The Bed Rail range is available in three colours to compliment any bedroom interior as well as four sizes, to ensure all bed types can be safely secured for a good night's sleep for your little one. When selecting a bed guard it is important to leave a gap of 25cm between each end of the bed and corresponding end of bed rail, as well as ensure the top of the bed guard will protrude at least 16cm from the top of the mattress. The bed guard features a fold down mechanism which allows parents easy access to their child, and an easy way to lift a sleeping child into bed. The mesh bed rail range is compatible with a sunken mattress and solid and slatted beds. The bed guards require assembly and the assembly video is available for your use on this listing. The bed guards comes complete with a useful carry case, should you want to take it with you on your travels. Each of the bed guards can be purchased in pairs to be used on either side of the bed if required. The four available sizes are as follows (Please note the typical bed suggestions are a guide only, and it is strongly recommended to measure your mattress size first before purchasing the correct size bed guard): 90cm(W) x 40cm(H) (Typically used on cot bed mattresses with measurements of approximately 70cm x 140cm) 110cm(W) x 40cm(H) (Typically used on large cot bed or small single bed mattresses of approximate length of 150cm - 180cm) 140cm(W) x 50cm (Typically used on single mattresses with measurements of approximately 90cm x 190cm, or queen sized mattresses with measurements of approximately120cm x 190cm) 140cm(W) x 60cm(H) (Typically used on double bed mattresses with measurements of approximately 135cm x 190cm and King size beds with measurements of approximately 150cm x 200cm)
