How they feel: Casper's foam vs Purple's grid
Casper The One is an 11-inch all-foam bed with open-cell Breathe Flex foam over Align+ memory foam. Independent testers rate it about 7 out of 10, a medium-firm that leans firm, with a gentle contour and very little bounce. Its standout trait is motion isolation, a 5 out of 5 in our review-based ratings.
The Purple Mattress is softer, around 6 out of 10, and feels unique. Its 2-inch GelFlex Grid buckles under pressure points and springs back immediately, so you float rather than sink. It scores higher than Casper for cooling (4 vs 3 out of 5) and bounce, and both earn a 4 out of 5 for pressure relief. Edges are average on both.
Who should pick each: Purple vs Casper for your sleep style
Pick Casper if you sleep mostly on your back or switch between back and side, if a partner's movement bothers you, or if you prefer a classic memory foam feel at a lower price. Skip it if you sleep hot or are a light side sleeper who needs more give at the shoulders.
Pick Purple if you sleep on your side, run warm, or change positions often and want a surface that doesn't fight you. Skip it if you want a firm, flat bed for stomach sleeping, or if the grid's squishy texture sounds odd to you. Purple is also slim at 9.25 inches, which matters if you like a tall bed.
If you want Purple's grid with coil support and stronger edges, the Purple Restore Hybrid is the upgrade, but at around $2,399 on sale it costs more than twice as much as Casper The One.
Value and policies: price, trial and warranty
Casper The One lists at about $1,149 for a queen and is often around $899 on sale. Purple lists at about $1,599, with periodic discounts. Policies are identical: a 100-night trial and a 10-year limited warranty from each. That makes Casper the better value unless Purple's feel or cooling is what you're after.
