Cheap single (twin in us) mattresses

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, this 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).

Cheap twin xl mattress deals

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

Rarely seen in the UK, the twin 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.

Cheap double (full-size in us) 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.

Cheap 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).

Cheap 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. 

Cheap super king (California king in us) 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.

WHEN Do the BOXING DAY 2018 sales start?

Boxing Day sales usually begin early (very early) on the 26th December, and is a day known for the biggest sales of the season. Ideal for spending all of that Christmas money...

Are Boxing Day sales mattress deals real?

Yes, but... since many products' prices change frequently, checking the price history of what you're buying on or PriceSpy will tell you whether the savings are real or not, and whether a price is likely to re-occur.

Is my new mattress the right size?

Before you buy in a rush, desperate to score that brilliant mattress deal, check you've got the size right. Here are the choices:

  • Single: 90cm x 190cm
  • Small double (often called a queen): 120cm x 190cm
  • Double: 135cm x 190cm
  • King: 150cm x 200cm
  • Super king: 180cm x 200cm

Will your mattress fit your bed frame?

Take care to compare the mattress widths and lengths with your bed measurements. For example, Ikea has European and UK standard sizes of beds from single to kingsize, with the standard UK sized frames differing dependant on design, so to be sure you may want to head over to their online guide.

Is the mattress right for you?

There are a few different types of materials used in mattresses, as well as hybrid options that include latex or gel, but the two most common types are memory foam and pocket sprung.

What about mattress firmness? Mattresses range from soft medium; medium; medium firm; to firm and extra firm.
