When it comes to getting a good night's sleep, choosing the right mattress matters more than most people realise. The mattress you sleep on every night directly affects your spinal alignment, pressure relief, and overall sleep quality — and since everyone sleeps differently, there's no single perfect mattress for everyone.
Here's a straightforward guide to help you find the right match for your sleeping style.
Side Sleepers — Prioritise Pressure Relief
Side sleeping is the most common position in New Zealand, and it places the most pressure on the shoulders and hips. A mattress that doesn't relieve that pressure will leave you waking up stiff and sore.
What to look for: A medium to medium-soft mattress with good contouring properties. Pocket spring mattresses with a quality foam comfort layer, or memory foam options like the Align range, work particularly well for side sleepers — they allow the shoulders and hips to sink slightly while keeping the spine in a neutral position.
The key balance: Too firm and your hips and shoulders are pushed upward, creating pressure points. Too soft and your spine drops out of alignment. Medium or plush is usually the sweet spot.
Back Sleepers — Focus on Support and Spinal Alignment
Back sleepers don't experience as many pressure points as side sleepers, but they need consistent support across the lower back to prevent it from sinking out of alignment overnight.
What to look for: A medium to firm mattress that keeps the spine neutral without feeling rigid. A quality pocket spring mattress — like the Raglan in medium or firm — provides the responsive, even support back sleepers need, with enough comfort in the top layers to avoid pressure on the tailbone and shoulders.
The key balance: A mattress that's too soft will let the lower back sink too deeply, causing misalignment and morning stiffness. Firm or medium firm is generally the best starting point for back sleepers.
Stomach Sleepers — Choose Firm Support
Stomach sleeping puts the most strain on the spine of any sleep position — particularly the lower back and neck. A mattress that's too soft will cause the midsection to sink, creating an uncomfortable arch that builds tension through the night.
What to look for: A firm or extra-firm mattress that keeps the body flat and the spine neutral. Simply Beds stocks extra-firm options for those who need maximum support in this position. A thinner pillow is also worth considering to keep the neck in a more neutral position.
The key balance: Firmness is non-negotiable for stomach sleepers. Anything too soft and the spine will curve, leading to lower back discomfort that builds over time.
Combination Sleepers — Look for Versatility
If you shift positions through the night — side to back, back to stomach — you need a mattress that adapts without compromising support in any position.
What to look for: A medium-firm mattress with a responsive feel. Pocket spring mattresses are particularly well suited to combination sleepers because of their natural responsiveness — they adjust as you move rather than holding you in one position. For couples who move independently, a zip-together king single combination also means each person can have a different feel on their side.
The key balance: Avoid anything too soft or too contouring — you need a mattress that transitions smoothly between positions without creating pressure in any of them.
A Few Extra Things Worth Knowing
Body weight matters. Heavier sleepers generally need a firmer mattress to prevent excessive sinking and maintain support. Lighter sleepers often find a softer feel more comfortable and better for pressure relief.
Sharing a bed? Motion isolation is worth considering — pocket spring and memory foam both handle partner movement well. Our zip-together mattress sets let couples choose different firmness levels on each side without compromising either person's sleep.
