Best Mattress for HDB Flats in Singapore: Size Guide by Room Type
Over 80% of Singaporeans live in HDB flats. But most mattress guides are written for generic bedrooms — they don't tell you whether a king mattress will actually fit in your room, or if it'll even make it up the HDB lift.
This guide covers what fits where, so you don't end up with a mattress that's too big for the room or stuck in the lobby.
A Note on HDB Dimensions
HDB bedroom sizes vary a lot depending on your flat type, the era it was built, and the specific project. Older resale flats can be quite different from newer BTOs. Always measure your actual room before buying. The recommendations below are based on typical ranges, not exact specs.
HDB Master Bedroom
Most HDB master bedrooms fall in the 13-16 sqm range, with newer BTOs trending smaller.
Queen (152cm x 190cm) fits most master bedrooms comfortably. You'll typically have space for two side tables and a wardrobe with walking room on both sides.
King (183cm x 190cm) works in larger master bedrooms — common in 5-room flats and older resale units. In smaller 3-room or 4-room master bedrooms, a king will fit but you may lose a side table or have tight clearance on one side. Measure first: you want at least 50-60cm of walking space on the sides you use to get in and out of bed.
Quick test: Measure your room width. Subtract 183cm (king) or 152cm (queen). Divide what's left between both sides. That's your walking space per side.
HDB Common Bedrooms
Common bedrooms are noticeably smaller — typically 7-10 sqm across all flat types.
Single (91cm x 190cm) — leaves room for a study desk and wardrobe. Best for children's rooms.
Super Single (107cm x 190cm) — only 16cm wider than a single but noticeably more comfortable. Still fits a small desk and wardrobe. Best for teenagers and adults in common bedrooms.
Don't put a queen in a common bedroom unless you've measured and confirmed the space works. In most HDB common bedrooms, a queen will leave almost no room for anything else.
Will Your Mattress Fit in the HDB Lift?
This catches a lot of people off guard. Standard HDB lift internal dimensions are approximately 1.1m wide x 1.4m deep.
| Mattress Size | Dimensions | Fits in HDB Lift? |
|---|---|---|
| Single | 91cm x 190cm | Yes — stands upright |
| Super Single | 107cm x 190cm | Yes — stands upright |
| Queen | 152cm x 190cm | Yes — tilted diagonally |
| King | 183cm x 190cm | Tight — may need service lift |
For king size: Check if your block has a service or cargo lift. Most newer BTOs do. For older blocks without one, the mattress may need to go up the stairs. Confirm with your delivery team before purchase.
Serta offers free white-glove delivery — our team will check your lift situation before delivery day.

Frequently Asked Questions
Can a king size mattress fit in a 4-room HDB master bedroom?
It depends on your specific layout. A king mattress is 183cm wide — measure your room and make sure you have at least 50-60cm of walking space on the sides you need to access. In many 4-room master bedrooms, queen (152cm) is the more practical choice. In 5-room flats, king usually fits well.
What mattress size is best for an HDB common bedroom?
Single (91cm x 190cm) for children, or Super Single (107cm x 190cm) for teenagers and adults. Most HDB common bedrooms are 7-10 sqm — a queen would leave almost no space for a desk or wardrobe.
Will a king size mattress fit in the HDB lift?
Standard HDB lifts are approximately 1.1m x 1.4m. A king mattress (183cm x 190cm) is a tight fit and may need a service or cargo lift. Newer BTO blocks usually have one. Serta's delivery team will assess your lift before delivery.
How much does it cost to outfit an entire HDB with mattresses?
With Serta SleepTrue, a queen for the master bedroom ($1,088) plus two singles for common bedrooms ($788 each) comes to $2,664. A king plus two super singles would be $2,964. All sizes include free delivery and a 10-year warranty.
