The simplicity of this Height Adjustable Bed Cradle is also the key to its reliability and durability.It has a tubular metal frame with a lower section that slips easily under the mattress to keep it firmly in place. The upper section cantilevers out to provide an effective support for bed covers, blankets or duvets. An easy to use height adjustable system on the side of the blanket cradle allows the user to alter the clearance for comfort. The cradle spilts easily in to two sections for easy storage when not required.
