So off to the Internet on Amazon and lo and behold, there are companies offering good quality at a reasonable price.
The company Ravensberger was not yet known by then.
Did then ordered these slatted and equal to a mattress.
The ordered goods arrived in a very short time with me. Other Furnitures need for 4 weeks!
Unwrapped off to bed and tested ...... TIP TOP!
I can only recommend this slatted frame! Thumbs Up and full 5 stars
