What size is a shorty mattress?

Shorty mattress dimensions are 175 x 75 cm (roughly 5'9" x 2'6"), making them both shorter and narrower than a standard single mattress. A 175cm mattress length and 75 cm width keep the mattress footprint small while offering plenty of room for most children and teenagers.

How thick is a shorty-size mattress?

Shorty mattresses range from 10 cm to 20 cm thick. For bunk beds, mid-sleepers, and high-sleepers, stick to a maximum of 16 cm. This ensures the mattress is lower than the safety rails. Thinner options (10 to 13 cm) work well for top bunks or spare beds that don't get much use, while thicker shorty mattresses (15 to 20 cm) are more comfortable for teens or adults and everyday use.

What bed sizes can a shorty mattress be used with?

Shorty mattresses are specifically designed for shorty beds that perfectly fit the mattresses' 175 x 75 dimensions. Bunk beds, cabin beds and high sleepers often use shorty bunk bed mattresses on both levels, as the compact size means proper safety clearances. Make sure to measure your bed frame properly first before purchasing a shorty mattress.

Are shorty mattresses suitable for adults?

Shorty single mattresses are better suited for children and teenagers, but adults can use them depending on their height. The 175cm mattress length fits adults up to about 5'7" without feet dangling off the edge. Adults sleeping on a shorty mattress should opt for firmer and thicker options (15 to 20 cm). This gives better support and lasts longer. For taller adults or anyone who likes more room, explore our range of standard single mattresses instead.

Types of shorty mattresses

• Foam shorty mattresses: These are lighter, more affordable, and easy to flip, offering basic support. They’re ideal for guest beds or younger children who don’t need extra features.
• Memory foam shorty mattresses: A shorty memory foam mattress moulds to the body, easing pressure points, supporting growing children, and reducing movement disturbances for restless sleepers.
• Latex shorty mattresses: Naturally hypoallergenic and breathable, they retain their shape for years, perfect for children with allergies or sensitive skin.
• Pocket sprung shorty mattresses: Feature individually wrapped springs that move in isolation, matching your body's shape and reducing motion transfer.

What firmness levels do shorty-size mattresses come in?

Shorty mattresses come in several firmness options to suit different preferences and sleeping positions.

• Soft shorty mattresses: Feel plush and cushioned, making them ideal for lighter children or side sleepers who need softer support at the shoulders and hips. They’re less suitable for stomach sleepers or anyone who needs firmer back support.
• Medium-firm shorty mattresses: The most versatile option. Medium-firm shorty mattresses suit combination sleepers who switch positions at night. They work for most children and teenagers without feeling too hard.
• Firm shorty mattresses: Offer strong support and keep the spine aligned. They’re best for back and stomach sleepers, as well as heavier individuals or anyone who sinks too far into softer mattresses.
