Ready to upgrade? Check current price on the Sealy Hybrid Bed in a Box—our top-rated alternative with superior cooling.
Rated medium-firm (7/10), the Flexgrid suits 70% of testers: back sleepers loved the lumbar reinforcement (minimal spinal alignment deviation of 0.5 inches), while side sleepers noted adequate shoulder relief up to 180 lbs. Heavier users (250+ lbs) appreciated coil durability, with only 4% sagging after 1,000 cycles.
Fair rating (62/100): Coils aid ventilation, but foam layers retain some heat (surface temp rise of 4°F after 30 mins). Compare to our Quick Pick's CopperChill tech, which drops 2°F faster.
Owner data from 10,000+ surveys shows 82% satisfaction for sleep quality, though 15% cited setup off-gassing (dissipates in 48 hours).
