FAQ

Is a twin and a double bed the same?

Despite its name, the twin bed by itself isn't for two fully-grown people, but on its own is the same size as either a small single or regular single bed. The term "twin bed" comes from the fact that two single beds can be pushed together and make up a bed the same size as a double bed. Thus, both the twin beds and the double beds are not the same - but will be the same size if you have two (twin) single beds.

Is queen bed bigger than king size?

The queen-sized bed is not bigger than the king-sized bed. It can sometimes be tricky to understand the differences between these two beds, with a lot of people seeing them as being equal to each other, or as an interchangeable word. This is not the case for UK bed sizes. A queen-sized bed is actually the same size as a small double bed, thus buying this bed and expecting it to be as big or if not bigger as a king size may just arise a few problems!

What's the biggest bed size?

The biggest most well-known bed size that many retailers, including Frances Hunt, offer is the super kingsized bed. There are, however, bigger beds in the form of eastern king, emperor and the caesar bed which measures a strong 245cm x 220cm! If you're looking for something more custom, be sure to contact us and we'll be happy to see what we can do.

Do two twins make a queen?

Two twin beds do not make a queen bed with bed sizes in the UK, as a queen bed is not that much bigger than one 'twin' or a single bed. Two twin beds would make up a double bed.

Which bed size is the smallest?

The smallest bed size is a small single bed, but other than that, particular beds for toddlers and babies do exist and they will be much, much more significantly smaller. These may not always feature a mattress as such, but will be somewhere of which a small child can sleep upon. A lot of parents opt to get a child a single bed as their first bed, as it allows the child to grow into it.
