Still on the Fence About Spring Mattresses? Here's What You Need to Know.
Spring mattresses have been around for over a century — and they're still the most popular mattress type in Singapore for a reason. But not all spring mattresses are created equal. The difference between a basic bonnell spring and a quality individually pocketed spring can mean the difference between waking up refreshed and waking up with a sore back.
If you're shopping for a spring mattress in Singapore and feeling overwhelmed by the options, this guide is for you. We'll walk you through exactly how spring mattresses work, which type suits your needs, and what to look for before you buy.
How Do Spring Mattresses Work?
At their core, spring mattresses use a system of metal coils to provide support. When you lie down, the coils compress under your weight and push back, keeping your body elevated and your spine aligned. The key variables are the type of coil system used, the coil count, and the comfort layers sitting above the springs.
These variables determine everything — from how well the mattress isolates motion to how cool it sleeps to how long it lasts.
The Main Types of Spring Mattresses
Bonnell Spring (Open Coil)
The oldest and most basic spring system. Bonnell coils are hourglass-shaped and connected to each other in a grid. When one coil moves, neighbouring coils move with it — which means poor motion isolation and uneven support. You'll typically find this system in very budget mattresses.
For a primary mattress you sleep on every night, bonnell spring is generally not recommended. The motion transfer alone makes it a poor choice for couples.
Pocketed Spring (Individually Wrapped Coils)
This is where modern spring technology really shines. In a pocketed spring mattress, each coil is individually wrapped in its own fabric pocket. This means every coil responds independently to pressure — giving you precise, zoned support and dramatically reduced motion transfer.
When your partner rolls over at 3 AM, you won't feel a thing. When your shoulder presses into the mattress, only the coils directly beneath it compress — not the ones under your hips. This targeted response is what makes pocketed spring the gold standard for spring mattresses today.
Continuous Coil
A single wire is fashioned into rows of coils throughout the mattress. More durable than bonnell spring, but still lacks the motion isolation and individualised support of pocketed coils. Found in mid-range budget mattresses.
Why Pocketed Spring Is the Right Choice for Singapore
Beyond superior support, pocketed spring mattresses have a specific advantage that matters deeply in Singapore — airflow.
Because the coils are individual and the mattress has open space within its spring layer, air circulates freely through the mattress as you sleep. This passive ventilation keeps the sleep surface cooler and reduces moisture build-up — a genuine quality-of-life improvement in our year-round humidity and heat.
Compare this to a pure foam mattress, which has no airflow within its core and can trap body heat throughout the night. For Singaporeans who run warm or sleep without heavy aircon, a pocketed spring mattress is often the more comfortable long-term choice.
What to Look for When Buying a Spring Mattress in Singapore
Coil Count
More coils generally means more precise support and better contouring. A queen-size mattress with 800–1,000+ individually pocketed coils will outperform one with 400 coils in terms of support distribution and durability. That said, coil count alone isn't everything — coil gauge (thickness) and the quality of the comfort layers above matter just as much.
Comfort Layers
Most quality spring mattresses in Singapore aren't just springs — they combine a pocketed spring base with comfort layers on top. Common comfort layer materials include:
Memory foam — Adds pressure relief and body contouring above the spring base. Great for side sleepers or those with joint pain. Explore memory foam options if this appeals to you.
Latex — Naturally breathable and responsive, latex comfort layers add a slightly bouncier feel while enhancing the cooling properties of the mattress. Check out latex mattresses for pure latex options or hybrids.
Foam — Standard polyfoam or high-density foam layers add cushioning and help shape the overall firmness profile of the mattress.
Cover Material
In Singapore's climate, the cover fabric matters more than people realise. Look for breathable materials like bamboo fabric, Tencel, or moisture-wicking blends. Water-repellent covers (like Teflon-treated fabric) are worth considering for households with young children or anyone prone to night sweats.
Height (Mattress Thickness)
Spring mattresses in Singapore typically range from 8 to 14 inches. Thicker mattresses tend to offer more comfort layers and a more luxurious feel, but they also sit higher off the base — worth factoring in if you have a low bed frame or platform bed.
Spring Mattress Sizes: Picking the Right Fit for Your HDB or Condo
Single (91 x 190 cm) — Children's rooms, helper's quarters, or compact spare bedrooms.
Super Single (107 x 190 cm) — Popular for single adults who want extra width in a standard HDB room.
Queen (152 x 190 cm) — The most common choice for Singapore master bedrooms. Fits comfortably in most HDB layouts.
King (183 x 190 cm) — Ideal for larger condo or landed master bedrooms. Measure your room carefully before buying.
How Long Does a Spring Mattress Last?
A quality pocketed spring mattress, properly maintained, should last 8–12 years. Signs it's time to replace yours include visible sagging or body impressions, increased back or joint discomfort upon waking, audible squeaking or creaking from the springs, and consistently better sleep quality when away from home.
Rotating your mattress every 3–6 months and using a mattress protector will extend its lifespan significantly.
