Best single or twin mattress deals

US: Twin mattress dimensions: 39-inch x 75-inch. Depth varies.
UK: Single mattress size: 90cm x 190cm approx. Depth varies.

Despite the twin name, the twin mattress is the smallest mattress size found outside of baby cots and cribs. Generally used in children's rooms or in smaller living spaces like studio apartments for adults, if you're tall, it's worth noting that they're only 75 inches in length (US).

Best twin mattress deals (xl)

US: Twin mattress dimensions (XL): 39-inch x 80-inch. Depth varies.

Rarely seen in the UK, the twin mattress XL isn't actually that much bigger than a twin mattress: it's five inches longer but the same width. Ideal if you're limited on space or have a teenager at home who won't stop growing.

Best double or full-size mattress deals

US: Full-sized mattress dimensions: 54-inch x 75-inch. Depth varies.
UK: Double mattress size: 135cm x 190cm approx. Depth varies.

The double mattress, also known as a full-size in the US, is a good option for your first bed big enough for two. It's 54 inches wide so if you or your partner are prone to moving around much during sleep it might be worth considering something larger. Smaller apartments or guest rooms might be a better match with this size.

Best queen size mattress deals

US: Queen size mattress dimensions: 60-inch x 80-inch. Depth varies.

Not often seen in the UK, Queen mattress deals are the most in-demand of all bed sizes in the US thanks to their happy medium of decent size and low cost. Both wider and longer than the full-sized double mattresses, a queen is the one most people go for if their room can accommodate a bed of this size (at least 10ft x 10ft).

Best king size mattress deals

US: King-sized mattress dimensions: 76-inch x 80-inch. Depth varies.
UK: King-size mattress size: 152cm x 198cm approx. Depth varies.

For professional sprawlers or families with young children who like to hop in bed with their parents some nights or early mornings, as far as bedroom sizes go, you'll be needing a room measuring around 12ft x 10ft. More often than not, this is the biggest size most manufacturers do for mattresses. 

Best super king or California king mattress deals

US: California king mattress dimensions: 72-inch x 84-inch. Depth varies.
UK: Super king mattress size: 180cm x 200cm

The biggest size available in the USA, the California king mattress is oddly enough actually four inches less wide than the king but four inches longer. Perfect for taller people and those with invading kids or a sleeping dog at the end of the bed.

Mattress topper deals

It's a smart idea, that if you're buying a new mattress, to also buy a topper with it. Not only does a mattress topper supplement the comfort of your mattress, but it can also add support to a mattress that may be too soft or firm for your liking.

Read our best mattress toppers guide or see below for the best ones and their cheapest prices.

Mattress protector deals

Along with your new mattress purchase, you're going to want to add a mattress protector to your basket, too. After all, there's no point in forking out lots of money on an expensive, luxury mattress if you're not going to protect it, right? A mattress protector is an item of removable bedding which simply just sits on top of your mattress to protect it from spillages or stains and also allergens and irritants like bed bugs, mould or dead skin.
