The Helix Plus Luxe Medium mattress is engineered for plus-size sleepers and anyone who needs maximum durability with a supportive, medium-firm feel. A heavy-duty TitanCore coil system, high-density foams, and a zoned ErgoAlign layer deliver industrial-strength support, edge reinforcement, and spinal alignment for all sleep positions. A plush, hotel-style pillow top with a GlacioTex cover and CoolForce cooling layer provides over 12 hours of cool comfort, and a removable, machine-washable cover makes care easy.
