How to choose the best mattress for you: what to check before you buy

There is no single best mattress. The best mattress is the one that is comfortable for your body and the way you sleep, and that you can test well enough before you are committed to it. This guide lists what to look up for each mattress you are considering, before you pay, so you can compare them in the same way.

Why the adverts and the reviews are not enough

Mattress adverts show the best result a mattress can reach. The detailed terms often say something different. For example:

Many mattress review websites also earn money when readers buy through their links. That doesn't make them wrong, but it is a reason to check the same things for every mattress yourself, using the maker's own terms.

Before you look at any mattress

Write down your answers to these four points. They decide which checks in the list matter most to you.

The checklist

The checks are in three groups. Must have means a problem here can make it hard to use or costly to fix. Nice to have means it makes a real difference for many people. Optional means it only matters to some people. When you open the checklist in NeutralPick, you can move any check to a different group to match your answers above.

The button opens this checklist in NeutralPick. There you can:

  1. Remove the checks that don't matter to you, add your own, and move checks between groups.
  2. Add each mattress you are considering.
  3. For each mattress, fill in what you found on the maker's website, its support pages and the shop's product page.
  4. See every mattress side by side.

Claims to look at carefully

Adverts and product pages often describe the points below in vague terms. When you see one, look for the specific information shown here. If you cannot find it, assume the answer is "no" or "only partly".

What to do with what you found

  1. Put all the mattresses side by side.
  2. Look at the Must have checks first. If a mattress gets a No on one of your must-haves, remove it, however good the rest looks. Look closely at any Partial.
  3. If you can, lie on the ones left in a shop, in your usual sleeping position, for several minutes each.
  4. Before you buy, save a copy of the trial, return and warranty terms.
