What size bed does the floor sofa make? Queen or king?

Also asked as:What size bed is this equivalent to?What are the measurements side by side on the floor?

Two mattresses, one floor. The math is simple. A whole room that turns into a bed is a different feeling.

Two floor sofas meet in the corner to make an L-shaped lounge, one edged in rust and one in mustard.

The quick answer

The floor sofa makes a bed of about 79 x 79 in (200 x 200 cm), roughly king size. Each seat mattress is 39 x 79 in (100 x 200 cm), about a US twin XL, and two side by side give that square. The corner version with ottoman lays out larger than a king, and the teddy convertible opens to 63 x 78.7 in (160 x 200 cm).

Each seat mattress is 39 x 79 in. That is close to a US twin XL. Two of them, side by side, make a square of about 79 x 79 in. One careful measurement came back at 78.5 x 78 in. Fabric and filling move a little.

The workshop has called this layout both double and king. By the numbers, it is roughly king. The bed size and firmness Pattern goes further.

On a tatami platform, and in a small room

A buyer in the US planned to set the sofa on a king-size tatami platform. The seat cushions side by side come to roughly king-bed size, so it suits.

The corner version with the ottoman lays out larger than a king. It needs that floor free. Leave a hand's width of floor around it if you can. The layouts Pattern and modular floor sofas show the shapes. Will it be a sofa most nights, or a bed?

A sofa by day. A bed by night. The same 79 inches.

The floor sofa corner set with ottoman lays out larger than a king bed, with room for 2 adults and 2 children on the floor.
