Wood type is not what determines what log beds are strongest. First there is the way the piece is constructed and whether the logs were properly dried and cured prior to being made into a bed.
The log beds offered at Log Furniture Place are designed and built to be stable, strong, and durable peices of furniture. Choose the wood type and design you like and enjoy decades of peaceful slumber in a bed you'll no doubt be passing onto the next generation in the future.
