Common Questions

Sleep & Mattress FAQ

Answers to the questions we hear most often at our Perth showroom.

How often should you replace your mattress?
Most mattresses should be replaced every 7 to 10 years. High-quality pocket spring and latex mattresses, such as those in the DeRUCCI range, are engineered for a minimum 10-year lifespan with proper care. Signs it is time to replace include visible sagging, persistent morning stiffness, or waking frequently during the night.
What is the best mattress firmness for back pain?
Research published in The Lancet (2003) found that medium-firm mattresses significantly reduce chronic lower back pain compared to firm mattresses. A medium-firm mattress supports the natural curvature of the spine while relieving pressure at the hips and shoulders. Those with specific conditions should consult a physiotherapist or sleep specialist before purchasing.
What is an AI mattress and how does it work?
An AI mattress uses embedded sensors and adaptive technology to map your body's pressure points in real time, automatically adjusting support zones as you move through sleep cycles. DeRUCCI's T11+ AI Mattress uses this technology to deliver personalised spinal support throughout the night, without manual adjustment.
What is the difference between pocket spring and memory foam mattresses?
Pocket spring mattresses use individually wrapped coils that move independently, providing targeted support and minimising motion transfer between sleep partners. Memory foam mattresses conform to the body's shape, offering pressure relief but retaining more heat. Many premium mattresses, including several in the DeRUCCI range, combine both technologies in a hybrid construction.
How do I choose the right mattress size?
For couples, a Queen (153 x 203 cm) is the minimum recommended size, while a King (183 x 203 cm) provides more personal space. Single sleepers are well-suited to a Double (138 x 188 cm). Super King (203 x 203 cm) is ideal for maximum space. Always measure your bedroom before purchasing.
How long does a luxury mattress last?
A high-quality luxury mattress, particularly those using natural latex or premium pocket spring systems, can last 10 to 15 years with proper care. DeRUCCI mattresses carry a 5-year structural warranty and are engineered for a minimum 10-year lifespan. Using a quality mattress protector and rotating your mattress every six months significantly extends its life.
