The short answer

How they feel: foam over coils vs the GelFlex Grid
The Helix Midnight layers gel memory foam and responsive foam over pocketed coils. It's a medium, about 6.5 out of 10 by independent testers, with a gentle contour and supportive spring underneath. It scores 4 out of 5 across edge support, motion isolation, cooling and pressure relief in our review-based ratings.
The Purple Mattress is all-foam with a 2-inch GelFlex Grid on top. It's a medium-firm, about 6 out of 10. The grid feels squishy under pressure points, then springs back, so there's no slow sink. It matches Helix on motion isolation, cooling and pressure relief (4 out of 5 each) but has weaker edges (3 vs 4). It's also slim at 9.25 inches, versus 11.5 for Helix.
Who should pick each: Purple vs Helix by sleeper
Pick Helix if you sleep on your side, want the support and edge strength of coils, or want a familiar memory foam feel at a lower price. Skip it if you dislike memory foam altogether.
Pick Purple if memory foam has felt too warm or too sticky for you, if you change positions often, or if you want something that feels different from a standard foam bed. Skip it if you need strong edges or want a tall mattress.
The second models matter here. The Helix Dawn is firm, about 7 out of 10, with reinforced edges, for back and stomach sleepers. The Purple Restore Hybrid puts the grid over 8-inch coils with stronger edges, but at around $2,399 on sale it's about twice the Midnight's price.
Value and policies: Helix costs less for the same terms
The Helix Midnight lists at about $1,478 and is often around $1,183 for a queen. The Purple Mattress lists at about $1,599, with periodic discounts. Both list a 100-night trial and 10-year limited warranty, though some reviewers cite longer Helix terms. With policies equal, Helix gives you coils for less money.

Which is firmer, Helix Midnight or Purple?
They're close. Independent testers rate the Helix Midnight about 6.5 out of 10 and the Purple Mattress about 6. The bigger difference is feel: Helix contours with memory foam over coils, while Purple's grid cushions and rebounds instantly. Back and stomach sleepers wanting firmer should look at the Helix Dawn.
Does Purple sleep cooler than Helix?
Not by much. Both score 4 out of 5 for cooling in our review-based ratings. Purple's grid has open channels for airflow, while the Helix Midnight's coils let air move through the mattress. If cooling is your top priority, the Purple Restore Hybrid combines both and carries a cooling-focused cover.
