To compare two mattresses by specification, line up five numbers side by side: foam density, spring count if applicable, mattress height, firmness rating, and material composition.

Those five figures tell you more about long-term performance than any brand description will.

The sections below walk through each in turn, explain what the numbers mean in practice, and name the mistakes that catch most first-home buyers off guard.

What to Know Before You Start

Most mattress comparisons begin in the wrong place.

Buyers read brand names, study lifestyle photography, and compare prices, while the construction figures sit quietly in the small print.

The small print is where the decision actually lives.

Two mattresses can carry identical price tags and feel completely different after six months of nightly use, because their internal materials are built to different standards.

Foam degrades at different rates depending on density.

Springs transfer movement differently depending on how they are engineered.

Height and firmness determine how the mattress performs for your body weight and sleeping posture.

None of that is visible from a photograph.

Before comparing any two mattresses, you need three things: the full specification sheet for each mattress, your bed frame dimensions confirmed, and a clear picture of who will sleep on the mattress and in what posture.

A 65 kg side sleeper and a 90 kg back sleeper have different needs from the same mattress, and the specifications that serve one well may not serve the other at all.

Esteller carries mattresses from Dr. Maxis and Somnuz across a range of constructions and price points.

The full mattress range lists specifications transparently, so the comparison can be made on substance.

Step 1: Read the Foam Density, Not the Comfort Description

Foam density is measured in kilograms per cubic metre, and it is the single most reliable predictor of how long a mattress holds its support.

High-resilience foam at 35 kg/m³ or above keeps its shape and firmness for years of daily use.

Foam below 25 kg/m³, which appears in a significant portion of mass-market mattresses, softens and loses its support profile within a few seasons.

The difficulty is that foam density is almost never the headline figure.

Retailers lead with comfort language: “plush”, “cloud-like”, “hotel-grade”.

These descriptions are not wrong, necessarily, but they describe the surface feel on the day of purchase.

Density determines the feel in year three.

Ask for the number.

If a retailer cannot provide it, that tells you something.

When comparing two mattresses, place their foam densities side by side.

A mattress with memory foam at 50 kg/m³ over a base foam at 35 kg/m³ is a materially different construction from one with comfort foam at 20 kg/m³ over a base at 18 kg/m³, regardless of how both are described in the product name.

Step 2: Understand the Spring Construction

Not every mattress uses springs, but where springs are present, the type of spring construction matters considerably.

The two most common types in Singapore are Bonnell springs and pocketed springs, and they behave very differently in use.

Bonnell springs are linked together in a continuous unit.

When one spring compresses, the springs around it respond, which means movement travels across the mattress surface.

For a single sleeper, this is rarely a problem.

For couples, it means that one partner rising at 5am is likely to disturb the other.

Esteller’s Bonnell spring mattress collection is well suited to single beds, guest rooms, and households where motion transfer is not a priority.

Pocketed springs work differently.

Each coil is enclosed in its own fabric sleeve and moves independently.

The mattress can yield to a shoulder in one place and a hip in another without passing the compression across to the other side.

That independence is the practical logic of the design.

For couples sharing a bed, pocketed springs are the considered choice.

The pocketed spring mattress collection is where to begin that comparison.

When comparing two mattresses, note whether one uses pocketed springs and the other uses Bonnell, or whether one is foam-only.

These are not just engineering differences. They determine how the mattress performs for your household’s actual sleeping pattern.

Step 3: Check the Height

Mattress height affects three things that buyers often underestimate: the feel of the mattress under body weight, the overall bed height once placed on a frame, and the durability of the construction.

A taller mattress generally accommodates more material layers, which means more opportunity to engineer distinct support and comfort zones.

A mattress at 25 cm to 30 cm typically carries more layering than one at 15 cm to 18 cm, though height alone is not a guarantee of quality.

The bed height question matters particularly in Singapore homes where storage drawers are built into the base.

Confirm that your frame’s clearance accommodates the mattress height you are considering, and check the final bed height against the room’s proportions.

A bed that sits too high relative to ceiling height or furniture scale reads as misjudged in the room, regardless of how well the mattress performs.

For households fitting out a first home with a queen mattress or super single, this is the step most often skipped.

Measure the frame, confirm the height, then shortlist.

Step 4: Place Firmness on the Right Scale

Firmness is the most personal variable in a mattress comparison, and also the most commonly misread.

The intuition that a firmer mattress is better for your back is only partially correct.

A mattress that is too firm for your body weight and sleeping posture creates pressure points at the hips and shoulders, particularly for side sleepers.

A mattress that is too soft fails to keep the spine in a neutral alignment for back and stomach sleepers.

Body weight is the calibrating factor.

As a working guide, lighter sleepers under 65 kg typically find medium to medium-soft constructions more easeful.

Sleepers between 65 kg and 90 kg generally perform well on medium-firm.

Heavier sleepers above 90 kg, or those who sleep predominantly on their back, benefit from firmer support.

These are starting points, not prescriptions.

Esteller’s mattress range is organised by firmness so the comparison is straightforward.

The shop by firmness page lists options from very soft through medium firm to very hard, so you can narrow the shortlist before comparing constructions.

The well-made approach is to settle the firmness range first, then compare specifications within it.

Step 5: Read the Material Composition in Full

Most mattresses combine multiple material layers, and the order and thickness of those layers is as important as the materials themselves.

A memory foam layer at the surface responds to body heat and moulds to your posture.

Its thickness determines how pronounced that effect is.

A latex layer provides a more responsive, springier feel than memory foam and holds up particularly well in Singapore’s humidity, because natural latex resists moisture and dust mites by composition rather than by treatment.

When comparing two mattresses, list the materials in order from surface to base for each, note the thickness of each layer, and note the density where it is given.

A mattress described as “memory foam” may carry 2 cm of memory foam over a base that is primarily low-density polyurethane.

That is a very different construction from one with 5 cm of high-density memory foam over a 35 kg/m³ support core.

The description is the same. The performance is not.

Latex mattresses deserve a specific note.

Natural latex performs differently from synthetic or blended latex, and the composition should be stated clearly in the specification.

Esteller’s latex mattress collection lists material composition in full.

Step 6: Build the Comparison Table

Once you have gathered the full specifications for both mattresses, place them in a table.

Side by side, the differences become clear in a way they do not when read separately.

A table like this makes it much harder to let marketing language carry the decision.

The foam density figure either competes or it does not.

The spring construction is either appropriate for how the bed will be shared or it is not.

The numbers resolve the comparison where descriptions leave it open.

Common Mistakes When Comparing Mattresses

Comparing Price Without Comparing Construction

A lower price on one mattress and a higher price on another tells you very little until the construction figures sit beside each other.

A mattress at SGD 800 with 35 kg/m³ foam and pocketed springs is a premium specification at that price point.

A mattress at SGD 1,500 with 20 kg/m³ foam over a Bonnell spring unit is not, regardless of the price.

Trusting Firmness by Name Alone

There is no industry-standard scale for mattress firmness.

One brand’s “medium firm” may sit closer to another brand’s “firm”.

The only reliable test is to lie on the mattress for at least ten minutes in your usual sleeping posture.

An online description of firmness is a starting filter, not a final answer.

The firmness label is the beginning of the research, not the end of it.

Overlooking the Base Foam

Most buyers focus on the comfort layer at the surface.

The base foam is what determines long-term structural support.

A high-density comfort layer over a low-density support core will compress unevenly within a year or two, as the base softens faster than the surface.

Ask for the base foam density as well as the comfort layer density.

Ignoring How Singapore’s Climate Affects Material Choice

Memory foam retains body heat.

In a Singapore bedroom without air conditioning running through the night, a thick memory foam layer can make the sleeping surface noticeably warm by early morning.

Latex and pocketed spring constructions with breathable covers allow more airflow and perform more comfortably year-round in a tropical climate.

If you sleep warm, note the cover fabric and the ventilation design of each mattress, not just the core construction.

Comparing Mattresses Without Confirming the Frame

A mattress performs differently on a slatted frame, a solid base, and a storage bed frame.

Slats that are more than 7 cm apart allow the mattress to sag between them over time, regardless of foam quality.

Confirm your frame’s slat spacing or base type before deciding whether the mattress specification is appropriate for it.

The beds by type collection is useful here if a new frame is also part of the decision.

When to Visit the Showroom

Specification comparison gets you to the right shortlist.

The showroom is where the shortlist resolves.

On a Tuesday evening, around 7pm when the room is quiet, lying on a mattress for ten minutes in your usual sleeping position tells you something no specification sheet can: how the firmness registers against your actual body weight, how the surface feels against skin temperature, and whether the edge support holds when you sit to one side.

This often happens with first-home buyers in particular: the mattress that read as the clear winner on paper sometimes loses the comparison the moment it is tested, and the one that looked like a compromise turns out to be the considered choice.

If the two mattresses on your shortlist are in different firmness categories, lying on both back to back in the showroom resolves the comparison in fifteen minutes.

Bring the specification table you have built.

The team can explain where any figures are missing from the sheet and walk through how each construction will perform for your frame and sleeping pattern.

The Esteller showroom is at 604 Sembawang Road, #01-18 Sembawang Shopping Centre, and is open daily from 10am to 10pm.

Frequently Asked Questions

What Foam Density Should I Look for in a Mattress?

High-resilience foam at 35 kg/m³ or above is the threshold that holds its support reliably over years of daily use.

Below 25 kg/m³, most foams soften noticeably within 18 to 24 months.

For a mattress in daily use over five or more years, 35 kg/m³ is the baseline specification to compare against.

Some mattresses use different foam densities for the comfort layer and the support core, so ask for both figures.

Does a Higher Spring Count Mean a Better Mattress?

Spring count is one factor, not the only one.

A higher pocketed spring count generally means finer contouring and better motion isolation, because the individual coils are smaller and more numerous.

However, a pocketed spring unit with 800 well-engineered coils may outperform a Bonnell unit with 1,000 coils for a couple sharing a bed, because the construction type matters as much as the count.

Compare spring type first, then spring count within the same type.

How Do I Compare Mattresses for a Couple With Different Sleep Preferences?

Where two sleepers have clearly different firmness preferences, a pocketed spring construction is the better starting point.

The independent coil action allows each side to respond differently to body weight without transferring that response across the bed.

For firmness, look for a medium-firm specification, which holds the widest range of sleepers without over-compromising for either.

If the gap in preference is significant, a dual-zone or adjustable construction may be the honest answer.

The adjustable bed collection is worth considering in that case.

Is Latex Better Than Memory Foam for Singapore’s Climate?

For most Singapore sleepers, natural latex performs more comfortably year-round.

It is inherently breathable, responds quickly to movement rather than holding a body impression the way memory foam does, and resists dust mites and moisture by its own composition.

Memory foam’s contouring is valuable for pressure relief, but its heat retention can work against it in a tropical bedroom.

If temperature is a concern, a latex construction or a hybrid with a ventilated foam layer is the more considered choice.

What Size Mattress Fits a Standard Singapore HDB Bedroom?

A standard HDB master bedroom accommodates a king or queen mattress comfortably, provided the room layout allows for bedside clearance on both sides.

The king mattress at 183 cm x 190 cm suits larger master bedrooms.

The queen mattress at 152 cm x 190 cm is the more common fit.

Secondary bedrooms more typically suit a super single or single.

Measure the room with the floor plan in hand before shortlisting a size, accounting for wardrobe doors, the door swing, and the path around the bed.

The Decision That Repays the Time Spent on It

A mattress bought without reading the construction figures is a decision made largely on faith.

The foam density, the spring construction, and the material layering are the figures that determine how the mattress performs for the people sleeping on it, not in the first week but in the third year.

The comparison table takes twenty minutes to build.

That twenty minutes is worth more than any amount of reading comfort descriptions, because it places the actual specifications beside one another and lets the numbers do the work.

Esteller’s affordable luxury mattress range, from approximately SGD 600 to SGD 2,500, carries transparent material specifications so that comparison can be made honestly.

Every piece is backed by a three-year warranty, and free delivery applies on orders above SGD 500.

The 4.8 rating across 96 Google reviews reflects how these specifications hold up over actual daily use, not just at the point of purchase.

Explore the full mattress collection to begin shortlisting by construction, or browse the beds by type collection if the frame decision is running in parallel.

New designs are added through the year, so a return visit is rarely wasted.

When the shortlist is settled, the showroom at 604 Sembawang Road, #01-18 Sembawang Shopping Centre is open daily from 10am to 10pm.

Bring the specification table.

The comparison that looked close on paper often resolves itself quickly once the mattress holds the weight of the person who will sleep on it.
