Sized for kids’ rooms, guest rooms and small spaces

A single mattress measures 92cm wide by 188cm long, the standard Australian single size, so it drops straight onto a standard single bed base. That compact footprint suits kids’ rooms, guest rooms and studios where every centimetre counts. Heights run from 23cm to 28cm depending on the model, so it’s worth checking your fitted sheets before you buy.

Kloudcell® comfort with support where it counts

Every single mattress in our range is built around Kloudcell®, our signature comfort foam, which cushions pressure points at the shoulders, hips and knees while staying supportive under your back. Underneath sits a zoned support core, with select models using three targeted zones and others stepping up to five for more tailored support. Want to fine-tune the feel? Select models have a flippable comfort layer, so you can unzip the cover and switch between two firmness feels at home. Our mattress quiz can help you find the right one.

FAQs about single mattresses

What should I consider when buying a single bed mattress?

Consider factors such as your comfort preferences (extra firm or medium mattress), the materials used, your budget, and whether you want features such as hypoallergenic properties or cooling technology.

Do single beds have weight limits?

Yes, weight limits can vary depending on the bed frames and mattress type. Generally, they are designed to comfortably support one adult; consult the manufacturer or retailer for exact limits.

How firm or soft is the single mattress, and is it suitable for my sleeping position?

The firmness of a single mattress can vary widely, ranging from medium firm to firm. The ideal firmness level depends on your personal preference and sleeping position. 

Side sleepers often benefit from a medium-firm mattress that cushions the shoulders and hips, while back and stomach sleepers may prefer a firmer surface to maintain proper spinal alignment.

Are there any specific care instructions or maintenance requirements for the mattress?

To maintain your single mattress in optimal condition use a mattress protector to guard against spills and stains, and vacuum the surface regularly to remove dust and allergens. Avoid jumping on the mattress to prevent damage to the internal structure.
