King Reflexion® All
King mattresses measure 76" × 80" — the widest standard size, giving each partner the same personal space as a twin. They're the top choice for couples who want maximum room, families who co-sleep, and larger master bedrooms. Compare every king option below by brand, feel, and price.
Sealy® Reflexion® adjustable bases turn a flat mattress into a bed that moves with you — head and foot articulation from fully flat to upright, driven by a wireless remote. The collection runs two models. Boost is the accessible entry: a foldable, zero-clearance frame light enough to carry between rooms and slim enough for narrow doorways and staircases, rated to 650 lb, with One-Touch Flat and a reprogrammable Favorite. Arc adds dual-zone head and foot massage at two intensity levels, the signature IdealArc sitting position with Wall Glide, Zero-Gravity and TV presets, under-bed LED lighting and USB-A/USB-C charging, rated to 850 lb in every size. Both carry a 25-year warranty and ship with free Canada-wide delivery.
