Does the Hector lift you to standing?

Yes. It has a power lift mechanism that raises the seat and tilts it forward to help you stand. The recline and lift run on separate motor functions.

Yes. Valencia uses Italian Nappa 11000 top-grain leather on the cover. That is a step above the bonded leather or fabric found on most lift chairs.

How much space does it need behind it?

It is 39.3 in deep, and the lift and recline need clearance behind the backrest. Leave several inches between the chair and the wall so it can fully recline and lift.

Does it have a massage function?

Yes. It has a built-in massage function, along with lumbar support. It is a vibration-style massage rather than a roller or shiatsu massager.

Do I have to assemble it?

Yes, assembly is required. The back and base typically need to be joined and the power connections made. Two people make it easier given the chair's size and weight.

Is it good for a media room?

It works well as a single leather recliner in a living room or media room. It has a USB port and side pockets, but it is a single chair, not a matched theater row.
