King Single Mattresses

Give Yourself Room to Rest With King Single Mattresses

Too cramped on a standard single but short on space for a double? King single mattresses give you that extra room to sleep comfortably without taking over your bedroom.

At Amart, we offer a wide range of king single options to suit every budget, sleep style, and preference across Australia. From trusted brands to various firmness levels, there's a mattress designed to help you rest easy and wake up ready for the day!

What is the size of a king single mattress?

In Australia, a king single size mattress typically measures 107cm wide by 203cm long. This makes it longer and wider than a standard single, which sits at 92cm by 188cm.

It's also longer than a long single, which has the same width as a standard single but stretches to 203cm in length. This extra room makes the king single bed size perfect for anyone who needs more space without moving up to a double bed.

Finding the sweet spot between single and other mattress sizes

So how does a king single bed compare to other popular options? Double mattresses measure around 138cm by 188cm, making them wider but shorter. Queen mattresses sit at 153cm by 203cm, offering more width for couples.

If you want even more space, a super king stretches to 203cm by 203cm for the ultimate luxury. The king single fits perfectly between a standard single and these larger sizes, giving solo sleepers extra comfort without overwhelming smaller bedrooms.

Can you comfortably sleep on a king single as an adult?

Absolutely! The 203cm length suits most adults comfortably, and the 107cm width gives you enough room to stretch out without feeling cramped.

This makes it ideal for guest rooms or solo sleepers who want more space than a standard single offers. Choosing the right mattress in this size means you get all the comfort and support you need without taking up too much floor space.

Who benefits most from a king single?

This size works beautifully for a variety of sleepers and spaces. If you value a high-quality mattress that fits your lifestyle, a king single could be the answer. Many options come as a mattress in a box for easy delivery and setup.

They’re the ideal choice for:

• Teenagers: Growing kids need the extra length and width to sleep comfortably as they get taller.
• Solo adults: Single sleepers who want more room to stretch without upgrading to a double.
• Guests: Offers visitors comfort without crowding smaller spare bedrooms.
• Budget-conscious buyers: Affordable pricing with generous space makes it a great value for money.

How firm should your king single mattress be?

The mattress feel you choose depends on your sleep style and comfort preferences. Finding the right firmness helps you wake up refreshed instead of sore. Your ideal option depends on a few key factors:

• Plush mattress: Soft and cushiony, perfect for side sleepers who need pressure relief on shoulders and hips.
• Medium mattress: Balanced support for most sleepers, great if you switch positions during the night.
• Medium-firm mattress: Popular choice for back sleepers who need support without feeling too rigid.
• Firm mattress: Solid support for stomach sleepers and those who prefer minimal sinkage.
• Extra firm mattress: Maximum support with almost no give, suited to heavier body types or those who like sleeping on top of the mattress rather than sinking in.

Materials that make a king single comfortable

The mattress type you choose affects how well you sleep and wake up feeling. Different materials offer unique benefits for pressure relief and support.

Consider what works best for your body:

• Memory foam mattress: Moulds to your body shape, relieving pressure points around shoulders and hips for a cradled feel.
• Hybrid mattress: Combines foam layers with springs for balanced comfort and durability across different sleep styles.
• Latex mattress: Offers responsive bounce with firm support, great for keeping your spine aligned while staying cool throughout the night.
• Pocket spring mattress: Independent coils respond to movement and provide targeted support where you need it most.
