Is this a complete adjustable base?

No. It is Box B, one of two cartons for the queen base. You need Box A as well to assemble a working base.

Box B holds part of the queen base frame and its fittings. The rest of the base, including the motors and remote, ships in Box A.

Will it fit a standard queen mattress?

Yes. It is built for queen-size mattresses and standard queen bed frames.

It is made to pair with Box A of the same Comfort Ultra queen model. Check the model name on your existing box before ordering.

Plan on two. A queen adjustable frame is heavy and awkward to handle alone.

The remote and power components are in Box A, not Box B.
