Is this mattress a good choice for side sleepers?

Yes. It scores 8.7 out of 10 for pressure relief, with a deep contour that cushions a shoulder or hip without bottoming out. Three inches of conforming foam, an inch of memory over two of gel, spread load across the heaviest contact points while the 1000 pocketed coils flex one at a time underneath. At a medium 5 out of 10 it takes the sharp pressure out of side-sleeping zones yet keeps you supported on top of the coils.
