Buying a mattress 140x210? Here's what you need to know
A mattress 140x210 sits between a standard double and a wider king size, with the added benefit of extra length. The width of 140 cm offers a comfortable sleeping surface for two people or generous space for one, while the length of 210 cm ensures taller sleepers have all the legroom they need. It's a practical choice for anyone who wants more than a standard 200 cm length without going all the way up to a 160 or 180 cm wide bed.
What makes a good mattress 140x210?
At Tuur®, we deliberately choose 100% natural latex as the core material for every mattress 140x210. Why? Natural latex breathes naturally, springs back to its original shape every morning and has an average lifespan of 15 to 20 years.
That's twice as long as an average polyurethane mattress. What's more, a mattress 140x210 made from natural latex is hypoallergenic and naturally dust mite-resistant, without any chemical treatment. A major advantage for people with allergies or sensitive skin.
Which firmness level for your mattress 140x210?
Tuur® offers every mattress 140x210 in multiple firmness levels. As a general guideline: side sleepers and lighter individuals typically prefer a softer to medium comfort, while back and stomach sleepers or heavier individuals tend to sleep better on a firmer mattress 140x210.

Mattress 140x210 and your bed frame or boxspring
A mattress 140x210 from Tuur® fits any standard bed frame or boxspring with an internal dimension of 140x210 cm. Our mattresses are compatible with slatted bases, solid bases and boxsprings.
Frequently asked questions about mattress 140x210
A 140x210 cm mattress is an extra-long twijfelaar, suited to solo sleepers who like extra space or couples in a smaller bedroom who do not need or want a full double. The extra length makes this format ideal for taller sleepers who want more comfort without their feet reaching the edge of the mattress. It also works well as a guest bed or in a student room where efficient use of floor space matters.
A 140x210 cm mattress sits between a single and a double: wide enough for one person to sleep very comfortably, and just about sufficient for two people who prefer to sleep close together. A twijfelaar is described as a large single for those who want more space, or a small double for those who need less, and the 140x210 follows the same logic with the addition of extra length. For couples who sleep together regularly, a 160 cm wide mattress offers meaningfully more personal space.
A 140x210 cm mattress requires a duvet measuring 200x220 cm, which is a standard extra-length format. A standard 200x200 cm duvet is too short for a 140x210 mattress; the 200x220 cm size is the correct fit. Always check the mattress depth noted on the fitted sheet label to ensure it matches the thickness of your mattress.
Yes, every Tuur® mattress comes with a 120-night sleep trial. If it does not suit you, we collect it free of charge and refund you in full. Returns are always free.
A 140x210 cm mattress is 10 cm longer than the standard 140x200. For sleepers taller than 185 cm, those 10 cm mean the difference between lying fully supported and feet pressing against the end of the mattress. The 140x210 gives taller sleepers the length they need without having to step up to a wider format.
