Is this a true four-seater?

Yes. It is a four-seat sectional with an L-shaped chaise section, so it seats four along the main run plus the corner.

Which side is the chaise on?

The listing does not specify a left- or right-hand chaise. Check the chaise side against your room before ordering, since an L-shaped sofa cannot be flipped.

What is it upholstered in?

The cover is described only as black. The listing does not name the fabric or leather, so confirm the material and its care instructions before buying.

Will it fit through a standard door?

Sectionals usually ship in sections, but the listing gives no dimensions. Measure doorways and the room corner against the sofa's footprint before ordering.

How does it compare with a straight four-seater?

The L-shape adds a chaise and uses corner space, so it seats the same four people in a smaller wall run. A straight sofa is easier to move and rearrange.
