Baby and Child Formats: What You Need to Know

Baby Mattress (60×120 cm)

The 60×120 cm baby mattress is the standard for cradle beds in France. It meets the safety regulations for infants up to 2 years old. This format is required to be firm to avoid any risk of suffocation.

Key points:

Recommended thickness: 8 to 12 cm
Suitable materials: high resilience foam, coconut, natural latex
Important certifications: OEKO-TEX Standard 100, CertiPUR

Child Mattress (80×160 and 90×190 cm)

For children aged 6 to 12 years, the 80×160 cm format provides enough space to grow. From the age of 12, transitioning to the 90×190 cm (junior format) is advised, especially if the child is over 1.50 m tall.

Adult Single Formats

90×190 cm and 90×200 cm: What's the Difference?

The 90×190 cm remains common in older homes and guest rooms. However, the 90×200 cm is now the standard for adults, offering an additional 10 cm in length, essential for people over 1.75 m.

Golden rule: your mattress should measure at least 10 to 15 cm longer than your height.

100×200 cm: The Extra Comfort

This format is gaining popularity. With an additional 10 cm in width compared to the 90×200, it offers significantly better comfort for those who move a lot while sleeping or share their bed with a pet.

Double Formats: Detailed Guide

140×190 cm vs 140×200 cm

These two formats are often confused. The 10 cm length difference may seem trivial, but it is crucial:

140×190 cm: suitable for couples where neither exceeds 1.75 m. A common format in older Parisian apartments with inherited bed frames.
140×200 cm: the recommended standard for any couple, especially if one partner is over 1.75 m. The price difference is generally minimal (10 to 30 EUR).

Our advice: if you are changing your mattress, always opt for the 140×200 cm rather than the 140×190 cm.

160×200 cm: The European Standard for Couples

The 160×200 cm format (also called Queen Size in France) is the best-selling for couples. Each person has 80 cm of width, which corresponds to the width of a comfort single bed.

It is the ideal format for:

Couples where one sleeps restlessly
People with back problems who need space
Families who occasionally have children in bed

180×200 cm and 200×200 cm: The Great Comfort

These formats, often referred to as King Size, offer exceptional sleeping space. Each person has 90 to 100 cm, equivalent to a wide single bed.

Caution: these formats require a room of at least 12 to 15 m² to avoid crowding the space. Also, check that you can get this mattress into your home (staircase, elevator).

How to Choose Your Mattress Size

Criterion 1: Your Body Type

The basic rule is simple: your mattress should be at least your height + 15 cm in length.

Your height	Minimum recommended length
Up to 1.70 m	185 cm (190 cm minimum)
1.70 m to 1.80 m	195 cm (200 cm recommended)
1.80 m to 1.90 m	200 cm minimum
Over 1.90 m	200 cm (consider custom size)

Criterion 2: Number of People

Alone: 90×200 cm (tight budget) or 100×200 cm (comfort)
In a harmonious couple: 140×200 cm minimum
In a couple with different sleeping styles: 160×200 cm ideal
With occasional children/pets: 160×200 cm or 180×200 cm

Criterion 3: The Size of Your Room

Here are the minimum recommended areas according to mattress size:

Mattress size	Minimum room area
90×200 cm	9 m²
140×200 cm	10 m²
160×200 cm	12 m²
180×200 cm	14 m²
200×200 cm	16 m²

These dimensions assume maintaining a clearance of at least 70 cm on each side of the bed for comfortable movement.

Bed Base and Bedding Compatibility

Slatted Bed Base

The slatted bed base is the most common in France. It adapts to all mattress sizes. For queen and king formats, ensure that the bed base has a central support slat to prevent sagging in the middle.

Tip: with a memory foam or latex mattress, space the slats 4 to 6 cm apart maximum for optimal support.

Box Spring

This type of bed base, covered in fabric, is fixed and offers a uniform surface. It is suitable for all types of mattresses. Be cautious with natural latex mattresses that require a ventilated surface - prefer a slatted bed base in this case.

Bed Frames and Headboards

Before any purchase, measure the inside of your bed frame precisely. Tolerances are generally +/- 1 cm. A mattress that is too small in a frame may slide; too large, it won't fit.

Good to know: the dimensions of European bed frames are standardized to the same sizes as mattresses (90, 140, 160, 180 cm).

Sheets and Mattress Protectors

Be sure to check the compatibility of your bedding:

Standard fitted sheets 140×190 cm do NOT fit a 140×200 cm mattress
The thickness of the mattress is also crucial: fitted sheets come in depths of 25, 30, 35, and 40 cm

Mattress Prices by Size

The price of a mattress varies significantly depending on its size. Here is an estimate of price ranges in 2026:

Size	Entry-level	Mid-range	High-end
90×200 cm	100 - 200 EUR	300 - 500 EUR	700 - 1,500 EUR
140×200 cm	150 - 300 EUR	400 - 700 EUR	900 - 2,000 EUR
160×200 cm	200 - 400 EUR	500 - 800 EUR	1,000 - 2,500 EUR
180×200 cm	250 - 450 EUR	600 - 1,000 EUR	1,200 - 3,000 EUR
200×200 cm	300 - 500 EUR	700 - 1,200 EUR	1,500 - 3,500 EUR

Budget tip: the extra cost between a 140×200 and a 160×200 cm is generally 50 to 150 EUR depending on the brands. It's often an investment worth making for a couple.

Special Cases and Custom Sizes

Large Sizes (Over 200 cm)

People over 1.90 m may feel cramped even on a 200 cm mattress. Some brands offer extended formats of 210 or 220 cm. Expect an additional cost of 20 to 40% compared to the standard size.

Bunk Beds and Cabins

These beds often use non-standard formats: 80×180, 80×190, 90×180 cm. Always measure the inside of the frame before ordering.

Murphy Beds

These systems have their own weight and thickness constraints. The mattress should generally not exceed 18 cm in thickness to function properly with the lifting mechanism.

FAQ: Mattress Sizes

What is the standard size of a double mattress?

160×200 cm is the standard size for a couple in France. It is the most sold and recommended format by sleep specialists, as it provides each person with space equivalent to a single bed.

What is the difference between 140×190 and 140×200?

10 cm of extra length, recommended for people over 1.80 m. If your current bedding is 140×190, check if your bed frame can accommodate a 140×200 before ordering.

Can you find mattresses in 160×190 cm?

This format exists but is uncommon. It is often associated with old bed frames. If possible, prefer to switch to 160×200 cm for better comfort.

Is a 160×200 mattress suitable for sleeping alone?

Yes, absolutely. Sleeping alone on a large mattress has no drawbacks - on the contrary, you benefit from generous sleeping space. The only constraint is the size of the room.

How do I measure my bed base before buying?

Measure the inside of your existing frame or bed base in length and width. Add 1 to 2 cm of margin. If your bed base measures 159×199 cm inside, a 160×200 cm mattress will fit perfectly.

Conclusion: Which Size to Choose?

The choice of mattress size primarily depends on your body type, lifestyle, and room. In summary:

Alone: 90×200 cm minimum, 100×200 if possible
In a couple: 160×200 cm is the ideal standard
Great comfort in a couple: 180×200 cm if the room allows
With children: always check the size + 15 cm

Investing in the right format is also investing in the quality of your sleep for the next 10 years. Don't skimp on a few extra centimeters - you won't regret it.
