What mattress thickness does this Murphy bed need?

Wall-bed cabinets of this type usually take a mattress around 8 to 10 inches thick. A thicker pillow-top can stop the bed folding flush and strain the mechanism. Check the cabinet's internal depth before buying a mattress.

Can it be mounted on drywall?

No. A queen Murphy bed and its cabinet are heavy, so the frame must be fixed to wall studs or masonry. Drywall anchors alone will not hold it. Hire a carpenter if you are unsure about the wall.

Does it include the mattress?

No. The listing covers the bed and cabinet; the mattress is sold separately. Budget for a thin queen mattress that fits the folding depth.

How does it compare with a metal Murphy bed kit?

Metal kits are lighter and cheaper to ship, but they leave the bed visible when folded. This pine cabinet hides the bed and adds storage, at the cost of more weight and a longer install.

Is it good for a rental apartment?

Only if your lease allows wall drilling. The frame bolts into studs and leaves holes when removed. For rentals, a freestanding folding bed or a sofa bed is the safer choice.
