How many people and pets fit on it?

The maker says it holds three dogs, two children and two adults lying down at once. In practice that is a tight fit, and most households use it for one or two people.

Is the cover really machine washable?

Yes. The outer cover zips off and goes in the washing machine, and a separate inner cover protects the foam underneath.

Is the foam orthopedic?

The maker describes the foam as orthopedic and says it conforms to the body. It is softer and thinner than a mattress, so treat it as a lounger rather than a bed for every night.

Can I use it outdoors?

It is a floor bed for indoor use. The cover resists spills, but the foam should not be left outside in rain or damp.

How does it compare with a beanbag?

It has more structure: raised bolsters support the head and neck, and the foam base holds its shape better than loose filling. A beanbag is lighter and easier to move.
