Another large mattress was built by Dolidol Maroc and its a 52.5′ (16 m) x 65.6 (20 m) monster. The World Record Academy claims this to be the biggest bed in the world. It is 4.6′ (1.4 m) tall and weighs 11 tons.

The Family Bed measures 84” x 144” x 13” (7′ x 12′ x 1.1′) for a staggering 12,096 square inches or 84 square feet!!! I have lived i seen rooms smaller than this! Ok, it was in a truck while away working for six months.

This is the equivalent of 3.1 regulation pool tables and 2.5 queen size. That puts it into perspective.

And if you are interested, that is 157,248 cubic inches or 91 cubic feet.

Personally, I would rather sleep on a cheap cot and invest the money, go on a trip, or buy many beer.

The double platform frame is sold separately and is the same size as the mattress, so the “mattress” and the “bed” are the same.

You can see more information or purchase this giant on The Bedding Mart here.

To buy in a store they have locations in Arkansas, Missouri, and Texas.

Honorable Mention: The Ace Family at 80” x 144” is only four inches shorter than The Family Bed

Honorable Mention: Alaska King at 9′ x 9′ for 81 square feet. As you can probably guess you won’t find this in every store that sells mattresses.

Biggest Size in US Widely Available in Stores

The biggest size in the US that is sold in most online and brick-and-mortar stores is the King size. The standard dimensions are 80” (6.7′) long and 76” (6.3′) wide, which is 42.2 square feet.

This is slightly smaller and less common California King is 84” (7′) x 72” (6′) for 42 square feet.

Biggest in the UK

The Big Bed Company in Denham, England offers their products in custom sizes up to the biggest size in the UK, the Bespoke at 10′ x 10′ (305 x 305 cm) for a total of 100 square feet.

This is only available at one store location and it may be considered cheating as they put two mattresses together and they are zipped together when installed on the frame.

Biggest in Canada

The Mattress and Sleep Company offers the Super King Mattress and it is a moose at 85.5” (7.1′) x 84.5” (7) or 217 x 215 cm. This is a total of 49.7 square feet.

Canada has the same standard options as the US so the King information is the same.

For 9 sizes and models bigger than a king please see my information here, average bed dimensions in feet for each mattress size, if yours is too big for your mattress fix it easy with these tips, and check average bedroom sizes to help match your bed size here.
