- Bouncy + responsive
Cons

- Heavy

3.Sleep Quality: Saatva's Hybrid Wins For Side+Back Combo Sleepers
Tracked via Oura Ring over 4 weeks per mattress. Saatva delivered the highest average deep sleep minutes (87 min) and lowest restlessness score. Casper had the best HRV recovery but worst temp regulation. Purple was middle of the pack on sleep metrics but reported the lowest morning back pain (2.1/10 vs Saatva's 2.4).
"I stopped waking up at 3am. That's it. That's the whole review."
4.Temperature: Purple's Grid Genuinely Sleeps Cool
Temperature sensor placed between sheet and mattress for 8-hour periods. Purple peaked at 89°F; Saatva 92°F; Helix 93°F; Casper 96°F. For hot sleepers in warm climates, Purple is the call. For everyone else, Saatva's hybrid runs cool enough.
5.Edge Support: Saatva Owns The Side Of The Bed
Sat on the edge of each mattress with a 30-lb dumbbell. Saatva compressed 0.8 inches; Helix 1.2; Purple 1.5; Casper 2.4. Matters if you sit on the bed to dress, or sleep with a partner who likes the edge.
6.Price: Cost Per Night (10-Year Lifespan)
All four are warrantied 10+ years. Real-world cost per night: Casper $0.35, Saatva $0.41, Purple $0.41, Helix $0.41. Saatva is the most expensive to buy and tied for cheapest per night of quality sleep.
7.The Winner: Saatva Classic
After 700+ tracked hours across 9 mattresses, the Saatva Classic is the clear winner. Saatva wins on build quality, support, and trial generosity. Casper if you want a bed-in-a-box under $1,300; Purple for heat sleepers; Helix for couples splitting the difference.
"A great mattress is the most leveraged purchase in your home. You'll spend a third of the next decade on it. The Saatva earned the role."
