Why you cannot trust most of what you read
Most mattress marketing aims at one thing: separating the comfort feel in the showroom from the spec on the warranty card. A mattress can feel identical to one twice as durable if the surface quilting is luxurious enough. The way other brands hide weak cores is by leaning hard on words like premium, ortho, hotel-grade, NASA technology and 7-zone — words with no fixed technical meaning. The way you protect yourself is by ignoring all of them and asking for numbers instead.
The seven numbers that actually matter
These are the specs we use internally when we engineer a mattress. They are the specs you should ask any brand to share before you buy.
1. Density of the support core (kg/m³). The single best predictor of how long a foam mattress will hold its shape. For Indian conditions, look for 32 kg/m³ or higher in the support core. Below 28 kg/m³ is fine for low-cycle uses (guest rooms, decorative cushions) but will sag within two to three years of daily use.
2. IFD or ILD (firmness). The force needed to compress the foam by 25% of its thickness. Density measures durability; IFD measures firmness. Two foams at the same density can feel completely different. A brand that quotes only firmness ("medium" or "firm") without density is hiding the durability conversation.
3. Foam type for each layer. Bonded foam, HR (high-resilience) foam, memory foam and PU foam all have different durability and feel profiles. A mattress is usually a sandwich of two or three; ask for the spec of each layer, not just the top one.
4. Total thickness. Under 70 kg sleeper weight, 4–5 inches is sufficient. 70–90 kg needs 5–6 inches with a denser core. Above 90 kg needs 6–8 inches with HR or bonded foam — thinner mattresses bottom out under heavier loads.
5. Warranty period and what it actually covers. A 10-year warranty that only covers manufacturing defects in the foam is much weaker than a 7-year warranty that covers sag over 1.5 inches. Read the small print, not the headline number.
6. Cover and quilting material. Cooling fabric, jacquard quilting, knit covers — these affect surface feel and breathability but not service life. Useful to know, not decisive.
7. Country of manufacture and factory disclosure. A mattress made in a small Indian factory with documented quality processes is usually a safer buy than one made in an unnamed location with marketing-heavy branding. Brands that hide where their products are made are usually hiding something else too.
Five marketing claims to ignore
These phrases sound technical but mean almost nothing. When a brand leans on them without sharing the numbers above, take it as a warning.
"Orthopaedic" or "ortho-firm". No regulatory definition. Any mattress can be called ortho. What matters is the density and firmness of the support core, not the word on the label.
"NASA technology" or "memory foam developed for astronauts". Memory foam has been a commodity since the 1980s. Every brand can buy it. The variant matters (closed-cell vs open-cell vs gel-infused), the marketing claim does not.
"7-zone support". Real zoning exists in pocket-spring mattresses and some HR foam designs, but the term gets stuck on flat-foam mattresses where it means nothing. Ask the dealer to show you the actual zoning if you care.
"Hotel-grade comfort". Most hotels buy mid-density bonded foam for cost reasons. "Hotel-grade" is not a quality tier — it is often a quiet downgrade.
"Anti-bedbug, anti-microbial, anti-stress, anti-ageing". These are surface-cover treatments that wash out over time. They are nice to have, not buying-decision factors.
A buying conversation that protects you
Walk into any mattress dealer with this script. The right dealer will answer all of it directly. The wrong one will deflect to feel and marketing.
"What is the density of the support core in kg/m³? What is the IFD? What materials are in each layer, top to bottom, with their thicknesses? How long is the warranty and what specifically does it cover — does it cover sag below 1.5 inches? Where is this mattress made? Can I see the warranty card before I pay?"
If you get straight answers, the brand is being honest with you. If you get marketing language back, walk away.

FAQ
What is the most important spec when comparing mattresses?
Density of the support core in kg/m³ is the single best predictor of how long a foam mattress will hold its shape. For Indian conditions, look for 32 kg/m³ or higher. Brands that quote firmness but not density are usually hiding the durability conversation.
Is "orthopaedic" a real mattress category?
No. "Orthopaedic" has no regulatory definition in India. Any mattress can be marketed as orthopaedic. What actually matters is the density and firmness of the support core, not the word on the label.
Why do most online mattress brands cost more than dealer-sold mattresses?
Direct-to-consumer brands carry the cost of paid online marketing, free trial returns, and customer-acquisition spend — usually 25 to 40 percent of the retail price. Dealer-sold mattresses from a manufacturer with no D2C e-commerce channel typically deliver the same spec at a lower price because the marketing layer is missing.
How do I check if a mattress brand is hiding spec information?
Ask three questions: what is the density of the support core in kg/m³, what is the warranty period and what does it specifically cover, and where is the mattress manufactured. Brands that deflect on any of these are usually hiding something. Honest brands answer all three in one minute.
How long should a well-made foam mattress last?
A foam mattress with a 32 kg/m³ or higher density support core should last 8–10 years of daily use under normal household conditions. A bonded foam core at 80–100 kg/m³ should last 10–12 years. Memory foam comfort layers usually outlast their warranty when paired with a quality core.
