Find the perfect balance of pressure relief, spinal alignment, and dreamy comfort
Side sleeping is more than a preference — it’s a lifestyle. Roughly 60% of adults favor drifting off on their side because it naturally aligns the body and can reduce snoring. But it also means your shoulders and hips need just the right support. Too firm and you’ll feel like you’re dozing on a wooden bench; too soft and you’ll wake up with aches.
Let’s explore the top mattresses at Sleep United that deliver that Goldilocks “just right” feel for side sleepers of every budget and build.
What Side Sleepers Need
in a Mattress
Before we dive into specific models, here’s what to look for:
🎯 Pressure Relief
Side sleepers put extra pressure on shoulders and hips. A mattress that contours to curves relieves pressure and stops that “pins and needles” feeling.
🌙 Spinal Alignment
Your spine should be neutral — not bending like a banana. Good lumbar support is key.
💨 Temperature Control
Many soft foams trap heat. Look for cooling tech if you overheat at night.

Choosing the Right Firmness of Support
Here’s a quick rule of thumb:
Lightweight (Up to 68 kg/10.5 stone): Medium
Average (Up to 105kg/16.5 stone): Medium – medium/firm, 1000 – 1500 springs
Heavier (Over 105kg/16.5 stone): Medium/Firm to Firm, 1500 – 2000 springs plus
Side sleepers tend to prefer a softer feel because it cushions shoulders and hips, however the underlying support layer should be selected for the weight of the individual, the cushioning and comfort comes from the depth and materials of the top comfort layer.
