Cookie policy

Last updated: 23 September 2026

This page lists the cookies and similar technologies used on mattressunboxed.co.uk, what each one is for, and how you can control them. It works alongside our Privacy Policy, which covers how we handle personal data more broadly.

TLDR

We use as few cookies as we can get away with. A small number are strictly necessary to keep the site secure and to remember your cookie choices. Analytics cookies run only if you say yes. We set no advertising cookies on our pages. When you click through to a retailer, the affiliate network handling that retailer sets its own cookies to attribute the sale, and we explain exactly how that works below.

What cookies are

Cookies are small text files a website stores on your device to remember something about your visit. "Similar technologies" covers things that do the same job a different way, such as browser local storage. UK law (the Privacy and Electronic Communications Regulations, alongside the UK GDPR) requires your consent for any cookie that is not strictly necessary for the site to work.

The cookies we use

Strictly necessary

These keep the site working and secure. They do not need consent and cannot be switched off, because the site does not function properly without them.

Strictly necessary cookies used on this site: each cookie's name, who sets it, what it does, and how long it lasts.
Cookie	Set by	What it does	How long
__cf_bm and related Cloudflare cookies	Cloudflare, our infrastructure and security provider	Distinguishes real visitors from malicious automated traffic and keeps the site secure and fast	Typically 30 minutes
mu_consent_v1 (browser local storage)	Mattress Unboxed	Remembers the cookie choice you made so we do not ask you on every visit	12 months

Analytics (with your consent)

With your consent, we use Google Analytics to understand how the site is used: which pages help people, where visitors arrive from, and what to improve. This data is aggregated; we use it to make the site better, not to identify you. These cookies are blocked until you choose to accept them, and you can change your mind at any time via the Cookie preferences link in the footer.

Analytics cookies set only with your consent: each cookie's name, who sets it, what it does, and how long it lasts.
Cookie	Set by	What it does	How long
_ga	Google Analytics	Distinguishes visitors to count visits and traffic sources	2 years
_ga_DW6TV0PDQK	Google Analytics	Maintains session state for our analytics property	2 years

Advertising

We do not set advertising or tracking cookies on our pages. If we introduce clearly labelled advertising in future that involves cookies, we will update this policy and ask for your consent before any such cookie is set.

What happens when you click a retailer link

Mattress Unboxed is funded by affiliate commission, as explained on How We Make Money. When you click a link to a retailer, you briefly pass through the affiliate network that handles that retailer (such as AWIN or TradeDoubler), and the network sets cookies, on its own domain and the retailer's site, so the retailer knows the sale came from us. Those cookies are set by the network and the retailer under their own policies, not by our pages, and the retailer's own cookie banner governs them once you arrive. We see aggregate reporting from the networks, not your identity or browsing.

How to control cookies

When you first visit, our cookie banner lets you accept or reject non-essential cookies, with both choices equally available. You can change your choice at any time using the Cookie preferences link in the footer.

You can also control cookies in your browser: every major browser lets you view, block and delete cookies for any site, and clear local storage. Blocking strictly necessary cookies may stop parts of the site working properly. Your browser's help pages explain the controls, and the ICO's guidance at ico.org.uk explains your rights around online tracking.

Changes to this policy

If the cookies we use change, we will update this page and the date at the top, and where the change involves new non-essential cookies we will ask for your consent before setting them.
