Mattress Guide

Did you know that we spend over a third of our lives in bed? That’s longer than we spend sitting on the sofa, sat in our favourite chair or in our cars. But we pay surprisingly little attention to the mattress that we will spend so much time lying on. A good mattress should support our bodies perfectly in the utmost comfort so we wake up refreshed and ready to face the day. As we all have different sleeping needs, choosing the right mattress for you should be the top priority; this guide will help you do just that.

Size does matter

The first decision to make is the size of your mattress; generally most people tend to make a split decision between a single or a double. But we recommend factoring in a few more considerations, for example a mattress should be a least 10cm longer than the height of the tallest person sleeping on it. You should easily be able to put both your hands under your head without your elbows touching the edge of the mattress or the person sleeping next to you. You also need to be aware that a UK mattress size can often be different from a European mattress, as the sizes differ.

What is the perfect mattress size for you?


70 x 140 cm

A toddler sized mattress will be perfect for kids aged between one and three and is a great starter for kids ready to move out of their cots. Care should be taken to ensure that the mattress fits perfectly in your kids' bed. Turning the mattress regularly will also reduce wear over time.

2'6 Small Single

75 x 190 cm

A small single sized mattress is also a good choice for toddlers and younger kids, they will fit narrower kids' bed frames and guest beds. A small single mattress is also a great choice if space is an issue, and is a good option for a spare room as they can be easily moved and are perfect for guests and visitors.

3'0 Single

90 x 190 cm

A standard single mattress measures 3ft x 6’3”; 36” x 75” (90 x 190 cm). This size is great for people who sleep on their own and is a good longer term option for a child as it will last well into their teens. Single sized mattresses are also an option for larger spare rooms and guest bedrooms.

3'0 European Single

90 x 200 cm

If you've bought a single bed from a European store, you would have probably noticed that European sized beds are a little bit longer than UK ones. Don't worry, at Dreams we stock European sizes, so just measure your bed to make sure you know exactly what size you need.

4'0 Small Double

120 x 190 cm

If you’re an average sized adult who doesn't mind sleeping close to your partner or a single sleeper who likes plenty of space, then a small double mattress is a great choice. A small double is also a good choice for couples whose bedroom isn't particularly wide.

4'6 Double

135 x 190 cm

A double mattress is the perfect sleeping solution for couples. This size allows for a good amount of room so each person can get an undisturbed night's sleep. Dreams stock a huge range of double mattresses with a wide variety of materials and construction.

5'0 King

150 x 200 cm

Great if you like plenty of sleeping room; a king size mattress will mean you'll be able to turn and move positions without disturbing your partner. If you or your partner are 190cm or taller we recommend a King. In the US this mattress is normally know as a 'Queen' and in Japan it's referred to as a 'Wide Double'.

6'0 Super King

180 x 200 cm

The very best in sleeping comfort - the super king mattress gives an unbeatable amount of space for you and your partner. And if you're a family who all like to squeeze in together on Sunday mornings or just someone who likes a lot of space, the Super King is a great option.

Did you know...

... the term “sleep tight” dates back to Tudor times, when beds were a wooden frame with a latticework of rope or leather to support the mattress. Occasionally these ropes of leather straps would slack and have to be tightened to prevent the mattress from falling on the floor.
