What size is a double mattress?

A double mattress measures 4 feet 6 inches wide (135cm) and 6 feet 3 inches long (190cm). They are designed to sleep two people comfortably, but can also be used by individuals who are looking to stretch out a bit more in bed. Our double mattresses come in a variety of different depths and weights depending on the type of mattress you choose.

Are all double mattresses the same size?

The length and width of a double mattress is consistent across all brands / types of double mattress, however the depth of the mattress may differ. It is also possible to purchase a small double mattress which is slightly narrower as 4ft wide compared to a double mattress being 4ft 6 wide.

Will a double mattress fit a small double bed?

While a double mattress will fit on a small double bed frame or divan, the mattress will stick out by 3 inches each side of the frame as a double mattress is 6 inches wider than a small double mattress / bed. For the ultimate comfort, it is recommended that you use the correct bed size with your chosen mattress.

How many springs should a double mattress have?

The number of pocket springs used in a pocket sprung double mattress will vary depending on the brand, quality and design of the mattress, however it is recommended that double mattresses have a bare minimum of 600 pocket springs. All of our pocket sprung double mattresses contain a minimum of 1,000 pocket springs, with our higher end ranges containing up to 35,000 pocket springs.

How much does a double mattress cost?

The price of your double mattress will vary depending on the comfort level, quality, materials used and more. At Sussex Beds, our double mattresses start at around £229.99.
