require separate mattresses for both the single and double bunks. You can choose a tight top or memory foam mattress, but we advise investing in supportive, breathable designs that maintain shape over time. A quality mattress enhances your child’s sleep quality and supports long-term spinal health.
Yes, we offer assembly for an additional cost. Each double and single bunk bed comes with clear instructions and pre-labelled parts for easy setup. If you prefer professional help, our team can assemble the bunk during delivery. This service ensures all safety rails and fixtures are installed to manufacturer standards.
Absolutely, all of our double and single bunk beds come with a 24-month warranty from the date of delivery. This covers structural defects, hardware faults, and material integrity, giving you peace of mind when purchasing a long-term sleeping solution for your child.
Delivery typically takes 8–10 weeks from the date of order. Our team will contact you three weeks in advance to confirm your availability and finalise arrangements. We also coordinate delivery with finance plans like Clearpay to ensure payments align with product arrival.
