Bought for my balcony to store gardening supplies. Fits a large bag of soil, plant food, watering can, and still has room for some other items. So far everything has stayed dry which is all I can ask for. I do not have any plans to sit on it or use as a seat, so I can’t say how it will hold up in that aspect. It was simple to assemble, just slotting plastic pieces together. No hardware necessary.
