Does every seat recline with power?

Yes. The set is sold as a power recliner set, so each of the three seats has motorized recline rather than a manual lever.

How much wall clearance does it need?

Power recliners usually need several inches behind the backrest to recline fully. Leave room behind the set and check the recline depth before placing it against a wall.

Does it need to be plugged in?

Yes. Power reclining seats run on electricity, so you need outlets within reach of the set, and a power strip or extension may be needed for three seats.

Is it a sofa or separate cinema seats?

It is listed as a cinema sofa set of three pieces with armrests. Expect theater-style connected seating rather than a standard three-seat couch.

What is included in the set?

The set is three reclining pieces. Confirm with the seller whether the pieces are joined or separate and whether any cables or power supplies are included.
