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.
Springwall Foam mattresses provide all-foam comfort with excellent pressure relief and motion isolation. These Canadian-made mattresses use high-density foams (including eco-friendly BioFoam) to offer supportive, budget-friendly sleep solutions.
