Buy the Purple Restore Hybrid Mattress.

It costs more, but it's the one still being made, still holding its shape, and still sleeping cool a decade from now.

What was compared

1. Sleeps cool while Casper traps heat
Purple's open GelFlex grid lets air pass straight through the mattress, while Casper's gel memory foam still holds body heat against the skin. For a hot sleeper, that's the difference between kicking the covers off at 2am and staying asleep.
2. Eases aches Casper owners report
The GelFlex grid cradles hips and shoulders for real spinal alignment, while Casper Wave owners describe new neck and back pain showing up within months of sleeping on it. If pressure relief is why you want a hybrid, this is the one that actually delivers it.
3. Holds its shape where Casper sinks
A 7-year Purple Restore owner reports zero dipping or sagging, while Casper Wave buyers describe deep body indents and fresh aches turning up within months. The 8 inch coil core and edge support foam are doing real work here, not just marketing copy.
4. You get a current model, not a retired one
The Casper Wave Hybrid has been discontinued and replaced by the Dream Max, so you're buying leftover stock of a bed the company already moved on from. The Purple Restore is the brand's current hybrid, backed by an active 10-year warranty.
5. Yes it costs more. Buy it anyway.
Casper's Wave Hybrid runs about $1,278 cheaper, but it's a discontinued model already drawing sag and ache complaints. Spread across a decade of nightly use, that gap works out to roughly $10 a month for better cooling and pressure relief that actually holds up.
