An OKA best-seller and customer favourite, our double standard mattress is perfect for guest bedrooms and children's bedrooms. This pocket-sprung mattress is spring to medium firmness, offering excellent support. Featuring a high spring count - the double mattress has approximately 1,100 springs - with two rows of firmer springs around the edge for extra support and stability, it is covered in the finest quality 100% cotton ticking, sourced from traditional cotton mills. A double divan bed base is available to buy separately, either with or without drawers. To keep your mattress in premium condition, rotate the mattress 180 ° after 3-4 weeks so the head becomes the foot, then 3-4 weeks later, flip the mattress so the bottom becomes the top. Repeat this cycle every 3-4 weeks.
