The Science Behind Better Sleep

Understanding sleep science helps you choose the perfect mattress.

Why Mattress Firmness Matters

Your spine has a natural S-curve. The right mattress firmness keeps your spine aligned while relieving pressure points at the shoulders and hips. Too soft and you sink; too firm and you get pressure buildup.

Recommended by Body Weight

Under 60 kg: Medium (5–6) — cushioning without sinking
60–85 kg: Medium Firm (6–7) — balanced support
Over 85 kg: Firm (7–9) — deep support, prevents sagging

The 80-D Difference

Foam density is measured in kilograms per cubic metre. Higher density means the foam is more durable, supportive, and resistant to sagging.

Standard mattresses use 32–40D foam. Bedsy uses 80-D high-density foam — more than double the industry standard.

Sleep Cycle Explained

Each night you cycle through three stages, each vital for recovery:

Light Sleep

~50% of night

Your body transitions from wakefulness. Muscles relax, heart rate slows.

🛏️ A comfortable surface reduces tossing, letting you pass through quickly.

Deep Sleep

~20–25% of night

Physical repair happens here — tissue growth, immune system boost.

🛏️ Proper spinal alignment maximises time in deep sleep.

REM Sleep

~20–25% of night

Brain processes memories and emotions. Dreaming occurs.

🛏️ Pressure relief prevents micro-awakenings that cut REM short.

Experts recommend 7–8 hours of sleep per night for adults.

Materials Guide

Memory Foam

Moulds to your shape and distributes weight evenly.

Natural Latex

Breathable • Eco-friendly • Bouncy

Made from rubber tree sap. Naturally hypoallergenic and durable.

5 Tips for Better Sleep

1
Keep your room cool
Ideal bedroom temperature is 18–22°C for deeper sleep.
2
Limit screens before bed
Blue light suppresses melatonin. Stop screens 1 hour before sleep.
3
Stick to a schedule
Go to bed and wake up at the same time every day — even weekends.
4
Replace your mattress on time
Standard mattresses last 5–7 years. High-density foam like Bedsy's lasts 10+.
5
Check your pillow height
Your pillow should keep your neck aligned with your spine. Side sleepers need thicker pillows.
