Frequently Asked Questions About King Size Murphy Beds
What ceiling height do I need?
For vertical King and California King beds, you’ll need ceiling height at least 3–4 inches taller than the finished cabinet height.
How difficult is assembly for a King Murphy bed?
Even with the larger size, the build process follows the same steps as smaller beds. The kit includes high-strength pistons and hardware to support the larger frame safely.
What mattress sizes work with these Murphy beds?
Our King Murphy Bed fits a 76″ × 80″ mattress, and the California King fits a 72″ × 84″ mattress. Any type of mattress works as long as it’s 12 inches or less in height and falls within the specified weight, keeping your bed easy to lift and use.
How heavy should my mattress be?
For smooth operation, we suggest a mattress weighing 50-85 lbs. Too heavy, and lifting the bed can be tricky; too light, and the bed frame might float when it’s open. Finding the right balance makes using your Murphy bed effortless.
