Is the Purple Restore Plus good for side sleepers?

Yes. The medium feel and GelFlex Grid are designed to cushion shoulders and hips, which suits side sleeping.

The grid top and cooling cover are built to let air move, and owners generally report it sleeps cooler than foam beds.

Do I need a box spring?

No foundation is included. It works on a platform bed or adjustable base; a box spring is optional.

It is listed as medium, with soft and firm options noted in the specs. Most shoppers should expect a medium feel.
