Classically designed, the Berlin Fabric Ottoman, covered in stylish fabric, adds both style and versatility to any space. With strong gas-lifts to access the storage space, this frame is available upholstered in steel, black crushed velvet and grey polyester. The Berlin Fabric Ottoman frame now includes a protective base sheet. With a sprung slatted base for natural bounce, the frame adjusts to where pressure is exerted most, providing greater comfort. The gas piston strength on this frame is 600 N and can support mattresses up to the weight of 45 kg. The maximum weight load for the 3' frame is 150 kg, all other frames are 200 kg. Please note the mattress needs to be on the bed for the pistons to work. Birlea beds are only suitable for a UK standard size mattress and the recommended maximum mattress height is 250 mm.
