When designing with children, you have to think from the floor up. If you have infants or toddlers, then looking for sharp corners is a good place to start. When you can, go for round shapes. This especially applies to coffee tables. They’re just the right height for little ones to run into, so a round coffee table will help you avoid many bumps and bruises. If your little ones love to climb on the sofa, then you might also want to consider kid-height ottomans for extra seating and play surfaces.
