Furniture Shopping Glossary: Common Terms Explained

Walk into a furniture showroom for the first time and you will likely encounter a small vocabulary lesson you did not sign up for. Kiln-dried hardwood. Pocketed spring. Sintered stone. High-density foam. Top-grain leather. These terms get used casually by salespeople and appear prominently on product labels — but if nobody has explained what they actually mean, they can feel more like a performance of quality than a useful description.

This guide is our attempt to change that. Over 100 years of combined industry expertise across the MaxiHome management team means we have had this glossary conversation thousands of times in our showroom, with first-time BTO owners, upsizing families, and everyone in between. The terms below are the ones that come up most frequently, grouped by category so you can find what you need quickly.

Our goal is simple: when you are ready to buy, you should be able to read a product specification and understand exactly what you are getting.

Frame and structural terms

Hardwood vs softwood

Wood is broadly categorised into hardwoods, from deciduous trees like oak, ash, and rubberwood, and softwoods, from coniferous trees like pine.

For furniture frames, hardwood is generally preferred because it is denser, more resistant to denting, and holds joinery — screws, dowels, and mortise-and-tenon joints — far more reliably over time.

Softwood furniture is not automatically poor quality, but it is more common at the budget end of the market and less suited to structural components like sofa frames and bed bases.

Kiln-dried timber

Before hardwood is cut and assembled into furniture, responsible manufacturers dry it in a controlled kiln environment to reduce its moisture content to roughly 6–8%.

Timber that has not been properly kiln-dried retains more moisture and will warp, crack, or twist as it adjusts to the humidity of your home — particularly relevant in Singapore, where indoor humidity typically ranges between 70% and 90% year-round.

When a product listing says “kiln-dried hardwood frame”, it is telling you the timber has been stabilised before construction, which meaningfully reduces the risk of frame movement after installation.

Engineered wood: MDF, plywood, and particleboard

These three materials are frequently confused with one another.

MDF, or Medium Density Fibreboard, is made from wood fibres bonded under high pressure, producing a smooth, dense board that takes paint and veneer well but is heavy and does not respond well to moisture exposure.

Plywood is made from layered wood veneers with alternating grain directions, which gives it structural strength and flexibility — it is better suited to structural applications like wardrobe carcasses and drawer bases.

Particleboard, also called chipboard, is the lightest and least expensive of the three, made from compressed wood chips and adhesive. It is widely used in flat-pack furniture but is the most susceptible to moisture damage and sagging under load.

Quality varies significantly within each category — thickness, adhesive quality, and surface treatment all matter.

Joinery methods

How furniture components are connected determines how long the piece holds together.

Mortise-and-tenon joints, where a protruding tongue fits into a corresponding cavity, are among the strongest traditional woodworking joints.

Dowel joints use cylindrical wooden pins to align and connect panels.

Corner blocks — small triangular wooden reinforcements glued and screwed into frame corners — are a good indicator of quality in sofa frames.

Metal cam locks and plastic connectors are common in flat-pack furniture. They work, but they do not have the longevity of solid wood joinery under regular stress.

Upholstery and fabric terms

Top-grain leather vs full-grain leather vs bonded leather

Full-grain leather retains the complete outer surface of the hide, including natural markings and variations — it is the most durable and develops a patina over years of use.

Top-grain leather has had the outermost layer sanded and treated to produce a more uniform surface. It is softer to the touch but slightly less durable than full-grain.

Bonded leather, also called reconstituted leather, is an entirely different product. It is made by bonding shredded leather fibres and polyurethane onto a backing material. It looks like leather at first glance and costs significantly less, but it will begin to peel or flake within a few years under regular use — particularly in Singapore’s heat and humidity.

Always confirm which type you are buying before committing to a leather sofa.

Performance fabric

This is a broad term for upholstery fabrics engineered to resist staining, fading, and moisture.

Common performance fabric technologies include solution-dyeing, where colour is added to the fibre before weaving rather than applied to the surface, tightly woven microfibre constructions, and proprietary treatments.

A genuine performance fabric should specify what it resists. Look for “stain-resistant”, “pet-friendly”, or “moisture-resistant” with a tested standard, rather than the label alone.

Foam density and ILD rating

Sofa and mattress cushioning is typically characterised by two separate measurements.

Density, expressed in kg/m³, indicates the weight of foam per cubic metre — it is a durability indicator. Foam at 30 kg/m³ or below will compress and lose shape faster than foam at 40–45 kg/m³.

ILD, or Indentation Load Deflection, measures firmness — how much force is needed to compress the foam by a defined amount.

A sofa cushion with high density and moderate ILD will hold its shape over years of daily use. Low-density foam is the most common source of sagging sofas two or three years after purchase.

When browsing our sofa collection, we are happy to confirm the foam specification for any model in the showroom.

Duck feather and down fill

Some cushion constructions use duck feather or down as a filling component, either alone or wrapped around a foam core.

Pure feather fill gives a very soft, sink-in feel but requires regular refluffing and loses shape quickly.

A feather-wrap-over-foam construction — where a foam core is surrounded by a feather-and-down layer — offers a good balance of structure and softness, without the maintenance demands of a pure feather cushion.

Mattress construction terms

Pocketed spring, or individually pocketed coil

In a pocketed spring mattress, each coil is individually wrapped in fabric, meaning coils move independently of one another.

This independent movement means the mattress can contour to different body shapes, reduces motion transfer between sleep partners, and delivers targeted support to the shoulder, hip, and lumbar regions — the three primary pressure points for most sleepers.

Queen-size mattresses typically contain between 1,500 and 2,500 pocketed coils depending on the tier. A higher coil count is generally, though not always, associated with finer contouring.

Our mattress collection carries models across a range of coil configurations — the specification pages list coil counts where available.

Bonnell spring and continuous coil

Bonnell springs are the traditional hourglass-shaped coils interconnected by a wire frame.

They are durable and provide a firm, bouncy feel, but because the coils are connected, motion transfers more readily across the mattress surface.

Continuous coil systems work similarly — a single wire is formed into multiple rows of coils — and share the same motion-transfer characteristic.

Both are common in entry-level mattresses. Neither is poor quality by definition, but they suit different sleepers than pocketed spring systems.

Memory foam

Memory foam, or viscoelastic foam, is temperature-sensitive. It softens in response to body heat and conforms closely to the body’s contours.

This close conforming reduces pressure points for many sleepers but can create a “stuck” sensation that some people find uncomfortable.

Memory foam also retains heat, which is a significant consideration in Singapore’s climate. Better memory foam constructions incorporate open-cell or gel-infused formulations to address heat retention, though no memory foam performs as coolly as a well-ventilated spring system.

Natural latex

Latex sourced from rubber trees, known as natural latex rather than synthetic or blended latex, is valued for its responsiveness, durability, and natural breathability.

It springs back quickly when compressed, unlike memory foam, and resists mould and dust mites — relevant advantages in Singapore’s humidity.

Natural latex carries a price premium over synthetic alternatives, so it is worth confirming the latex type in any product specification.

Euro top vs pillow top

Both terms describe an extra comfort layer built into the top of the mattress, but they are constructed differently.

A pillow top is a separate cushioning layer stitched onto the mattress surface, leaving a visible gap between the top and the border.

A Euro top is integrated flush with the mattress border for a cleaner, more uniform profile.

Functionally, both add cushioning to the sleep surface — the difference is primarily structural and aesthetic.

Surface materials for tables and cabinetry

Sintered stone

Sintered stone is manufactured by subjecting natural minerals to extreme heat and pressure — a process that replicates, in compressed time, the geological forces that form natural stone.

The result is a non-porous, scratch-resistant, heat-resistant surface that does not require sealing. It has become increasingly common for dining tables and TV consoles in Singapore homes.

The non-porous surface means it does not harbour bacteria and is easy to clean.

It is worth noting that sintered stone, despite its hardness, is brittle under impact loading — a sharp heavy blow to a thin edge can chip it.

Solid wood veneer vs solid wood

A solid wood veneer is a thin slice of real wood bonded onto an engineered wood substrate, usually plywood or MDF. It gives the piece the visual character and warmth of natural wood at a lower cost and, often, with greater dimensional stability than solid wood in humid environments.

Solid wood is exactly what it sounds like — the structural component is a continuous piece of timber.

For most furniture applications in Singapore, a quality veneer on a plywood substrate performs as well as, or better than, solid wood because it is less susceptible to humidity-driven warping.

Lacquered finish

A lacquered surface has been treated with a clear or pigmented liquid coating that dries to a hard, smooth film.

Lacquering provides protection against moisture and staining, and produces either a gloss, semi-gloss, or matte finish depending on the formulation.

High-quality lacquer on well-prepared surfaces is durable. Low-quality or thinly applied lacquer will chip or peel at edges over time.

Structural terms for storage and beds

Full extension vs soft-close drawer runners

Full extension runners allow a drawer to open completely to its full depth, giving you access to the entire interior.

Soft-close runners incorporate a damped mechanism that slows and silences the drawer as it closes — preventing it from slamming.

A well-specified wardrobe or kitchen cabinet will have both.

When evaluating storage furniture, ask whether the runners are full extension, and whether soft-close is standard or an upgrade.

Our wardrobe collection and bed frame collection include specification details for drawer and storage components.

Storage bed / hydraulic lift base

A storage bed, sometimes called an ottoman bed, uses a gas-hydraulic piston system to allow the bed base to be lifted for under-bed storage access.

In a well-engineered system, the lift mechanism is calibrated to the weight of the mattress — so it opens smoothly and holds its position safely.

Entry-level hydraulic systems can lose tension over time. Better-quality systems use heavier-gauge pistons and will carry a clear operational warranty.

Slat bed base

A slatted bed base uses a series of horizontal timber slats across the bed frame to support the mattress.

Slat spacing matters: slats spaced more than 7–8 cm apart may allow a mattress to sag between them over time, particularly with memory foam or latex constructions that are not self-supporting.

Curved or sprung slats — which flex slightly under load — provide a degree of additional cushioning and are generally preferable to flat rigid slats.

How to use this glossary when you shop

Reading product listings is one thing; the real test is handling furniture in person. Foam density and leather grade are hard to assess from a photograph — they become apparent when you sit on a sofa, press a cushion, or run your hand across a surface.

The terms above give you the right questions to ask, but the answers are best confirmed physically.

If you are in the middle of furnishing a new home or replacing pieces that have served their time, our showroom at 5 Ubi Link is set up for exactly this kind of comparison.

Multiple sofa configurations, mattress constructions, and surface materials are on the floor together, labelled with specifications — so you can test what different foam densities feel like side by side, compare leather grades in natural light, and ask our team about any specification that is not immediately clear.

We are open daily from 11:30 AM to 9 PM, including weekends and public holidays. Bring your floor plan if you have one; bring questions if you have those. No purchase pressure, no time limit.

Rated 4.8 across 2,733+ verified Google reviews, our team’s most common feedback relates to the showroom experience — specifically, that homeowners leave with clearer decisions than they arrived with. That is the intention.

Furniture is a considered purchase, and it should feel like one.

A note on what these terms do not tell you

Specifications describe construction. They do not always capture finish quality, the care taken in assembly, or the difference between a factory that tolerates variance and one that does not.

In our experience, two mattresses with identical coil counts can perform differently depending on spring temper, foam quality, and cover construction.

Two wardrobes with the same drawer runner specification can feel very different depending on panel thickness and fitting precision.

This is why we recommend using the glossary as a starting point rather than a final filter. Know what the terms mean, ask for the specifications, and then — where it matters — feel the difference in person.

That combination of informed vocabulary and direct experience will serve you better than either one alone.
