Which is better for side sleepers?

The Helix Midnight Luxe. It is built for side sleepers, with memory foam at the hips and shoulders and zoned coils that are softer under the shoulders and firmer under the hips. The Sealy is a plain medium Euro pillowtop with no zoned support.

Is the Helix worth about twice the price?

If you value the 365-night trial, lifetime warranty and denser foam, yes. At $1,194.00 versus $582.30, you pay about $612 more. If you just need a medium queen set with a boxspring, the Sealy covers that for less.

The Helix has the stronger durability case: a limited lifetime warranty, 4 lb high-density foam and up to 1,000 individually wrapped coils. The Sealy lists a reinforced Coil Edge but no warranty terms, so its lifespan is less certain.

Do both come with a boxspring?

Only the Sealy. The Seafield is sold as a set with a boxspring. The Helix Midnight Luxe ships as the mattress alone, so add a foundation or adjustable base if you need one.

The Helix, especially with the GlacioTex cooling cover upgrade; the standard TENCEL cover is breathable too. The Sealy relies on Surface-Guard and MoistureProtect treatments rather than a cooling cover.

Can I try either one before committing?

The Helix comes with a 365-night sleep trial. The Sealy listing shows no trial, so check the store's return policy before ordering.
