Which mattress firmness actually helps back pain?

Short answer
Medium-firm — roughly 6 to 7 on a 10-point scale — is what most clinical guidance supports for general lower back pain, because it supports the spine without letting the hips sink. Side sleepers and lighter people should lean softer (5-6), back and stomach sleepers and heavier people firmer (7-8). Very hard mattresses are a common mistake in Indian homes.
- Firmness is comfort; support comes from the core layer's density and thickness.
- Foam density of 32-40 kg/m³ in the support layer lasts far longer than cheaper 24 kg/m³ foam.
- Body weight changes what 'medium-firm' feels like — a 90 kg sleeper needs a firmer rating for the same feel.
Firmness by position and weight
| Sleeper | Firmness (1-10) | Type that usually suits |
|---|---|---|
| Side, under 60 kg | 5-6 | Memory foam or soft pocket spring |
| Side or back, 60-85 kg | 6-7 | Medium-firm foam / hybrid |
| Back or stomach | 7-8 | Firm foam, latex, bonnell spring |
| Above 90 kg | 7-8 | High-density foam or pocket spring hybrid |
Specs worth reading
- Total thickness: 6 inches minimum, 8 inches for anyone above 85 kg.
- Support-layer density: 32-40 kg/m³ high-resilience foam.
- Pocket spring count: 700+ for a queen size means better contouring.
- Trial period and warranty: a 30-100 night trial is now standard from Indian brands.
Common follow-up questions
Is a hard mattress better for back pain?
Usually not. A very hard surface leaves a gap under the lower back and concentrates pressure on the shoulders and hips. Medium-firm suits most people with back pain.
Does memory foam get too hot in India?
Plain memory foam does retain heat. Gel-infused, open-cell or latex layers, plus a breathable cover, handle Indian summers much better.
