King Size Bed Singapore: Worth Upgrading from Queen? 183×190cm Guide

A king size bed in Singapore measures 183 × 190 cm — that's 31cm wider than a queen but the same length. If you're deciding between the two, the real question isn't size. It's whether your bedroom can fit it and whether the upgrade is worth it.
Short answer: if your room is at least 3.5m wide, a king fits comfortably. And at Serta, a king is only $100 more than a queen ($1,188 vs $1,088 for SleepTrue).
Singapore King Size Dimensions
| Size | Width × Length | Common Use |
|---|---|---|
| Queen | 152 × 190 cm | Couples, standard |
| King | 183 × 190 cm | Couples wanting space |
Important: Singapore king size (183 × 190 cm) is different from US king (193 × 203 cm) and UK king (150 × 200 cm). Always check dimensions when buying imported bedding or frames.
Does a King Fit Your Bedroom?
You need at least 60cm clearance on each side of the bed for walking space, plus room at the foot.
Minimum room size for a king bed: approximately 3.5m × 3.5m (12.25 sqm)
HDB Bedrooms
- Master bedroom (most 4-room and above): Usually fits a king. Most HDB master bedrooms are 3.5m+ wide.
- 3-room HDB master bedroom: Tight. Measure before committing.
- Common bedrooms: Too small for king. Stick to queen or super single.
Condo Bedrooms
Most condo master bedrooms comfortably fit a king. Some even accommodate a king with side tables on both sides.
Pro tip: Measure your bedroom doorway too. Some older HDB doors are narrow. Your mattress needs to fit through — Serta mattresses compress for delivery, so this usually isn't an issue.
King vs Queen: Is It Worth $100 More?
Here's what you actually get with 31cm extra width:
Yes, Upgrade If:
- You're a couple and one person moves a lot — 31cm extra means fewer disturbances
- You have kids or pets who end up in your bed
- You're a larger build — more personal space matters for comfort
- Your room fits it — no point squeezing a king into a room with no walking space
- You want hotel-level comfort — hotels use king beds because guests sleep better with more space
Stay with Queen If:
- Your bedroom is under 3.5m wide — a cramped room defeats the purpose
- You need space for other furniture — wardrobes, dressers, study desks
- You prefer a cozier feel — some couples actually prefer sleeping closer
The Price Difference Is Smaller Than You Think
Across most mattress brands, the jump from queen to king is typically only $100–$200. At Serta, the SleepTrue upgrade is just $100. Premium collections like iPedic have a similarly modest jump.
Over a 10-year mattress lifespan, that works out to about $10–$20/year for significantly better sleep. Visit a showroom to compare collections and find the right fit for your budget.
Why Hotels Use King Beds
There's a reason Marriott, Hilton, Conrad, and Resorts World Sentosa all use king beds in their premium rooms — and they all use Serta mattresses. More space means better sleep, fewer partner disturbances, and higher guest satisfaction scores.
You can get the same hotel-grade sleep at home. Read more about which hotels use Serta.
Cooling a King Bed in Singapore
A larger bed means more surface area — which can actually help with heat dissipation. Serta's CoolTech gel-infused memory foam and individually wrapped coils allow airflow through the entire mattress, keeping you cool in Singapore's tropical climate.
