King Mattresses

Remember that feeling when you first get to a posh hotel and jump into the luxury king size bed? There’s nothing quite like it – the bed feeling as big as a swimming pool and comfy as a cotton wool cloud! That’s why, if you have the space in your bedroom, it’s worth investing in your own king size mattress.

What size is a king size mattress?

King size mattress dimensions are 5 feet wide and 6 feet 6 inches long, or 150cm wide and 200cm long. So they are the same length as a super king, but 30cm narrower. This makes king size mattresses ideal for those that need extra leg space but can’t fit a super king in their bedroom.

Why choose a king size mattress?

A king size mattress has several advantages and can be the perfect choice for a variety of people. The main advantages are:
• Space – As mentioned, space is the ultimate reason you should choose a king size bed. Whether that’s for luxury purposes or because you find you struggle to sleep well on a smaller mattress, a king size mattress can give you that bit of extra room
• Variety – Because they’re so popular, king size mattresses come in a variety of designs from memory foam to traditional spring to natural. There are plenty of options available in our king size mattress range.

What king size mattress is best?

With a wide array of options, it’s not always easy to say which is the best king size mattress; a lot is based on personal preference. So we’ve put together a quick guide to the various types of king size mattresses available.

In general, there are three main types of mattress; pocket spring, traditional spring, and memory foam. Most bed and mattress manufacturers make all three types, but there may be differences in the manufacturing process and cost.

Pocket spring mattresses

This type is currently the most popular type of mattress available. Providing great support, a king size pocket spring mattress is not as warm as some other types, allowing you to keep cool during the night. Each spring is independent, meaning the mattress responds perfectly to your sleep position and movement.

Traditional spring mattresses

A King size traditional spring mattress is usually the cheapest option, making them great for those on a budget. However, this doesn’t mean that they lack quality. They are often hand-tufted and feature edging to prevent fall-out. This is a good choice for those looking for a king size mattress for a bad back and other aches and pains, as they’re frequently available in medium to very firm comfort levels. The firmer options tend to have good back alignment properties, which is perfect for those who need spinal support.

Memory foam mattresses

This type of mattress has been popular for a while now. That’s because a king size memory foam mattress features advanced technology designed to maximise your sleep experience. On contact with your body, the mattress will soften and respond to your sleep position. This makes these mattresses great for keeping you comfortable all night long, helping with a variety of sleep-related health issues.

Outside of the three main king size mattress types, there’s also plenty of options for more bespoke designs. For instance, there are natural king size options, which are designed with the environment in mind. There are also zip-and-link king size mattresses, which can be split in half, allowing for different comfort levels on either side.

Choosing a king-size bed is an important investment – one that’s going to last for years. That’s why we want to make sure you get the very best. Dreams 40-night guarantee gives you the option to swap your mattress if after 30 days you’re not quite convinced.
