Sometimes, it's easy to be side-tracked by an attractive price tag - but how do you know you're getting good value?

It's essential to make sure you're not missing out on some important fine print, so double-check the following when buying a cheap mattress:

• Ensure you're choosing a quality mattress with quality fillings. This means choosing a memory foam mattress with a high density or a pocket-sprung mattress with a high pocket spring count.
• Double-check the mattress sizes. Not all mattresses are available in larger king or super king sizes, and sometimes a mattress only seems cheap if you're looking at small single or small double sizes.
• Confirm if your discount is automatically applied or if you need a specific code to enter at checkout.
• If applying an additional discount, ensure it doesn't only apply to full-price mattresses - i.e. sometimes additional discounts can't be applied to already discounted products (all our exclusive discounts can be applied even if the item is already discounted).
• If the deal you're getting includes a freebie, check the price of the freebie to see how much you're saving. Also, consider if the item is something you actually need, otherwise it might not be a great deal.
• Ensure your mattress comes with fast and free delivery.
• Always make sure the mattress you choose comes with a risk-free sleep trial period.
• It's good to check if the mattress brand you've chosen offers an old mattress removal service if that's relevant to you.
• Check the warranty conditions - a good mattress will come with a minimum 5-year guarantee.

Browsing the internet for a range of mattresses can be overwhelming.

That’s why all the best mattress offers we recommend are from trustworthy brands.

Many of these are mattresses with a medium-firm feel, perfect for orthopaedic support and a range of sleepers, and with great pressure-relieving properties.

Our top-recommended brands also come with a minimum of a 100-night trial, free delivery, and a 10-year guarantee so you can rest easy.
