How does the 3 in 1 conversion work?

The backrest adjusts through three positions: upright for sitting, angled for lounging and flat for sleeping. You change positions by hand; there is no pull-out frame.

Is it comfortable enough to sleep on every night?

It is built for occasional use. The cushioning is thinner than a real mattress, so most people use it for guests or naps rather than as a main bed.

How big is the sleeping surface?

The sofa is 34 inches deep and 34 inches high. When laid flat, the sleeping length is close to the sofa's width, so check your room and your height before buying.

Does it come with pillows or a mattress topper?

No. The sofa is the only item; bedding, pillows and toppers are bought separately.

It is upholstered in fabric over a padded frame, in gray. The fabric cover is not described as removable.

How does it compare with a pull-out sofa bed?

It is lighter and simpler, with no metal mechanism to break. A pull-out sleeper gives a thicker mattress and a longer bed, but takes more floor space and weighs more.
