Foam vs Spring Mattress

Choosing the right mattress plays a big role in how well you sleep, how your back feels in the morning, and how refreshed you are during the day. With so many options on the market, the question often comes down to: “Which mattress is better: Foam or spring?”

The truth is, there’s no single “better” option. Foam and spring mattresses are simply different types of mattresses, designed for different sleep styles, body types, and comfort preferences. In this guide, we’ll look at the key differences between foam and spring mattresses, the main types you’ll find, and how to pick the one that suits your sleep needs and lifestyle best.

Comparison Table: Foam vs Spring Mattress

To make it easier to choose between the two, let's look at the comparison table to give you a quick overview.

Feature Foam Mattress Spring Mattress
Support Type
  • Contouring support that moulds to body shape
  • Best for side sleepers (60–80 kg)
  • Provides pressure relief at shoulders and hips
  • Pushback support that resists compression
  • Best for back or stomach sleepers (85 kg+)
  • Promotes firm spinal alignment
Motion Isolation
  • Excellent: 85–90% motion absorption
  • Partner movement is barely felt
  • Ideal for couples with different schedules
  • Bonnell coils: ~40% isolation
  • Pocketed coils: ~70–75% isolation
  • Movement transfers more in interconnected systems
Temperature Regulation
  • Sleeps 2–4°C warmer due to limited airflow
  • Gel-infused foams reduce this to ~1–2°C warmer
  • Can feel uncomfortable in humid climates
  • Maintains temperature within 1–2°C of room temp
  • Open-coil structure provides natural ventilation
  • Better suited for hot sleepers
Durability
  • Memory foam (5+ lb/ft³): 10–12 years
  • Latex foam: 12–15 years
  • Basic poly foam: 6–8 years
  • Pocketed springs (13–14 gauge): 10–12 years
  • Bonnell springs: 7–9 years
  • Heavier sleepers (90 kg+) may reduce lifespan by ~30%
Noise
  • Completely silent during movement
  • Can develop squeaks after 3–5 years as coils age. 
Edge Support
  • Weak: Compresses 6–8 cm at the edges, reducing usable width by 5–10 cm on a queen mattress.
  • Strong: Compresses only 2–3 cm. Offers a firm sitting and sleeping surface edge-to-edge.
Pressure Relief
  • Excellent: distributes weight across 15–20 zones
  • Reduces peak pressure by 35–40%
  • Moderate: creates only 3–4 contact zones
  • Comfort layers can significantly improve relief
Breathability
  • Dense foam restricts airflow considerably
  • Sleeps 2–4°C warmer for ~40% of users
  • Excellent: 15–20 cm open-coil layer aids airflow
  • Vertical air circulation keeps surface cool
Weight Capacity
  • Standard foam: supports 100–120 kg per person
  • High-density foam: up to 150 kg per person
  • Standard springs: up to 100 kg per person
  • Carbon-tempered springs: 130 kg+ per person
Price Range (Queen)
  • Basic poly foam: ₹8,000–₹15,000
  • Memory foam: ₹20,000–₹45,000
  • Latex foam: ₹40,000–₹80,000
  • Bonnell spring: ₹6,000–₹18,000
  • Pocketed spring: ₹15,000–₹35,000
  • Hybrid spring: ₹30,000–₹70,000
Maintenance
  • No rotation needed for most foam types
  • Rotate every 3–6 months for even wear
Best Sleep Position
  • Side sleepers (60–80 kg): soft to medium (4–6/10)
  • Back sleepers under 85 kg: medium-firm (6–7/10)
  • Not ideal for stomach sleepers above 85 kg
  • Back sleepers (85 kg+): medium-firm to firm (6–8/10)
  • Stomach sleepers: firm spring (7–9/10)
  • Not ideal for lightweight side sleepers

What is a Foam Mattress?

Foam mattresses are one of the most popular choices due to several reasons. They are made up of three core ingredients: polyols (typically derived from petroleum oils), isocyanates (which trigger chemical reactions when combined), and a blowing agent that creates air bubbles within the foam. By carefully measuring these components, foam mattresses with varying firmness and density are produced.

Types of Foam Mattress

Types of Foam Mattress

Whether you are a Gen Z seeking the perfect nap or a millennial on the hunt for quality rest, there is a type of foam mattress for everyone.

  1. Memory Foam: Gives you personalised comfort and is perfect for those suffering from joint or muscle pain. It promotes proper spinal alignment and alleviates pressure points effectively.
  2. Latex Foam: A naturally breathable option that ensures a cool and comfortable sleep. Its inherent resistance to dust mites and allergens also makes it ideal for allergy sufferers.
  3. Gel Foam: Combines the pressure-relieving properties of traditional foam with enhanced cooling, allowing you to have a refreshing and comfortable sleep all night long.

What is a Spring Mattress?

Spring mattresses provide a classic feel at an affordable price. Their history stretches back to 1871 when the first innerspring mattress was patented. Modern technology has since transformed these beds into high-performance mattresses with excellent support and a satisfying bounce.

Types of Spring Mattress

Spring mattresses offer classic comfort and come in various styles to suit different needs.

  1. Bonnell Springs: The tried-and-true choice for everyone. Features interconnected hourglass coils that provide consistent support and a familiar bounce — ideal for those seeking a traditional sleep experience.
  2. Pocket Springs: Each coil is individually encased in fabric to minimise motion transfer. This design provides targeted, zone-specific support for a more peaceful, undisturbed sleep.
  3. Continuous Coils: A single wire forms S-shaped coils throughout the mattress, giving consistent support at an affordable price point. They offer a balanced combination of comfort and responsive bounce.

Who Should Choose Which Mattress?

Still unsure? Use the guide below to match your sleep profile to the right mattress type.

Choose a Foam Mattress if you…
  • Sleep primarily on your side and need pressure relief
  • Have joint pain, arthritis, or pressure point sensitivity
  • Share a bed with a restless partner
  • Are a light sleeper easily disturbed by movement
  • Prefer a contouring, "hugging" feel
  • Don't overheat during sleep (or invest in gel-cooled foam)
  • Weigh under 90 kg
Choose a Spring Mattress if you…
  • Prefer a firm, bouncy feel with more responsiveness
  • Sleep on your stomach or are a heavier individual
  • Tend to sleep hot and need strong airflow
  • Have back pain and benefit from targeted coil support
  • Are budget-conscious and need a durable option
  • Need strong edge support across the full mattress
  • Weigh 90 kg or above

There is no universal winner, but there is a right choice for you. If comfort, support, and uninterrupted sleep matter most, → Foam mattress. If bounce, airflow, and traditional feel matter more → Spring mattress. The key is quality construction, not just mattress type.

Conclusion

Well, we hope that sort of answers the burning question. In all fairness, it does come down to factors like personal preferences, financial conditions, physical conditions, etc. The end goal is to pick a mattress that ensures an optimal night's sleep. The decision to make a purchase should be an educated one and should be done keeping in mind your quality of sleep.

FAQs

Which is better for back pain: foam or spring? +

A memory foam mattress is generally better for back pain due to its superior body-contouring capabilities and excellent pressure relief. However, a spring mattress with pocketed coils can also offer targeted back support, especially for heavier sleepers who need firmer pushback.

Are spring mattresses good for side sleepers? +

While some side sleepers may find spring mattresses comfortable, they often prefer memory foam for better cushioning at the hips and shoulders. A spring mattress may create pressure points at these areas due to its firmer, less contouring surface.

Do memory foam mattresses sleep hot? +

Traditional memory foam mattresses may retain heat; however, modern versions feature cooling technologies like gel infusions or open-cell designs to enhance airflow. Flo's foam mattress includes a plush cover with 3D Air-Flo™ technology that helps you sleep up to 5°C cooler.

How do I choose between a spring and a memory foam mattress? +

Choose based on your personal comfort needs and sleeping position. If you prefer firmness, responsiveness, and cooler sleep, opt for a spring mattress. For personalised contouring, minimal motion transfer, and superior pressure relief, memory foam is ideal.

Which mattress is better for health — foam or spring? +

For health and long-term comfort, foam mattresses are usually the better option because they support the spine evenly and reduce pressure on joints. Spring mattresses can be suitable for those who prefer a firmer feel, but they may transfer motion and offer less pressure relief overall.
