More than a bed.
As kids get older they will naturally want to spend more time in their room pursuing their interests either alone or with friends. High Sleeper Loft beds are a great way to maximise space and storage – be it a place for a screen and chair for gamers, bookshelves for avid readers or a wardrobe for the fashion conscious, high bed sleepers provide limitless design combinations for the perfect bedroom set up. Desk space will help accommodate the growing demands of study and homework and the extra room beneath the bed is great for an additional mattress during sleepovers.

Also known as loft beds, high sleeper beds are designed to make the most of vertical space. By raising the sleeping area above ground level, and they free up the entire floor underneath for desks, storage, or even a sofa bed, making it into a bunk bed. This makes them one of the most practical and multi-functional furniture choices for modern family homes.Whether you’re furnishing a child’s bedroom, upgrading to a new bed for a teenager, or simply trying to maximise space, high sleeper loft beds let you design around your child’s lifestyle and changing needs.
High sleepers are an excellent choice for growing kids, but they are best suited for:
At Cosybunks, our range of high sleeper beds UK includes designs to suit every family and room layout. Each comes with essential safety features such as guardrails, sturdy ladders or steps, and mattress height guidance (no more than 15 cm).
Safety is always the first question parents ask, and it’s the right one. High sleeper beds can be completely safe for children when designed and used correctly.
To ensure your new bed is the perfect fit, we recommend a few quick checks:
High Sleeper vs. Mid Sleeper: What’s the difference?
It comes down to height and clearance. A high sleeper (approx. 170cm+) offers full head-height space underneath, suitable for furniture like desks and wardrobes. A mid sleeper is lower (approx. 110cm–140cm) and is ideal for younger children, offering storage or play space underneath rather than a functional living area.
Is a high sleeper safe for my 6-year-old?
Yes, provided they are confident in climbing a ladder. Six is the recommended minimum age for high sleepers due to their height. For younger children, we recommend looking at our mid sleeper or standard bunk options.
How difficult is it to assemble a high sleeper loft bed?
Most high sleepers arrive flat-packed and will require self-assembly. Due to the height and weight of the frame, we strongly recommend that two people work together for safety and ease. Clear, step-by-step instructions are provided with every Cosybunks bed. If you are not confident with DIY, you may wish to consider hiring a professional assembly service with our partners at TaskRabbit.
Can I choose which side the ladder goes on a high sleeper loft bed?
Yes. Many of our models feature a 'reversible' ladder design, allowing you to mount the ladder on either the left or right side during assembly to suit your room layout. However, some specific designs are fixed to ensure structural integrity. Please check the individual product specifications to confirm.
What is the maximum weight limit for a high sleeper loft bed?
Our beds are built to be robust. While limits can vary slightly by model, most of our high sleepers are designed to safely support a user weight of up to 100kg (approx. 15 stone). This makes them suitable for older teenagers, though we always advise checking the specific limit on the product page.
Do I need a special mattress size for high sleeper loft beds?
Most of our beds take a standard UK Single mattress (90cm x 190cm). However, the critical factor is depth. To ensure the safety guardrails are effective, the mattress must not be thicker than 15cm. We offer a range of specific high-sleeper mattresses designed to offer maximum comfort within this safety limit.
Are high sleeper loft beds suitable for rooms with low ceilings?
You need to ensure there is enough headroom for your child to sit up safely in bed without bumping their head. We recommend leaving at least 60cm of clearance between the mattress surface and the ceiling. If your room has particularly low ceilings or slanted eaves, a mid sleeper might be a better fit.
How do I stop my high sleeper from wobbling?
A slight amount of movement is normal for tall, freestanding furniture, but it should never feel unstable. To ensure your bed is rock-solid:
Why is the top bunk so hot, and how can I keep it cool?
Because heat rises, the air near the ceiling can often feel a few degrees warmer than at floor level. To keep your sleeper cool:
