You can filter by colour, material, storage type and more to find a king bed that works with your existing furniture and floor space.
If you are upgrading from a double, use this category page to compare the footprint of each king size bed frame and decide whether to move other pieces of furniture or consider a super king size if you have the room and want even more space.
Before buying a king size bed, you need to be clear on what type of bed you want and need. Scroll on to learn more
Ottoman king size beds lift up to reveal generous hidden storage beneath the mattress area. This sneaky storage bed makes it ideal for small UK bedrooms, flats and box rooms where there is no space for extra chests or large wardrobes. The entire base can act as storage, so you can tuck away bedding, seasonal clothes and clutter.
Compared with drawer storage, king [ottoman beds] (https://www.bensonsforbeds.co.uk/beds/ottoman-beds/) typically offer more capacity and a cleaner exterior look. Gas-lift mechanisms assist with lifting, and quality frames include strong bases to support the king size mattress as well as the contents stored beneath.
King size divan bed frames are built around a sturdy base, often with optional drawers available in various configurations for different bedroom set ups. A divan king bed is a good choice if you prefer a simple, upholstered look, want integrated storage but do not need full ottoman capacity, or have limited clearance at the side of the bed for a lift-up mechanism.
Our UK divans are designed to pair with matching headboards, allowing you to choose your fabric, height and style separately while keeping a compact footprint around the mattress.
Upholstered king frames offer a soft, padded feel and a cosy, hotel-style bedroom look. They are ideal if you like to sit up in bed to read or watch TV and want a comfortable headboard to rest your back against. Wooden king size bed frames bring warmth and a timeless style, with our options ranging from rustic oak to painted finishes that suit both classic and contemporary bedroom design schemes.
Metal king beds are durable, easy to clean and great for more industrial or traditional spaces, depending on the design. When choosing between wooden, metal and upholstered, consider maintenance, the weight of the frame, and how bold you want your king size bed to appear in the room.
Before you commit to buying a king size bed, measure your space. Twice.
Make sure that the design you want will fit in the room you intend it to. Scroll on for more information on room planning ahead of purchase.
In the UK, a standard king size mattress measures 150 cm wide by 200 cm long. A double mattress measures 135 cm by 190 cm. So yes, a UK king is both wider and longer than a double, giving you noticeably more sleeping space.
A king bed frame will usually be slightly larger than the mattress to allow for side rails, the headboard and any footboard. Some compact designs keep this difference minimal, while more decorative frames can add extra centimetres all around.
For comfortable access, it helps to allow at least a small walkway on both sides of the king size bed and at the foot, so you can move around the room, open drawers and make the bed easily. Think about the swing of doors, built-in wardrobes, radiators and windows when positioning your king bed. If your room is tight, a king size bed can still work as long as you prioritise essentials and opt for smart storage within the bed frame itself. In very large bedrooms, you might also compare king with super king size options, which offer extra width while taking up more floor space.
Different bed designs result in different overall measurements even when the internal size suits a standard king size mattress. Chunky side rails, thickly padded upholstery and oversized headboards will increase the total size of the bed frame, whereas slim metal or simple wooden frames stay closer to the mattress size. Platform bases, sleigh beds and frames with built-in storage can also add length or width. Always check the full external dimensions of your chosen king size bed frame against your bedroom measurements before ordering.
As well as the fit and feel of your king bed, you’ll need to think about additional features that may be beneficial. Below, we explain some of the common buyer dilemmas you may find yourself in.
Drawer storage and ottoman storage each have advantages. Drawer king size bed frames work well if you have clear floor space at one or both sides of the bed. They provide easy access to clothes, linens and smaller items without lifting the mattress.
Ottoman storage makes more sense when you need maximum capacity or only have clear space at the foot or one side of the bed. By lifting the sleeping surface, you can use nearly the entire base for storage, which is valuable in compact UK bedrooms. If floor space is particularly limited, an Ottoman Bed is often the better choice.
Headboards and footboards define the look of your king bed and add practical benefits. Tall upholstered headboards create a hotel-inspired focal point and give back support when sitting in bed. Lower or no footboards can help a smaller bedroom feel more open and make a king size bed feel less dominant.
Many modern frames also feature extra touches such as padded side rails, integrated USB ports, adjustable slatted bases or reinforced central support bars. Good structural support under your king size mattress helps maintain comfort and durability and can further reduce partner disturbance by limiting motion transfer through the Bed Frame.
For best comfort and longevity, pair your king size bed frame with a matching king size mattress in the same standard UK size. This avoids gaps and ensures your mattress is properly supported, whether the base is slatted or a solid platform.
Some ranges offer bundle options that include both the frame and mattress, taking the guesswork out of compatibility. You can choose from a variety of mattress types – such as pocket-sprung, memory foam or hybrid – depending on how firm you like your bed and how much motion isolation you want when sharing a king bed.

A UK king size bed frame is designed to suit a king size mattress measuring 150 cm by 200 cm. The outer dimensions of the frame itself will be slightly larger, varying with the design, materials and thickness of the headboard and rails. Always check the listed external measurements to be sure it fits your bedroom.
Measure your room and mark out the footprint of the king size bed frame, including some clearance at the sides and foot. If you can still walk around comfortably, open wardrobe doors and access drawers, a king bed should fit. In smaller bedrooms, consider a slim-profile frame with integrated storage rather than bulky standalone furniture.
Some king size bed frames are sold as frame-only, while others are available as part of a set with a king size mattress. Check product details carefully: if a mattress is included, it will be clearly stated. If not, you can choose a separate king size mattress that matches your comfort preferences.
