Custom Seat Cushions: What Goes Into Getting One Right

Custom Seat Cushions: What Goes Into Getting One Right

A seat cushion fitted for your bay window or built in carpentry nook looks like a simple feature to add to your space. But getting one right depends on far more than picking a fabric and foam thickness.

This guide covers what to consider before ordering a custom bay window or built-in carpentry seat cushion: measuring, climate, fabric, cost expectations, and a real project example with exact numbers.


Off-the-shelf vs. custom-measured: what's the actual difference?

Searching for "bay window cushion Singapore" mostly surfaces two very different products:

Off-the-shelf / budget custom Site-measured custom
How it's measured Customer self-measures and submits dimensions online Measured in person, on site, by the maker
Handles irregular shapes Usually assumes a straight rectangle Accounts for depth variation, and non-standard corners
Typical price range From around $88, priced largely by foam density and size 2.4m starts from $690, price varies by size, complexity and upholstery type
Turnaround Often fast, sometimes stocked in standard sizes 4 - 6 weeks
What happens if it doesn't fit Usually the customer's responsibility to return, resize, or accept it Maker takes responsibility for correcting the fit

Both have a place.
A budget option can work fine for a genuinely simple, rectangular bay window. The risk is applying that same approach to a window that isn't actually simple, which is more common than people expect.


Why bay window seats are harder to measure than they look

At first glance, most bay windows look regular but there's often

  • A slight variation in depth across the length of the seat
  • An off notch or irregular corner
  • A corner that isn't quite the 90 degree angle it appears to be
  • Ergonomic seat depth/ seat height issues that aren't visible until someone actually sits down

A quick DIY tape-measure job may not cover all possible issues. They tend to surface only during a proper, in-person professional site measurement.

The Singapore-specific factor

Singapore's climate changes what "the right fabric" means. A few things worth knowing before choosing:

  • Leather traps heat. Genuine or faux, leather doesn't breathe, which makes it uncomfortable on a sun-facing bay window seat. It's the same reason a car's leather seats feel unbearable after being parked in the sun.

  • Natural fibers like cotton and linen breathe better, allowing heat to pass through rather than trapping it against skin.
  • A blend of natural and synthetic fibers is often a practical middle ground with durability from the synthetic component and breathability from the natural one.

  • UV exposure degrades fabric. Fading, fiber weakening and yellowing effects are cumulative, so they're rarely obvious until a cushion has already been sat on for a few months. For east- or west-facing bay windows especially west-facing, it's worth specifically asking for an indoor-outdoor performance fabric rather than a standard indoor upholstery fabric.

If your bay window gets direct morning or afternoon sun, this matters more than color or texture when choosing upholstery.

Case study: a 46.1cm seat that needed more

On one recent project, our client's seat measured 46.1cm deep and we advised that it was a little shallow for genuinely comfortable sitting, even for occasional or task use.

The solution was a wall wrap that extended the seat depth by an odd 5.9cm, bringing the total sitting depth to 52cm. It's a small adjustment on paper, but it's the difference between a cushion that's merely adequate and one that's actually comfortable to sit in.

Key takeaway: seat depth isn't just a measurement. A cushion that "fits" the window opening can still be too shallow to sit on comfortably.

Case study: designing around built-in drawers

The same project had built-in drawers directly beneath the window seat. This meant the wall wrap's height had to be carefully planned at a 17cm tall, deliberately kept short enough that it wouldn't cover or obstruct the drawers below.

Key takeaway: a wall wrap isn't just a finishing detail. Its height and placement need to work with the carpentry underneath it, not just the window above it.

Choosing a fabric that isn't the same as everyone else's

White, grey, green, and brown colour options has become the default choice for upholstered furniture. It's a safe option, but not a distinctive one.

On the case-study project above, the client chose to skip a popular white boucle in favour of a fabric with a different hand feel, chosen from our wider range of textures and colors. The result matches the room better, rather than defaulting to whatever's most common online.

Why we measure every project on site

Numbers like 46.1cm, 5.9cm, 17cm, aren't visible in a finished photo. But they're the difference between a cushion that fits and one that just sits there.

That's why every confirmed custom seat cushion project starts with a free, in-person site measurement rather than customer-supplied measurements.

Even when a measurement doesn't go exactly to plan (which is rare, and has mostly occurred with certain feather-filled cushions) responsibility for correcting it sits with us, not our customer.

Frequently asked questions

Why is measuring a bay window for a seat cushion difficult?
Bay windows often have subtle variations in depth, irregular notches, or corners that aren't a true right angle. These details are easy to miss with a standard tape measure and are typically only caught during an in-person site visit.

Is leather a good choice for a bay window seat cushion in Singapore?
Generally, no. Leather doesn't breathe, so it traps heat. Natural fibers like cotton and linen, or a natural-synthetic blend, are usually more comfortable.

What fabric should I use for an east- or west-facing bay window seat?
An indoor-outdoor performance fabric is usually a better choice than standard indoor upholstery since it's engineered for UV and fade resistance while still looking and feeling like typical indoor fabric. 

Should I order curtains or a seat cushion first?
It's worth planning both together. Curtains installed before the cushion's final height is confirmed can end up too long, resulting in excess fabric spilling messily over the finished seat.

What is a wall wrap, and why does it matter?
A wall wrap is fabric that extends from the cushion up the adjoining wall, both as a finishing detail and, in some cases, to add usable seat depth. Its size needs to account for nearby fixtures — outlets, skirting boards, curtains, or built-in drawers — so it doesn't interfere with them.

What if my window seat feels too shallow to sit on comfortably?
A shallow seat can often be corrected with a wall wrap that extends the sitting depth by a few centimeters.

Do I need to measure my own bay window before ordering a cushion?
No, an in-person site measurement removes the need for a customer to measure the space themselves, and accounts for irregularities that are easy to miss without professional tools and experience.

What if the cushion doesn't fit once it's made?
This is rare, but if it happens, the responsibility for fixing it, whether adjusting or remaking the cushion, sits with the maker, not the customer.

  • Spare Sofa Covers or Performance Fabric for you...

    What does performance fabric actually do? It repels liquid and stains. Spill juice on it and the liquid sits on the surface for a while instead of soaking in, which gives you time to blot it away. For a home with young children that's a useful feature to have. We used Aquaclean's recycled linen collection for this project. It's liquid and stain repellent. We tested it in our studio before the clients committed.  What do spare covers do? It means that you're never without covers. While one set is being laundered the other is on the sofa. Nobody sits on bare cushions for a week. They also help with wear. The seat everyone fights for shows it first, with faded colour and a tired surface. Replacing a worn cover later means a scramble to re-measure and re-match the fabric. A spare set ordered while the cushions are being made spares you that, because the measurements and fabric are already settled. Which one should you pick? YOUR MAIN WORRY BETTER CHOICE WHY Juice and drink spills from small children Performance fabric You can blot before it soaks in A sofa that smells or looks tired Spare covers Launder one set while the other is in use One seat that everyone fights for Spare covers Swapping sets spreads the wear A light colour you love but don't trust Performance fabric Spills are what stand between you and cream Wanting a different look now and then Spare covers Change the colour and keep the sofa A tighter budget Performance fabric One set costs less than two Why our clients chose both Our clients are a couple with two young children. Their interior designer, HouseofChais, built them a conversation pit sofa and they came to us for custom seat and back cushions. For the covers they chose Aquaclean's recycled linen in a creamy white. Then they ordered a second set in a pastel sage. The first reason was practical: the second set goes on while the first is being laundered.  The second reason was colour: Our client picked a different shade for the spare set because she wanted it to feel like a change. An identical spare would only be a replacement. In a sage green, it also feels like a small refresh. Having both options is probably excessive for many households. But it made sense for our clients because owning a conversation pit isn't something you replace in a few years, and a cream sofa will meet a lot of life with two small children around. Had they needed to pick one, we would have steered them to performance fabric. Why does a different colour feel like a change? There's no magic in it. People get used to what surrounds them and the pleasure fades. Psychologists call this hedonic adaptation. The sofa you loved in March is just a sofa by September. Swapping a cover resets that. The room is the same and so is the layout, but the colour is new, so you notice it again. It also hands you a small decision, and a choice you make yourself often feels better than one that was made for you. Frequently asked questions Is performance fabric waterproof? No. It's liquid-repellent. That buys you time to blot a spill before it soaks in. Why buy a second set of sofa covers? So you're never without covers. One set goes on while the other is being laundered. A different colour for the second set also gives you a change without replacing the sofa. Can I use a light colour if I have young children? Yes, if the fabric is performance fabric. A light colour in a standard fabric is a harder bet. If you're in Singapore and weighing this up, visit the Blafink studio. Bring a glass of something. We'll let you spill it.
