What to look at

  • Size: the mattress must match the slatted base; the most common are 90×200, 140×200 and 160×200 cm. For a double bed consider two separate mattresses if you each sleep differently.
  • Firmness: every maker labels it their own way (grades, letters, words). A heavier person and back or stomach sleeping usually need a firmer mattress, a lighter person and side sleeping a softer one.
  • Two-sided firmness: a mattress with two sides (e.g. firm and medium) lets you try both without another purchase.
  • Material: cold foam is light and springy, memory (visco) foam shapes to the body and runs warmer, pocket springs ventilate well.
  • Height: a taller mattress usually spreads weight better; check it fits the bed frame and the sheets.
  • Cover: a removable washable cover extends its life; allergy sufferers should ask about the washing temperature.
  • Topper: a thin top layer changes how the bed feels for a fraction of a new mattress, but does not fix a sagging one underneath.

Price bands today

The lowest band holds mattress protectors, toppers and children's mattresses. The middle band holds foam mattresses for a single bed. At the top are wide double-bed mattresses and spring or multi-zone models. Always compare the same size.

Recommended models

Bracketed prices are today's totals; mattresses often ship as bulky goods, so shipping differs more between shops than for other goods.

When the mattress does not suit you

A mattress bought online can be returned within 14 days of delivery without a reason. The EU Court of Justice ruled (case C-681/17) that removing the protective film from a mattress does not rule out withdrawal; you are liable, though, for any loss of value beyond normal trying.

You pay return shipping of bulky goods unless the shop says otherwise; for a mattress that can be a noticeable sum. Some shops voluntarily offer a longer trial; their terms say so.

Common mistakes

  • Comparing prices of different sizes or heights.
  • Choosing by the word 'orthopaedic'; it is not a protected term.
  • Putting a new mattress on an old sagging base.
  • Not counting bulky shipping and the cost of returning it.
  • Throwing away the packaging right after unpacking; it helps with a return.

Questions fréquentes

How firm a mattress should I choose?

A heavier person and back or stomach sleeping usually need a firmer mattress, a lighter person and side sleeping a softer one. A two-sided mattress lets you try two firmness levels.

Can I return a mattress after removing the film?

Yes. Under EU Court of Justice judgment C-681/17 removing the film does not rule out the 14-day withdrawal.

Does a topper help?

It changes the feel, typically softening a firm mattress. It does not replace a sagging or damaged one.

Why are protectors among mattresses?

Shops file them in the same category; always compare the same type and size.
