Can you put two single mattresses on a double or king-size bed?

Because of their width, two single bed mattresses do not equate to a double or king-size and would not be suitable for a double or king-size bed. If you'd like to put two single mattresses together, you'll also need to buy two single bed frames.

Single Mattresses

Q: What size is a standard single mattress?

All standard single mattresses are 90cm wide by 190cm long, or 3' x 6'3". This makes a single size mattress ideal for solo sleepers or children. They work especially well in smaller rooms where space is at a premium, but are still large enough to allow a single person to fully relax.

Q: Are all single mattresses the same size?

Yes, all single mattresses are the same size. If you’re taller or heavier than the average person, or simply want more room to stretch out, you might want to go for a slighter larger and wider style. We have plenty more mattress sizes on offer, including small double, double, king, European king, and super king. You can learn more about the ideal size for your body type in our mattress size guide.
