The single-sided Durus is the medium-firm option in Sprout's single-sided trio, position four on the brand's official comfort scale. Sprout describes it as slightly firmer than the two-sided Durus, with enhanced support and durability, which makes it the all-positions pick for anyone who wants the CCA-endorsed line without the flipping routine. A queen runs $4,050, well under the $5,732 of the two-sided build, because the natural comfort layers are finished on one face rather than two. Care is rotation only. Handcrafted in Edmonton by Araam, from the only mattress brand the Canadian Chiropractic Association endorses as of mid-2026. Size 2026 MSRP Single $2,773 Single XL $2,813 Double $3,853 Queen $4,050 King $4,901 The Sprout line is built from natural materials over pocket coils and carries a 10-year warranty on a proper foundation; the low-profile box works well where overall bed height matters. Bracketing it in the single-sided range are the firm Firmus and the soft Somnus, and the full Sprout collection shows both builds side by side.
