You'll spend roughly a third of your life on your mattress, yet it's often one of the most rushed furniture purchases people make. Getting it right has a bigger impact on your health, sleep quality and daily energy than almost any other item in your home. Here's how to choose wisely.

Understand the Main Mattress Types

Most mattresses on the market fall into one of four categories:

  • Pocket-sprung: Individually wrapped springs that respond to your body independently, offering excellent support and breathability.
  • Memory foam: Contours closely to your body shape, relieving pressure points, though it can retain more heat.
  • Hybrid: Combines pocket springs with a foam comfort layer — a popular middle ground offering support and contouring.
  • Latex: Naturally breathable, responsive and durable, with a slightly bouncier feel than memory foam.

Firmness Is Personal — But Follow These Guidelines

Firmness preference depends on your body weight and sleep position. As a general rule, side sleepers benefit from a medium-soft mattress that cushions the shoulders and hips, back sleepers do well with medium-firm support, and front sleepers usually need a firmer surface to prevent the hips sinking too low.

Consider Motion Isolation If You Share a Bed

If you sleep with a partner, look for a mattress with good motion isolation — pocket-sprung and memory foam designs typically absorb movement far better than traditional open-coil sprung mattresses, meaning you're less likely to be disturbed when your partner turns over or gets up.

Getting the Size Right

  • Single (90x190cm): Suited to children's rooms or compact guest rooms
  • Double (135x190cm): A comfortable option for one person or a snug fit for two
  • King (150x200cm): The most popular choice for couples, offering genuine personal space
  • Super King (180x200cm): Maximum space for couples, families with young children, or anyone who simply wants room to stretch out

Don't Skip the Trial Period

Most reputable mattress retailers now offer a trial period of 30–100 nights. Your body typically needs at least two to three weeks to adjust to a new mattress, so don't judge it after the first night — but do make full use of any trial and return policy if it's genuinely not right for you.

A good mattress should be replaced roughly every 7–8 years — sagging, lumps or waking up with aches are all signs it's time for a change.

Matching Your Mattress to Your Bed Frame

Make sure your chosen mattress is compatible with your bed base — sprung slatted bases suit most mattress types, but very soft memory foam mattresses generally perform best on a solid or narrow-slatted base for even support.
