A mattress topper directly affects how your body rests. The thickness controls pressure relief, spinal alignment, comfort level, and airflow.
A study by National Taipei University of Technology (NTUT, 2020) found that even a 3cm topper can reduce body pressure, change muscle activity, and improve spinal alignment.
Key takeaway:
Thinner toppers = slight comfort adjustment
Thicker toppers = deeper support and pressure relief
Choosing the right thickness ensures better sleep not just a softer bed.
Getha Mattress Topper Thickness
| Thickness | Feel Level | Best For | Sleep Position | Outcome |
|---|---|---|---|---|
| 5cm | Light comfort | Slightly hard mattress | Back sleepers | Subtle softness |
| 6cm | Balanced | Daily comfort upgrade | Back & combo | Support + comfort |
| 9cm | Plush | Pressure relief | Side sleepers | Reduces shoulder/hip pain |
| 10&13cm | Deep & soft | Old/uneven mattress | All sleepers | Full transformation |
Choosing Based on Your Sleep Problem
1. Mattress Too Hard → Go 5cm or 6cm
If your mattress feels too firm but still structurally good:
- 5cm: Adds a light comfort layer without affecting support
- 6cm: Noticeably softer while maintaining spinal alignment
Best choice:
- Budget / minimal change → 5cm
- Everyday comfort → 6cm
2. Shoulder or Hip Pain → Go 9cm
Pressure points usually happen when your mattress is too firm or lacks contouring.
- 9cm thickness allows deeper compression
- Distributes body weight more evenly
- Reduces stress on joints
Best for:
- Side sleepers
- Lightweight individuals
- People waking up with soreness
3. Mattress Too Old or Uneven → Go 10&13cm
If your mattress has dips or sagging:
- A thin topper won’t fix the issue
- 10&13cm topper creates a new sleep surface
What it does:
- Masks uneven areas
- Improves comfort instantly
- Extends mattress lifespan
4. Back Pain or Poor Support → Go 6cm or 9cm
Back pain is often caused by poor spinal alignment.
- 6cm: Keeps support while improving comfort
- 9cm: Adds contouring for pressure relief
Avoid:
- Too thin → no relief
- Too thick (if too soft) → sinking
