This bed with storage will be delivered to you in two or three boxes. You'll need to attach the pieces together using the instructions and fitting provided. We'd recommend two people to put the bed together. Once you have put the bed together, pop your mattress on then try lifting up the ottoman, we recommend you don't try it without the mattress. Unlike some ottoman beds on the market we have increased the weight bearing of our gas lift mechanisms to make it easier for you to lift your ottoman up and down. The first few time of using the ottoman may appear stiff, however, this will loosen up over time.
