How to Read a Furniture Spec Sheet

Most people buying furniture in Singapore focus on photographs — the way a sofa looks styled against white walls, or how a dining table appears in a sun-drenched showroom. That is understandable. But the photograph tells you almost nothing about whether the piece will last five years or fifteen, fit comfortably through your HDB corridor, or hold up under the weight of a full Sunday family gathering. The spec sheet tells you all of that — if you know how to read it.

After decades of helping Singapore homeowners furnish HDB flats, condos, and landed homes, our team has watched good buyers make avoidable mistakes by skipping over specifications they did not understand. This guide walks through every major element you will encounter on a furniture spec sheet, what each number or term actually means, and which details deserve the most scrutiny.

Why dimensions deserve more attention than most buyers give them

The first section on any spec sheet is almost always the dimensions: overall width, depth, height, and sometimes seat height or seat depth. These numbers matter more in Singapore than almost anywhere else, for one simple reason — our homes are precisely sized.

A 4-room HDB living room is typically around 20-22 square metres. A 3-room flat might allocate as little as 15 square metres to the combined living and dining area. When a sofa is listed at 280cm wide and your living room wall runs 300cm, that leaves 20cm of clearance — fine until you factor in a side table or a passage route. Seat depth is equally important: a sofa with 95cm of seat depth in a room that is only 3.5 metres from the TV wall will dominate the space.

Check the outer dimensions, not just the product category

For bed frames, always check the outer frame dimensions against your bedroom floor plan, not just the mattress size. A Queen bed frame listed as “fits 152cm Queen mattress” might have an outer width of 168cm or 172cm once the frame is included. Add bedside tables on both sides and that figure climbs further. Our bed frame collection includes full external dimensions on every product page specifically for this reason.

For dining tables, note whether the listed dimension is with or without an extension leaf. A 160cm extendable table that extends to 220cm changes your entertaining capacity entirely — but the 220cm figure needs to clear comfortably in your dining area with chairs pulled out.

The practical rule: measure your room, then subtract a minimum of 90cm for any primary circulation route before you allocate furniture.

What frame materials and construction terms actually mean

Once you move past dimensions, most spec sheets describe the frame material — and this is where the language gets vague quickly. Terms like “solid wood,” “engineered wood,” and “MDF” appear without context, and without context they are almost meaningless.

Solid wood

Solid wood frames vary enormously by species. Rubberwood is a dense, affordable tropical hardwood that performs well in Singapore’s humidity. Acacia is harder and more characterful, but can show movement in very humid conditions. Teak and mahogany are genuinely durable hardwoods that resist moisture well — you will see these in higher-specification pieces. “Mixed hardwood” is a term that covers almost anything and tells you very little.

Engineered wood

Engineered wood is not inherently inferior — high-density particleboard or MDF with proper veneer and edge-banding performs well in stable indoor environments. The concern in Singapore is humidity exposure. Engineered wood used in shoe cabinets near the entrance or in bathrooms can delaminate over time if moisture gets in through unsealed edges. Check whether the spec sheet mentions edge-banding and surface treatment.

Sofa frames and load ratings

For sofas, look for the frame material specified separately from the cushion fill. A “hardwood frame” without specifying kiln-dried — a process that removes moisture from timber before use, reducing the risk of warping — is a weaker claim than it sounds in a humid climate like Singapore’s. Our sofa collection specifies frame construction and cushion density across every listing, because those two details determine how the sofa performs after the first few years of daily use.

Load ratings appear on some spec sheets, particularly for dining chairs, bar stools, and office chairs. A standard load rating of 100-120kg is acceptable for most residential use. If you have larger family members or anticipate heavy daily use, look for 130-150kg ratings in the specification.

How to decode upholstery and surface finish codes

Upholstery and surface materials get their own section on most spec sheets, and they often use shorthand that rewards translation.

PU leather

PU leather, or polyurethane leather, is a synthetic material that replicates the look of leather at a lower cost. It is easier to clean than fabric and reasonably moisture-resistant, but has a shorter lifespan than genuine leather — typically 3-7 years with daily household use before the surface begins to peel or crack, depending on quality grade. Some spec sheets list the PU thickness in millimetres; thicker PU generally lasts longer.

Genuine leather grades

Full-grain leather and top-grain leather are genuine leather grades. Full-grain retains the natural surface of the hide and is the most durable — it develops a patina over time rather than deteriorating. Top-grain leather has been lightly sanded or buffed for a more uniform surface, making it slightly less durable than full-grain but still a significant step above PU.

If a spec sheet simply says “genuine leather” without specifying the grade, ask which part of the hide is used — split leather, from the lower layers, behaves closer to PU than to top-grain.

Hard surface materials

For hard surfaces — dining tables, coffee tables, TV consoles — look for these terms:

• Sintered stone: a compressed, kiln-fired surface engineered from natural minerals. Highly scratch-resistant and heat-resistant, which makes it well-suited to dining tables in active households.
• Tempered glass: heat-treated for strength. A 10mm tempered glass top is substantially stronger than a 6mm equivalent. Thickness matters.
• Solid surface: a polymer-composite material often used in built-in applications. Seamless and repairable.
• Lacquer finish: a sprayed coat applied over MDF or engineered wood. Durable when applied thickly, but chips at edges over time. Check whether the spec mentions the number of lacquer coats.

Browse our dining table collection if you want to compare sintered stone, tempered glass, and solid wood surfaces side by side — the spec pages include surface-specific care notes.

What the numbers on a mattress spec sheet tell you

Mattress spec sheets carry the most information of any furniture category, and they are worth reading carefully given that you will spend roughly a third of your life on the product.

Spring count

Spring count is the most commonly cited figure — a Queen mattress, 152cm x 190cm in Singapore sizing, typically carries between 1,000 and 2,500 individually pocketed coils, depending on the coil diameter and configuration. A higher coil count generally delivers more precise motion isolation and pressure distribution, but only if the coils are individually pocketed. Continuous-coil or Bonnell spring systems with a high coil count do not behave the same way as pocketed spring systems.

Foam density

Foam density is listed in kg/m³. For comfort layers, 28-35 kg/m³ is a standard range. For support or base foam, 35-45 kg/m³ is the typical residential range — higher density means the foam holds its shape longer before compressing permanently. Memory foam is often listed by density; 50-80 kg/m³ is considered high-density for memory foam.

ILD rating

ILD rating, or Indentation Load Deflection, describes firmness. Lower ILD means softer; higher ILD means firmer. A medium mattress might carry an ILD of 20-30, while a firm mattress sits at 30-40. This number is useful when comparing mattresses across brands, though manufacturers measure ILD in slightly different ways.

Cover materials

Cover materials are increasingly specified on premium mattresses — Tencel, bamboo-derived fabric, and ice-silk are all moisture-wicking options suited to Singapore’s climate. A ticking, or mattress cover, listed as “polyester jacquard” without any moisture-management claim will sleep noticeably warmer. Browse our mattress collection to compare cover specifications and spring configurations across the range.

Reading a spec sheet at the showroom versus online

There is one limitation to reading spec sheets in isolation: they describe a product accurately, but they cannot tell you how it feels under your particular body weight, your preferred sleep position, or your sitting habits. Two sofas with identical foam density specifications will feel different if one uses a serpentine spring base and the other uses a webbing base beneath the cushions — the spec sheet will not always flag this distinction.

Our recommendation, which holds across over 100 years of combined industry experience in our management team, is to use the spec sheet to filter: rule out pieces that are too deep, too heavy, or use materials unsuitable for Singapore’s humidity. Then visit the showroom to make the final call based on direct experience.

Our 5 Ubi Link showroom keeps a broad range of configurations on the floor daily, from 11:30 AM to 9 PM — bring your floor plan dimensions and your list of specification questions. The difference between two pieces of comparable specification often comes down to details that only become apparent when you sit in them.

Using specifications to compare value across price points

The final skill in reading a spec sheet is using it as a comparison tool rather than just a description. When two sofas are priced differently, the spec sheet tells you exactly where the difference lies: frame material, cushion foam density, spring system, upholstery grade, or all of the above.

A sofa with a rubberwood frame, 32kg/m³ HR foam cushions, and webbing seat support is honestly specified at a mid-range price. A sofa with a kiln-dried hardwood frame, 45kg/m³ high-resilience foam cushions, and serpentine spring seating support justifies a higher price — and the spec sheet makes that case clearly if you know what to read.

The same logic applies across every furniture category. Specifications are not marketing language — they are the product’s actual anatomy, written down. Once you know how to read them, you are making a genuinely informed decision rather than a visually guided guess. That knowledge tends to produce furniture purchases you are still satisfied with a decade later, which is, in our experience, the only kind worth making.
