Furniture & sleep
You spend 8 hours a day on it. Spend 10 minutes understanding it.
Firmness is a feeling. Density and core type are facts.
Mattress shops let you lie down for two minutes and call it research. What decides eight years of back comfort is foam density, core construction, firmness relative to your weight and sleeping position, and how the material behaves in Indian summer heat. These guides give you the numbers to ask for and the trial-and-return terms to insist on.
Density over marketing
Foam density (kg/m³), spring count and comfort-layer thickness.
Body and posture fit
Firmness matched to your weight and side/back/stomach sleeping.
Heat and humidity
Memory foam warmth, latex breathability, monsoon mould risk.
Furniture & sleep guides — 2 decoded
Every guide ends with a short fit finder that turns your room, family size and budget into a spec sheet you can show the shopkeeper.
Ask this in the shop
- What is the foam density in kg/m³ for each layer?
- Is there a home trial, and who pays return pickup?
- What does the 10-year warranty cover — sagging depth threshold?
- How does it sleep in peak summer without AC?
