Help & Buying Guides

How big is a king size bed?

Thinking of upgrading to a king bed? A standard king size bed boasts dimensions of 5ft x 6.6ft (150cm x 200cm/60in x 78in), helping you wave goodbye to disputes over the covers. The next step up from a double bed, a roomy king frame is a top choice for couples, people with special requirements or an individual simply looking for the best night’s sleep possible.

We also offer super king size beds, with an extra foot in width for a truly regal touch. A super king size bed is only suitable for bedrooms with plenty of room to spare. For a regular to large room, a king size bed set offers elegance, space and a night of peaceful sleep.

What are the benefits of a king size bed?

When you choose a king size bed, you choose elegance and luxury. Perfect for transforming a basic bedroom into a master suite, our king size models are the dream bed of many. But is your room big enough for a king size bed frame? Taking up a large portion of floor space, king size beds are only suited to the larger sleeping spaces.

Placing king size bed frames in smaller rooms can cause a claustrophobic atmosphere, dominating the space and reducing comfort. 12ft x 10ft is the recommended bedroom size for comfortably accommodating king beds. If your room stands up to the task, this bed frame is great for couples looking for a spacious sleeping area (with extra room for the dog to curl up).

What is the best king size bed to buy?

King size beds are the ultimate luxury, offering two people plenty of space to stretch out and relax. Because they’re around three inches longer than an average double bed, they’re ideal if you’re a little taller and want to make sure you’ve got room to relax without your feet hanging off the end of the bed. If you’ve got the room, then a king size bed is the logical choice.

There are essentially two types of king size bed frames – wooden and metal. Wooden king size bed frames give you that traditional, homely feel and are designed to last for years. But thanks to their sublime design features and the way that natural wood ages and matures, they keep their looks and are easy to maintain. Just wipe over with a cloth to remove the dust occasionally, and that’s all you need to do.

Metal frames range from mid-century retro styles to ultra-modern designs and are perfect for more contemporary interiors. To avoid those annoying squeaks and creaks, they do need to be checked over occasionally to make sure all the connecting bolts are done up tight. But apart from that, they’re just as easy to look after as wooden bed frames.

The choice is yours – if you love that cottage feel then a wooden frame or a retro metal frame is perfect. If you like clean lines and minimalist décor, a modern metal frame is best.
