For side sleepers over 230 pounds, yes — they rated it 9.5/10, the best fit result on either Nectar hybrid. For nearly everyone else the case is thin. Measured by the same lab on the same scale, stepping up from the Classic Hybrid gains half a point in pressure relief, motion isolation, and materials durability, but loses half a point in cooling and ease of movement, and a full point in edge support. Firmness is identical at 7/10, and the coil unit underneath is literally the same component. The Premier Hybrid is a good mattress; it is just a lateral move dressed as an upgrade unless you are a heavier side sleeper.
