Lakeland Underbed Plastic Storage Box On Wheels 50L 2 "Adrien" Mrs Willcocks 09 March 2015 7/3/15 Adequate, just, if you only need to store very light objects. Books would be too heavy and the bottom would sag and drag on the floor as there is very little clearance and the wheels are only 8mm width so if these are on a carpet they sink in and make lines in the carpet. I have cut out a piece of triple wall polycarbonate sheeting which is 15mm thick and very light and placed on the inside bottom of the drawer. This gives strength to the floor and avoids the drawer bottom sagging and therefore dragging on the floor. If I buy any more I would look for something better. A note from the team Thanks for the feedback and taking the time to speak to me on the phone, I'll be sure to pass on your suggestions about the wheels and the base to our buying team.
