IKEA Size vs UK Size Bed Frames in Singapore: What Is the Difference?

When buying a new bed frame in Singapore, you may come across two different sizing systems: IKEA size and UK size.

Although both retailers may describe a bed as Single, Super Single, Queen or King, the actual dimensions may not be the same. A mattress purchased from a local furniture retailer may not fit properly on an IKEA bed frame, while an IKEA mattress may be too long or too wide for a standard Singapore bed frame.

This guide compares IKEA and UK-style bed frame sizes, explains why the names can be confusing and shows you how to check whether your mattress and bed frame are compatible.

Quick Comparison: IKEA vs UK-Style Bed Frame Sizes

In Singapore, the term “UK size” is often used informally to describe the traditional imperial-based sizes adopted by many local furniture and mattress retailers.

The measurements below refer to the mattress size or sleeping platform that the bed frame is designed to support. They do not represent the complete external dimensions of the frame.

Bed category	IKEA Singapore size	Common UK-style/Singapore size	Main difference
Single	90 × 200 cm	91 × 190 cm	IKEA is about 1 cm narrower and 10 cm longer
Super Single	120 × 200 cm	107 × 190 cm	IKEA is about 13 cm wider and 10 cm longer
Queen	150 × 200 cm	152 × 190 cm	IKEA is about 2 cm narrower and 10 cm longer
King	180 × 200 cm	183 × 190 cm	IKEA is about 3 cm narrower and 10 cm longer

IKEA Singapore currently lists bed frames using dimensions such as 90 × 200 cm, 120 × 200 cm, 150 × 200 cm and 180 × 200 cm.

Lulu Furniture and many other local retailers use the standard Singapore dimensions of approximately 91 × 190 cm for Single, 107 × 190 cm for Super Single, 152 × 190 cm for Queen and 182–183 × 190 cm for King.

The key takeaway is simple:

An IKEA bed frame and a UK-style Singapore bed frame are generally not interchangeable, even when they have the same size name.

Bed Frame Size Does Not Mean Overall Frame Size

A bed frame listed as 150 × 200 cm is designed to support a 150 × 200 cm mattress. It does not mean the complete bed frame measures exactly 150 × 200 cm.

The external dimensions are usually larger because of components such as:

Headboard
Footboard
Side panels
Upholstery
Storage drawers
Shelves
Decorative borders
Built-in bedside tables

For example, one Lulu Furniture storage bed has a Queen-size tatami version measuring approximately 152 × 191 cm, while the version with a headboard measures approximately 152 × 211 cm. The headboard adds around 20 cm to the total length even though both versions use the same Queen mattress size.

When measuring your bedroom, you therefore need to check two separate specifications:

The mattress size supported by the bed frame
The complete external dimensions of the bed frame

IKEA Single vs UK-Style Single Bed Frame

IKEA Single

Matching mattress size: 90 × 200 cm

UK-style Singapore Single

Matching mattress size: approximately 91 × 190 cm

The widths are very similar, but the IKEA Single is approximately 10 cm longer.

This creates two possible compatibility problems.

Using a Singapore Single mattress on an IKEA frame

A 91 × 190 cm local Single mattress may be approximately 1 cm wider than the IKEA sleeping platform. It will also be approximately 10 cm shorter, potentially leaving a visible gap at the headboard or footboard.

Whether the extra width causes a serious issue depends on the frame design. A flat platform may provide slightly more flexibility, while a recessed frame with raised borders may not accommodate the mattress properly.

Using an IKEA mattress on a local Single frame

A 90 × 200 cm IKEA mattress is approximately 10 cm longer than a standard 91 × 190 cm local frame.

It may extend beyond the platform, press against the headboard and footboard or fail to lie flat.

For this reason, an IKEA Single mattress should generally be paired with a 90 × 200 cm IKEA-size bed frame.

IKEA Super Single vs UK-Style Super Single

IKEA Super Single

Matching mattress size: 120 × 200 cm

UK-style Singapore Super Single

Matching mattress size: approximately 107 × 190 cm

This category has the biggest difference.

An IKEA Super Single is approximately:

13 cm wider
10 cm longer

A standard Singapore Super Single mattress will leave significant gaps when placed on a 120 × 200 cm IKEA frame.

Likewise, a 120 × 200 cm IKEA mattress will not fit on a standard 107 × 190 cm Super Single bed frame.

Do not assume that the two products are compatible simply because both are advertised as “Super Single”.

A 13 cm difference in width is substantial and cannot be corrected by using larger bedsheets, mattress protectors or toppers.

IKEA Queen vs UK-Style Queen Bed Frame

IKEA Queen

Matching mattress size: 150 × 200 cm

UK-style Singapore Queen

Matching mattress size: approximately 152 × 190 cm

An IKEA Queen is approximately 2 cm narrower and 10 cm longer than a standard Singapore Queen.

Singapore Queen mattress on an IKEA Queen frame

A 152 × 190 cm mattress may be too wide for a recessed 150 × 200 cm IKEA frame. It will also be around 10 cm shorter than the intended sleeping platform.

Even though a 2 cm width difference may seem small, forcing a mattress into a narrower frame may compress its edges or prevent it from sitting flat.

IKEA Queen mattress on a Singapore Queen frame

A 150 × 200 cm mattress will generally be too long for a 152 × 190 cm local frame. It may also leave a small gap along the sides.

The two Queen sizes should therefore not be treated as interchangeable.

IKEA King vs UK-Style King Bed Frame

IKEA King

Matching mattress size: 180 × 200 cm

UK-style Singapore King

Matching mattress size: approximately 183 × 190 cm

A local King mattress is approximately 3 cm wider but 10 cm shorter than an IKEA King.

A 183 × 190 cm Singapore King mattress may be too wide for a 180 × 200 cm IKEA frame and leave a large lengthwise gap.

An IKEA 180 × 200 cm mattress may be too long for a local King frame designed around a 183 × 190 cm sleeping platform.

King beds are large and costly to transport, so checking the exact dimensions before purchasing is particularly important.

An Important Note About Actual UK Bed Sizes

The expression “UK size” can cause confusion in Singapore.

Many Singapore sellers use “UK size” to describe the familiar local imperial-derived dimensions. However, the current official UK naming system is different.

Standard UK mattress and matching bed sizes include:

Official UK bed name	Mattress dimensions
Standard Single	90 × 190 cm
Small Double	120 × 190 cm
Standard Double	135 × 190 cm
King	150 × 200 cm
Super King	180 × 200 cm

IKEA UK states that its Standard Single, Small Double and Standard Double mattresses are 190 cm long, while its King and Super King mattresses are 200 cm long.

This means that some IKEA Singapore dimensions match an official UK dimension but carry a different name.

IKEA Singapore name	Size	Equivalent official UK name
IKEA Single	90 × 200 cm	Junior, bunk or loft-bed size rather than standard UK Single
IKEA Super Single	120 × 200 cm	No direct common UK adult-bed equivalent
IKEA Queen	150 × 200 cm	UK King
IKEA King	180 × 200 cm	UK Super King

For example, a 150 × 200 cm bed may be called:

Queen in IKEA Singapore
King in the United Kingdom

A 180 × 200 cm bed may be called:

King in IKEA Singapore
Super King in the United Kingdom

This is why shoppers should always compare centimetres instead of relying only on terms such as Queen or King.

Will a UK-Style Mattress Fit an IKEA Bed Frame?

Usually, no.

A mattress will fit properly only when its width and length match the sleeping platform specified for the bed frame.

Potential problems include:

Mattress overhanging the frame
Mattress edges becoming compressed
Large gaps around the mattress
Mattress moving during use
Difficulty fitting bedsheets properly
Reduced support at the mattress edges
An untidy or unfinished appearance

Some flat platform beds may tolerate a very small variation, but you should not assume compatibility without checking the manufacturer’s specifications.

Frames with raised edges, recessed platforms or fixed borders normally require a much more precise fit.

Will an IKEA Mattress Fit a UK-Style Bed Frame?

In most cases, it will not fit correctly.

Most adult IKEA Singapore mattresses are 200 cm long, while standard local Single, Super Single, Queen and King mattresses are generally around 190 cm long.

The extra 10 cm means the IKEA mattress may:

Extend beyond the end of the frame
Bend against the headboard or footboard
Fail to receive proper support
Sit unevenly on the sleeping platform

An oversized mattress should not be forced into a smaller frame. Constant compression may affect its shape, comfort and durability.

What About Bed Frames Without Raised Borders?

A simple platform or divan-style bed may provide slightly more flexibility than a recessed frame.

For example, a mattress that is 1 or 2 cm narrower than the platform may still be usable if it is properly supported and does not move excessively.

However, length differences of approximately 10 cm and width differences of 13 cm are too large to ignore.

Before using a differently sized mattress, check:

Whether the entire mattress base is supported
Whether any part of the mattress hangs over the frame
Whether the mattress slides during use
Whether the frame manufacturer permits that mattress size
Whether the variation affects the product warranty

The safest option is always to use the exact mattress size recommended for the bed frame.

Bedsheets and Mattress Protectors May Also Be Different

Even when a mattress appears to fit reasonably well, its bedding may not.

A fitted sheet designed for a 152 × 190 cm Singapore Queen mattress may not fit a 150 × 200 cm IKEA Queen mattress. It may be too short to stretch over the corners or loose along the sides.

The same issue applies to:

Mattress protectors
Mattress toppers
Fitted sheets
Bedspreads
Divan covers
Waterproof mattress covers

You should check three measurements when buying fitted bedding:

Mattress width
Mattress length
Mattress thickness

A thick mattress may require a deep-pocket fitted sheet even when the width and length are correct.

How to Measure an Existing Bed Frame

Before ordering a replacement mattress, remove the current mattress and measure the actual sleeping platform.

Step 1: Measure the internal width

Measure from the inside of the left frame border to the inside of the right frame border.

Do not measure the complete external width of the bed.

Step 2: Measure the internal length

Measure from the inside of the headboard end to the inside of the footboard end.

For flat platform beds without borders, measure the area designed to support the mattress.

Step 3: Check for raised edges

Some bed frames have borders that hold the mattress in position. These reduce the usable sleeping-platform area and require a more exact mattress fit.

Step 4: Measure the complete external frame

Measure the overall width and length separately to confirm that the bed will fit in your bedroom.

Step 5: Record everything in centimetres

Do not rely on rough measurements in feet or size names alone. A difference of just a few centimetres can determine whether a mattress fits correctly.

How to Measure Your Bedroom Before Buying

Checking mattress compatibility is only one part of choosing a bed frame. You must also ensure that the complete frame fits comfortably inside the room.

Measure the space needed for:

Headboard thickness
Footboard
Bedside tables
Wardrobe doors
Bedroom doors
Storage drawers
Pull-out beds
Electrical sockets
Walking paths

Use masking tape to mark the complete frame dimensions on the floor. This helps you visualise how much usable space will remain.

For storage beds, open the proposed storage area fully when planning the layout. A drawer that cannot open because of a nearby wall or wardrobe will be difficult to use.

Check the Delivery Route

Large IKEA and UK-style bed frames may be supplied in separate components, but certain headboards and panels can still be difficult to move into the bedroom.

Before ordering, check:

Lift dimensions
Corridor width
Main entrance width
Bedroom doorway
Staircases
Sharp corners
Ceiling height
Built-in cabinets along the delivery route

This is especially important for King-size frames, tall upholstered headboards and one-piece storage platforms.

IKEA vs UK-Style Bed Frame Buying Checklist

Before buying a mattress or frame, confirm the following:

What are the exact mattress dimensions in centimetres?
What mattress size does the frame support?
Are the measurements based on IKEA or local UK-style sizing?
What are the complete external frame dimensions?
Does the frame have raised or recessed borders?
Is the mattress included with the frame?
Is the bed available in the required size?
Will the complete frame fit inside the bedroom?
Is there enough space to open drawers and wardrobe doors?
Can the components pass through the delivery route?
Will your existing fitted sheets and protectors fit?
Does the manufacturer permit any size variation?

Frequently Asked Questions

Are IKEA and UK-style Single bed frames the same size?

No. An IKEA Singapore Single commonly supports a 90 × 200 cm mattress, while a standard Singapore Single supports an approximately 91 × 190 cm mattress.

Is an IKEA Super Single the same as a local Super Single?

No. An IKEA Super Single is commonly 120 × 200 cm, while a standard Singapore Super Single is approximately 107 × 190 cm. The IKEA version is considerably wider and longer.

Is an IKEA Queen the same as a Singapore Queen?

No. An IKEA Queen commonly supports a 150 × 200 cm mattress. A standard Singapore Queen commonly supports a 152 × 190 cm mattress.

Is an IKEA King the same as a Singapore King?

No. An IKEA King is commonly 180 × 200 cm, while a standard Singapore King is approximately 183 × 190 cm.

Is an IKEA Queen the same as a UK King?

In terms of mattress dimensions, yes. Both are commonly 150 × 200 cm. However, the size name differs between IKEA Singapore and the official UK system.

Is an IKEA King the same as a UK Super King?

In terms of mattress dimensions, yes. Both are commonly 180 × 200 cm.

Can I use a shorter mattress on a longer bed frame?

It may physically fit, but it will leave a gap and may move during use. The appearance, support and comfort may also be affected.

Can I customise a mattress to fit an IKEA frame?

Some mattress suppliers may offer customised dimensions. Confirm the precise internal sleeping-platform measurements and allowable manufacturing tolerance before ordering.

Should I measure my mattress or bed frame first?

Measure both. If you are keeping your existing mattress, use its exact dimensions to select the frame. If you are keeping the frame, measure its internal sleeping platform before buying a replacement mattress.

Final Advice: Always Compare the Exact Measurements

The words Single, Super Single, Queen and King are not universal measurements.

The most reliable approach is to ignore the size name temporarily and compare the actual dimensions in centimetres.

Before ordering, remember these three rules:

Match the mattress width and length to the frame’s sleeping platform.
Check the complete external bed-frame dimensions separately.
Do not assume that IKEA and UK-style Singapore products are interchangeable.

At Lulu Furniture, our bed frames and mattresses are available in standard Singapore sizes commonly used by local households. Check the dimensions shown on each product page before ordering, especially when matching a new mattress with an existing bed frame.

Choosing the correct size from the beginning will help prevent unwanted gaps, overhang, delivery complications and the cost of replacing an incompatible mattress or frame.
