Is the Roscoe good for everyday lounging?

It is an accent chair with a padded seat and backrest, so it suits reading and conversation. It has no recline or footrest, so it is not built for long naps.

Fabric or vegan leather: which should I pick?

Fabric breathes better and feels softer in warm rooms. Vegan leather wipes clean more easily but can feel warm and stiff, especially when new.

Will it fit in a small apartment?

It is a single-seat armchair, so it takes less floor space than a sofa or recliner. Measure the seat depth and the space behind it before placing it in a tight corner.

Does it match a sofa as a pair?

It works as a standalone accent chair or beside a sofa. Check the upholstery option against your sofa's fabric, since the chair comes in fabric or vegan leather.
