How to Test a Mattress Before Buying

Quick answer

Lie in your usual sleeping positions for at least 10 to 15 minutes, with your partner and in your own pillow if possible; check spine alignment, pressure at shoulders and hips and ease of turning. A home trial is more reliable than a short shop test.

Key points

  • In the shop. Lie on your side, back and (if you use it) stomach.
  • Time and partner. A few minutes is not enough. Try 10 to 15 minutes, together, and move around.
  • At home. Give a new mattress a few weeks if the trial allows; bodies adapt.

In the shop

Lie on your side, back and (if you use it) stomach. Ask someone to check your spine looks straight when you lie on your side and back.

Time and partner

A few minutes is not enough. Try 10 to 15 minutes, together, and move around.

At home

Give a new mattress a few weeks if the trial allows; bodies adapt.

Frequently asked questions

How long to adapt?

Often two to four weeks, but stop if it causes pain.

Can I test a custom mattress?

Ask for a sample layer or a similar build.
