A perfect fit for all Boori cot-beds, the Boori traditional coil sprung mattress is built to the highest standards with heavy duty fabrics and springs so they remain suitable for growing children year after year. Mattresses are vented to prevent moisture build up: Quilted air permeable fabric cover on one side and a hygienic wipe clean cover on the reverse. Waterproof nappy protector adjusts as baby grows allowing baby to be placed at the foot end of the cot. The removable cover is hand washable and may be put through a short spin but must not be tumble dried. Included in the price of all cot-beds but also available to buy as a spare. Our mattresses are made in the UK to British Standards. They meet British Standard BS 1877: Part 10: 1997 and BS 7177. Mattresses are excluded from our 5 year warranty. Mattress dimensions: 1310L x 750W x 100H Notes: Upon purchase, the waterproof nappy protector is situated under the outer cover of the mattress. Parents wishing to place baby feet to foot end, should unzip the cover and move to the foot end of the mattress. As baby grows the protector should be moved up the mattress in line with baby's nappy area, thus aiding hygiene. The cover on this mattress is filled with pure new wool.
