Here is the honest answer upfront: what most Singaporeans call a "double bed" and what they actually need are often two different things. A true Double sits at 137 cm wide, a size almost no local retailer stocks as a standard because it falls awkwardly between a Super Single and a Queen. If you have been browsing beds and feeling confused by the labels, that gap in the naming is almost certainly why. This guide untangles the sizing, maps each option to the rooms you are likely working with, and tells you which bed your space can realistically hold, before the delivery lorry arrives.
Quick answer: For most Singapore couples in a standard HDB bedroom, a Queen (152 × 190 cm) hits the sweet spot between sleeping comfort and room circulation. A King (182 × 190 cm) fits comfortably in a 4-room master bedroom or larger but requires careful measurement. A Super Single suits solo sleepers or smaller rooms.
What "Double Bed Size" Actually Means in Singapore
Walk into any local furniture showroom and you will rarely see a product labelled "Double." The international Double standard (roughly 135-138 cm wide) was quietly overtaken by the Queen as the default couples' size, and most Singapore retailers skipped it entirely. What you will find instead is a four-rung ladder: Single (91 × 190 cm), Super Single (107 × 190 cm), Queen (152 × 190 cm), and King (182 × 190 cm).
When a buyer types "double bed size" into a search bar, they almost always mean "a bed big enough for two people." That is a Queen. And occasionally a King. This distinction matters because it changes the shortlist immediately: if you are shopping for a shared bed, you can skip past the Single and Super Single categories and focus your measurements on Queen versus King.
Queen vs King: The Trade-Off Nobody Explains Clearly Enough
The width jump from a Queen to a King is 30 cm, roughly the width of a standard sleeping pillow. That sounds modest. In a bedroom, it is the difference between a room that feels airy and one where you are squeezing past the footboard every morning to get to the wardrobe.
A King gives each person about 91 cm of personal width, close to a generous single bed each. For couples who move a lot during sleep, have different temperature preferences, or share the bed with a child or a dog, that extra space is genuinely restful. For couples who sleep close together and value a bedroom that does not feel like a furniture showroom floor, a Queen is the more liveable choice in most Singapore flats.
Both sizes share the same 190 cm length (some frames run to 198 cm, always check the product spec). Singapore adults at the taller end should verify this length, as 190 cm leaves limited headroom for anyone approaching that height.
How Room Size Should Drive Your Decision
Singapore bedrooms are smaller than they look in listing photos. A typical 4-room HDB flat is around 90 sqm total, and the master bedroom is one of four or five rooms sharing that footprint. The secondary bedrooms in a 3-room flat are tighter still.
The reliable rule of thumb for sleeping comfort: aim for at least 60 cm of clearance on each side of the bed, and 70 cm at the foot. Those gaps are not generosity, they are the minimum for making a bed, opening a wardrobe door that sits at the foot, and circulating without turning sideways.
Run the numbers before you commit. A Queen frame at 152 cm wide, plus 60 cm on each side, asks for 272 cm of wall-to-wall width. A King frame at 182 cm wide with the same clearances needs 302 cm. Measure your bedroom wall (the one the headboard will sit against) and subtract any wardrobe or door swing that eats into that space. Then measure the opposite wall too, because the 70 cm footboard clearance disappears faster than you expect once a TV console or dresser moves in.
For 5-room and executive flats, or condo bedrooms with more generous proportions, a King is genuinely achievable and often the right call for a master bedroom. For 3-room and smaller resale flats, a Queen is almost always the smarter fit.
The Bed Frame Adds More Space Than You Think
A mattress size is not the same as a bed frame size. Bed frames typically extend 10 to 15 cm beyond the mattress on all or most sides, for the headboard thickness, side rail, and footboard if there is one. A Queen mattress at 152 cm wide inside a frame with a generous side rail becomes a 162-167 cm piece of furniture on your floor plan.
This catches buyers by surprise most often at delivery, not in the showroom where the floor is expansive and the reference objects are absent. Before you confirm your order, check the frame's overall external dimensions in the product specifications, not just the mattress size. If the spec sheet only lists mattress compatibility, call or message the retailer to confirm the frame's footprint.
There is a second delivery risk worth knowing: HDB internal and bedroom doors are typically around 0.8 m wide, and many lift car door openings are a similar width. A King bed frame (particularly one with a solid headboard panel) will often need to be partially or fully disassembled to travel through the lift and along the corridor. Professional assembly services account for this, but it is worth confirming before you buy a floor-model piece that cannot be broken down.
Materials That Suit the Singapore Climate
Bed frame material is not just an aesthetic choice in a country where relative humidity sits around 70 to 85 percent year-round.
Solid wood is beautiful and refinishable, but it moves with humidity, slight expansion and contraction over the seasons is normal. Joinery needs to be well-made or you will hear creaking within a year. Engineered wood and good-quality plywood are dimensionally stable options that hold up well here and are less likely to develop movement over time. Metal frames are durable and generally unaffected by humidity, though thin metal tubing can feel less substantial, and metal in a damp corner (near an aircon drip or a window left open during rain) can corrode if the finish is poor.
Upholstered bed frames look polished and reduce the hard-surface echo in a bedroom, but fabric panels absorb humidity and can attract dust mites in Singapore's climate. If you go this route, look for performance or tightly-woven fabrics and commit to a routine of vacuuming the headboard. Faux leather (PU) is easy to wipe down but can peel at seams after a few years, especially in a warm, humid room. Genuine or top-grain leather breathes slightly better and ages more gracefully, though it sits at a higher price point.
For most Singapore bedrooms, an engineered-wood frame with a fabric or PU upholstered headboard offers the best balance of stability, comfort, and value.

Making the Final Call
There is no single correct answer, but there is usually a clearly better one once you have your measurements. If your bedroom wall-to-wall width is under 280 cm, a Queen is the honest choice for a liveable room. If it clears 300 cm comfortably, a King becomes viable and, for couples who value sleep space, genuinely worth it.
Beyond dimensions, think about who is sleeping in the bed five years from now. A couple planning to start a family may want the King's extra width for the inevitable co-sleeping phase. A solo occupant in a smaller room may find a Super Single or a Queen single-use layout gives them wardrobe and study space that a King would erase.
If you are still uncertain, the most practical thing you can do is lie down on both sizes in a showroom (not sit on the edge, but actually lie down at the same time as your partner) and measure your current bedroom before you go. The Megafurniture showroom at 134 Joo Seng Road has both Queen and King options set up across two levels, daily from 11:30 am to 9 pm, and the team can walk you through frame dimensions and delivery logistics for your specific flat type.

Frequently Asked Questions
Is a Queen bed the same as a double bed in Singapore?
Not exactly. A true Double measures roughly 135-138 cm wide, while a Queen is 152 cm wide. In Singapore, most retailers do not stock a standard Double; the Queen has effectively replaced it as the standard couples' bed size. When local buyers search for "double bed," they usually mean a Queen.
Will a King bed fit in a 4-room HDB master bedroom?
It depends on your specific block and layout, but many 4-room HDB master bedrooms can hold a King (182 cm wide) if you plan carefully. Measure wall-to-wall width and allow at least 60 cm on each side and 70 cm at the foot. Account for the bed frame's actual external dimensions, which typically add 10-15 cm beyond the mattress.
What is the longest mattress available in Singapore?
Standard Singapore mattresses are 190 cm long across all sizes. Some frames and mattresses run to 198 cm, useful if you or your partner is taller. Always check the individual product specification rather than assuming the standard length, and leave a small buffer at the head and foot when planning your room layout.
Can a King bed frame fit through an HDB lift?
Often, but not always without disassembly. HDB lift door openings and internal bedroom doors are typically around 0.8 m wide, which can be tight for a fully assembled King frame, especially one with a wide solid headboard. Professional assembly services disassemble and reassemble the frame in the room, confirm this when booking delivery rather than discovering it on the day.
How do I choose between an upholstered and a wooden bed frame in Singapore's climate?
Engineered wood frames are stable in high humidity and generally low-maintenance. Upholstered frames look soft and warm but fabric panels absorb moisture and dust over time, choose a tightly-woven performance fabric and vacuum regularly. PU leather is wipe-clean but can peel at seams in warm, humid rooms. Solid wood is attractive but moves slightly with seasonal humidity changes; quality joinery matters.
Choosing the right bed size is mostly a maths problem (room width, clearances, frame dimensions) with a comfort preference on top. Get the numbers right first, then pick the style. If you want to see how Queen and King frames actually feel and fit before committing, the Joo Seng showroom is open daily.
