Price-performance ratio. Previously had the same, only had bigger and was well pleased. Of course there are better adjustable bed bases, but also cost the same a few more hundreds and where you can find mE hardly or only minimal differences. Of course you have also a good mattress to bad because mattresses are extremely quickly and then the slatted frame can cost what they want, you will always have problems. I am of the opinion, a good mattress and the bed base are a good combination. Delivery to notice on time - everything was great.
