{"product_id":"sprout-firmus","title":"Sprout Firmus 12-Inch Two-Sided Firm Natural Mattress","description":"\u003cp\u003eThe Firmus is the firm end of Sprout's three-mattress line, and the name is doing honest work. A queen holds 750 zoned pocket C-coils, double edge-guarded, with 14-gauge wire at the head and foot and heavier 13-gauge wire reserved for the lumbar zone alone. Coil gauge runs backwards from what you might expect: the lower the number, the thicker the steel. So the middle third of this bed pushes back hardest exactly where your body presses down most.\u003c\/p\u003e\n\n\u003cp\u003eThis is a true two-sided, tight-top mattress, the kind you flip and rotate the way mattresses were built to be. On each face, the comfort layers are wool, 100% Dunlop latex, and cotton under a herringbone 100% cotton cover. Hand-tufting with wool rosettes pulls those layers tight so they resist body impressions instead of collecting them.\u003c\/p\u003e\n\n\u003ch2\u003eWhy the badge on the side matters\u003c\/h2\u003e\n\u003cp\u003eSprout mattresses are handcrafted in Edmonton by Araam Inc. and endorsed by the \u003ca href=\"https:\/\/chiropractic.ca\/media-centre\/canadian-chiropractic-association-endorses-araam-inc-s-sprout-sleep-line-of-products\/\"\u003eCanadian Chiropractic Association\u003c\/a\u003e, which represents more than 8,000 licensed chiropractors.
