Choosing the Right King-Size Mattress

When selecting a king-size mattress, it's important to consider your individual sleep preferences. Here are some key factors to think about:

Sleeping Position

The ideal mattress will vary depending on whether you sleep on your side, back, or stomach. Side sleepers often prefer softer options to cushion their hips and shoulders, while back and stomach sleepers may need firmer support to ensure proper alignment.

Firmness Levels

King-size mattresses come in a range of firmness levels, from soft to extra firm. Choose a firmness that meets your specific support needs and comfort preferences.

Materials and Construction

Choosing the right mattress material can impact your overall comfort and sleep quality. There are many materials that can be used in a king-size pocket sprung mattress like cotton, wool, silk, cashmere or rubber.

King-Size vs. Other Mattress Sizes

When choosing a king-size mattress, it's helpful to compare it with other mattress sizes.

A king-size mattress is significantly wider and longer than a double mattress, offering more space for couples or individuals who prefer extra room to stretch out.

A super king mattress (180cm x 200cm) is wider than a king-size mattress, but the king-size offers ample room while being a better fit for most bedroom sizes.

Frequently Asked Questions

What are the exact dimensions of a king-size mattress in the UK?

In the UK, a king-size mattress measures 150cm x 200cm (5'0" x 6'6"). These king-size mattress dimensions need a king-size bed frame, which all of our iron, brass, upholstered and wooden beds are available in. As a guide, the size works best in a bedroom of around 3m x 3m or larger, giving you room to walk comfortably around the bed and fit other furniture. It's the most popular larger size for UK master bedrooms.

How much bigger is a king-size mattress than a double?

A king-size mattress is 30cm wider and 10cm longer than a double mattress, offering more space for both individuals and couples. That extra width works out to around 15cm of additional room per person, which can transform how restful your sleep feels. The added length is particularly welcome for anyone over six foot. If you regularly share your bed, the difference is well worth considering.

Can a king-size mattress fit in a standard UK bedroom?

Yes, a king-size mattress can fit in a standard UK bedroom, but it's important to ensure the room is large enough to accommodate the extra width and length. As a rough guide, you'll want enough clearance to walk comfortably around at least one side of the bed. Measure your room before ordering and allow space for any other furniture like wardrobes or bedside tables. If you're tight on space, a double might be the more practical choice.

Do I need special bedding for a king-size mattress?

Yes, you will need bedding specifically designed for a king-size mattress. This includes king-size sheets, duvets, and covers that match the mattress dimensions. Standard double bedding will be too small and won't tuck in properly. King-size bedding is widely available, so you won't have any trouble finding designs you like.

Is a king-size mattress suitable for adjustable bed frames?

Yes, many king-size mattresses are compatible with adjustable bed frames, but it's important to check the mattress type and frame specifications to ensure compatibility. Pocket-sprung mattresses generally flex well with adjustable bases, while very firm or thick models may be less suitable. If you're unsure, get in touch and we'll happily advise on the best pairing.
