We bought one of the high end king size beds with all the extras including frame and 'make the bed package'. The model was 'Coventry'.
It took a little longer than expected to actually get the bed installed (6 weeks)
The install was quick and friendly but communication could have been better. They asked us if we had floor savers for the bottom of the bed upon arrival. We immediately went out and bought some but they had already installed some they had with them. They took the ones we bought in exchange. We weren't asked what side we wanted the 2 different firmness installed on, until after it was complete. This can be changed by us with unzipping and shuffling of layers.
Everything is great except the pillows. They did not seem as soft and comfy as the ones we tried in the store. We returned them and were told we had to keep them, but that we could take some of the stuffing out to achieve the same comfort quality. The in-store after sales friendliness dropped off significantly.
Great product but it is pricey. The service is not up to Miele standards, but it shouldn't put you off if you value a really nice, high quality and healthy bed. A huge advantage is that a King size can be installed almost anywhere, as it comes in rolled up layers. A traditional king mattress would never have fit up our 3rd floor staircase.
