They were easy enough to put together. We have XL deck pillows and they made the front bulge out which mean we couldn't just close the latch but we would also need to purchase a lock. Still doesn't take away from the fact that the plastic is not as sturdy as one would expect. We bought two and kept them at this point. We ordered a 230 gallon trunk. Hopefully that will do the trick for our large pillows. I guess sturdy enough to hold small or regular size items.
