Good point. I hadn't considered that. I figure it'll weigh around 500
kg alltogether. The surface area is 150 x 70 cm = 1,2 m2. That's 416
kg/m2. The floor is made out of concrete, and I'm putting it into a
corner of two load-bearing walls. I'll make a call to the housing
corporation to find out what the maximum load is.
