Which type of single mattress filling is best for me?

Choose from a range of different mattress fillings to suit your sleep preferences:

• Pocket spring single mattresses: These are ideal for couples and restless sleepers. They feature individually wrapped springs that respond to your body's movements, reducing motion transfer and providing targeted comfort.
• Combination single mattresses: Pocket springs with foam and gel layers for ultimate pressure relief,- helping to alleviate aches and promote more restful sleep.
• Memory foam single mattresses: These offer personalised support for pressure points and spinal alignment, as memory foam absorbs movement and gently cushions the joints.
• Foam single mattresses: Made with premium foam that provides firm and stable support, these mattresses absorb motion and offer excellent durability.
• Traditional spring single mattresses: These feature a series of connected springs and an open coil system that promotes airflow to keep you cool at night. They are an excellent option for support and value for money.
• Gel single mattresses: These are specifically engineered to adjust to your body shape while keeping your temperature balanced throughout the night.
• Natural single mattresses: Crafted from natural materials like cotton and wool, these mattresses help wick away moisture, keeping you dry and comfortable throughout the night.
• Latex single mattresses: These feature a natural latex layer and offer hypoallergenic support that helps resist dust mites and allergens, promoting a healthier sleep environment.

What is the recommended thickness for a single mattress?

Our single mattresses range in thickness from 6 to 12 inches or 15 to 31cm. The correct thickness for you will vary, including your preferred level of support and firmness, and your bed frame. While thinner mattresses under 15cm are more suited to children, thicker mattresses may be more suitable for heavier individuals.

What single mattress comfort rating is best for me?

Our single mattresses come in a range of comfort ratings. The best type for you will depend on your personal preferences along with your sleep style:

• Soft mattresses are typically suited to side sleepers and those who prefer a cushioned feel that adapts to their body.
• Medium mattresses are a versatile choice for combination sleepers and ideal for those who switch sleeping positions throughout the night.
• Firm mattresses are usually best for back and stomach sleepers and those with back or pressure problems.
• Very firm mattresses offer additional support for joints and pressure points, making them perfect for anyone with pain or a higher body weight.

Are single mattresses suitable for children?

Single mattresses are perfect for children over two and are a great next step after a cot bed. Our kids' single mattresses are designed to support growing bodies, with added features like waterproof covers and anti-allergy properties for extra peace of mind.

Can a single mattress be used with a bunk or day bed?

A single mattress fits perfectly on most day beds, allowing you to choose from our range to match your comfort preferences. While most bunk beds are suitable for a single mattress, they often require a mattress depth under 15cm (6 inches) to keep your child below the safety rail. Be sure to check both the mattress and bed specifications before purchasing. Alternatively, we offer a range of bunk bed mattresses specially designed for both top and bottom bunks.

What is the typical lifespan of a single mattress?

A single mattress typically lasts 7 to 10 years, based on nightly use by an adult. However, its lifespan can vary depending on the mattress type, how it's cared for, how often it's used and the bed it sits on. Regularly rotating or flipping your mattress can help prolong its life, ensuring consistent comfort and support over time.
