Which is better for side sleepers?

The Sealy is labeled for side sleepers and its medium tight top gives a little more give at the shoulder. The Nectar Premier is medium firm, so heavier side sleepers may prefer it and lighter ones may find it firm.

The Nectar Premier. Its cover has PCM and over 60% more cooling fibers than Nectar Classic. The Sealy has a MoistureProtect cover but no active cooling layer.

Which has better edge support?

The Sealy. Its Coil Edge is built for a solid, durable edge. The Nectar Premier has coil edge support but no reinforced perimeter claim.

Is the box spring included?

Only with the Sealy set, which includes a standard-profile box spring when that option is selected. The Nectar Premier is mattress only.

Is the Nectar Premier worth about $11 more?

If you want cooling and more pressure-relieving foam, yes. If you want an innerspring feel and a box spring in the price, the Sealy set is the better buy.

Both use CertiPUR-US foams and encased coils, so lifespan depends on weight and base. The Sealy's coil edge may hold shape better at the sides; the Nectar's thicker foam layers may soften sooner.
