Foamico Mattress

If you have ever shopped for a mattress in India — online or in store — you have almost certainly come across the term "HR foam." It appears on product pages, in showroom descriptions, and in recommendations from mattress sales teams across the country.

But what exactly is HR foam? How is it different from ordinary foam? And why has it become the dominant mattress material in the Indian market?

In this guide, Foamico gives you the complete, honest picture — from the chemistry and engineering that make HR foam unique, to who it is best suited for, to how to verify you are actually getting genuine HR foam and not a mislabelled substitute.

Quick Answer: HR foam stands for High Resilience foam — a specialised type of polyurethane foam engineered with a rubber compound additive and open-cell structure that gives it an instant, spring-like bounce-back. Unlike memory foam which sinks slowly, HR foam responds immediately to pressure and supports the body without the sinking sensation.

What Does "High Resilience" Actually Mean?

Resilience in foam refers to its ability to spring back to its original shape after being compressed. The higher the resilience, the faster and more completely the foam recovers.

Standard polyurethane foam — the material used in most low-to-mid-range mattresses — has relatively low resilience. It compresses under your body weight and recovers slowly. Over time, it develops permanent body impressions and begins to sag.

HR foam is engineered to have significantly higher resilience — meaning it springs back quickly and completely after each compression, even after years of daily use. This is what makes it inherently more durable and more supportive than standard foam.

The Technical Definition: What Qualifies as True HR Foam

This is where most mattress guides fall short — and where understanding the technical details protects you as a buyer.

True HR foam is defined by two specifications:

•Density: typically 30 to 60 kg/m³ for mattress applications

•Support Factor (Compression Modulus): must be 2.4 or higher — this is the critical number

The Support Factor measures how much the foam's resistance increases as you compress it more deeply. A high support factor means the foam provides increasing pushback as your body sinks deeper — preventing you from bottoming out and ensuring proper spinal support regardless of your body weight.

Standard PU foam has a support factor below 2.4. Any foam below this threshold is not genuinely high-resilience foam — no matter what the label says.

Foamico Tip: Mislabelling of HR foam is widespread in the Indian mattress market. Always ask the manufacturer to provide the Support Factor specification in writing. If they cannot or will not provide it, that is a sign the product may not meet the true HR foam standard.

How Is HR Foam Made? The Chemistry Behind It

HR foam is manufactured through a controlled chemical reaction between two primary compounds:

•Polyol: provides the foam's flexibility, softness, and comfort

•Diisocyanate: provides the foam's structural rigidity and firmness

The defining difference from regular PU foam: HR foam incorporates a rubber compound additive during this reaction. This additive creates a different cellular architecture — an open-cell structure where the foam's internal cells are interconnected rather than sealed off from each other.

This open-cell structure is responsible for two of HR foam's most important properties:

1.Superior breathability — air flows freely through the foam

2.Rapid response time — the cells can decompress and return to shape almost immediately after pressure is removed

How Does HR Foam Feel?

If you have ever slept on memory foam, you know the experience of slowly sinking in as the foam warms up around you. HR foam is the opposite.

When you lie on HR foam, the surface pushes back against your body weight immediately. There is a firm, supportive lift — a gentle bounce. You feel supported on top of the mattress rather than enveloped by it. Changing positions is effortless because the foam responds instantly to your movement.

Many people describe HR foam as feeling like a much better version of a traditional spring mattress — supportive and firm, but with more comfort and pressure relief, and none of the squeak.

Why HR Foam Dominates the Indian Mattress Market

No other mattress material matches HR foam's combination of properties for the specific context of Indian buyers:

Climate Suitability

India's climate is predominantly warm to hot, with high humidity in coastal and tropical regions. Traditional memory foam's heat retention makes it uncomfortable in rooms without consistent air conditioning. HR foam's open-cell structure allows significant airflow, keeping the sleep surface considerably cooler.

Long Ownership Cycles

Indian consumers typically keep mattresses for 10 to 15 years — longer than most Western markets. HR foam's durability and resistance to permanent compression makes it well-suited to this expectation. Standard foam mattresses often sag visibly within 4–5 years under this usage pattern.

Orthopedic Preference

There is a strong cultural preference in India for firmer, more supportive sleeping surfaces. HR foam provides this firmness along with proper orthopedic support, without the hardness of a spring mattress.

Value for Money

HR foam delivers near-latex performance in terms of support, durability, and breathability — at a fraction of the cost of natural latex. For Indian families seeking the best value from their mattress investment, HR foam is consistently the most logical choice across most budget brackets.

HR Foam Density Guide for Indian Buyers

Density	Quality Level	Best For
25–30 kg/m³	Low	Children, very light adults
30–40 kg/m³	Standard	Average weight sleepers
40–50 kg/m³	Medium-High (recommended)	Most Indian adults
50–60+ kg/m³	High	Heavy individuals (above 90 kg), firm orthopedic support

HR Foam Mattress Benefits

•Orthopedic support: Distributes body weight evenly across the sleep surface, reducing pressure concentration on the hips, shoulders, and lower back. Maintains the natural curvature of the spine in all sleeping positions.

•Superior durability: HR foam resists permanent compression far better than standard foam. A quality Foamico HR foam mattress maintains its shape and support for 8 to 12 years under normal use.

•Breathable and cool: The open-cell structure allows air to flow through the foam continuously. HR foam sleeps significantly cooler than memory foam — essential across most of India's climate zones.

•Instant response: No sinking or trapped feeling. HR foam springs back immediately when you move, making repositioning during sleep effortless.

•Temperature-stable performance: Unlike memory foam which changes feel with room temperature, HR foam maintains consistent support whether the room is warm or cold — important in India where seasonal temperature swings can be significant.

•Good [motion isolation](/blog/what-is-motion-isolation-mattress): HR foam's cellular structure absorbs body movement effectively — a sound choice for couples.

•Hypoallergenic: The open-cell structure does not provide a hospitable environment for dust mites or mould — a meaningful advantage in Indian homes.

•Versatile construction: HR foam can function as both the support core (firmer, higher density) and the comfort layer (softer, lower density) in a multi-layer mattress — making it the most versatile foam material in mattress construction.

HR Foam Mattress Drawbacks

•Less body contouring than memory foam: HR foam does not hug and mould to the body the way memory foam does. For sleepers with very specific pressure point needs — such as shoulder pain from side sleeping — the contouring of memory foam may be more therapeutic.

•Initial off-gassing: Like most foam products, a new HR foam mattress may have a faint chemical odour when first unpacked. Airing it in a well-ventilated room for 24–48 hours before use resolves this completely.

•Widespread mislabelling: Any PU foam above a certain density is frequently labelled "HR foam" in India, even without the required Support Factor of 2.4. Always request verified specifications from the manufacturer.

Who Should Buy an HR Foam Mattress?

•Back and stomach sleepers who need a firm, flat, supportive surface

•Heavier individuals (above 80 kg) who need durable foam that will not sag quickly

•Hot sleepers and those in warm Indian cities without consistent air conditioning

•Combination sleepers who need to reposition easily through the night

•Families looking for a long-term durable mattress at a sensible price

•Children and teenagers — the firm, supportive feel promotes healthy spinal development

•First-time mattress buyers who want reliable, all-round performance

•Anyone who has tried memory foam and disliked the slow-sinking, engulfing sensation

HR Foam vs. Memory Foam: Which Should You Choose?

Choose HR Foam if: you sleep in a warm room, prefer a responsive feel, sleep on your back or stomach, need firm orthopedic support, or want the best performance-to-price ratio.

Choose Memory Foam if: you sleep primarily on your side, have significant joint or pressure point pain, share a bed with a restless partner, and sleep in an air-conditioned room.

The best of both: Some Foamico mattresses combine both materials — an HR foam support core for durability and firm orthopedic support, with a memory foam comfort layer on top for pressure relief. This layered construction delivers the strengths of both materials while minimising each one's drawbacks.

Frequently Asked Questions

No — they are fundamentally different materials. Memory foam (viscoelastic foam) reacts to body heat and slowly moulds around you. HR foam reacts to pressure and springs back immediately. The feel, the science, and the ideal use cases are quite different.

Yes. HR foam is one of the most recommended materials for back pain in India. It provides firm, even weight distribution and maintains the natural curve of the spine — both critical for reducing and preventing lower back pain. Medium-to-high density HR foam is generally the best choice.

A quality HR foam mattress with a density of 40 kg/m³ or above and a Support Factor of 2.4 or higher will typically last **8 to 12 years** under normal use. Rotating it every 6 months and using a quality waterproof mattress protector will extend its lifespan further.

Yes — this is one of HR foam's most important advantages for Indian buyers. Its open-cell structure allows air to circulate freely, making it significantly cooler than traditional memory foam. It is one of the better foam choices for warm rooms and humid climates.

PU (polyurethane) foam is the broad material category. HR foam is a specific, engineered grade of PU foam with a rubber compound additive and a Support Factor of 2.4 or higher. All HR foam is PU foam — but not all PU foam is HR foam. Standard PU foam is lower quality, less durable, and provides less consistent support. HR foam is the premium tier within the PU foam category.

Yes — HR foam with medium-to-firm density is an excellent choice for children's mattresses. It provides the orthopedic support needed during critical years of physical development, resists sagging under long-term daily use, and breathes well in Indian room temperatures. *Want to experience the Foamico difference?
