A worthy winner!

We (58 kg w. And 90 kg · m.) Have long considered and tested a variety of mattress for a double bed with 90 x 200 cm. We were in Concord, the Danish Bettenlager, the mattresses MFO in XXL etc. When sample chairs we always had to find that it is good for our demanding back products are not there to buy less than 400 or 500 euros! The reasonable promotions of Karstadt could both of us lay technically not convince simultaneously. Something stupid is that you should buy two of the same models as possible, because the mattress heights differ otherwise.

600 or 700 euros for Röwa mattress in beds-retail, we did not want to spend also. Unfortunately, administration in our region is no way to lie on the Badenia Irisette products sample (at least not under the proper name). The traders who were listed in the Badenia Site List have taken the products from the program. I guess because of the Internet competition is simply too large. And only towards suspected we did not order the products.

In a regional furniture store, we then discovered the Diamona Perfect Fit Plus, the two of us in construction (keyword: 3-elasticities principle) as well as convincing lie technically has. As Stiftung Warentest, we found that H3 for both of us is the right choice - despite our Körpergewichtsunterchieds! Ordered but we have online, as around 390 Euros the difference in price about 90 euros per mattress was.
On top of that you indeed for online orders always has a right of withdrawal. Therefore ourselves the friendly Karstadt salesman advised that the mattresses prefer to shop online, if you are not sure. A withdrawal / cancellation in the shop is possible only in exceptional cases - therefore sure to ask for the conditions before buying!

CONCLUSION:
After six weeks Diamona Perfect Plus I can now only say: top !! The mattress is not too heavy (for transporting and for turning over), had just two weeks after losing the characteristic odor and is very convenient for our backs :-). The removable zipped reference feels very valuable.
Our mattresses research has shown that the so-called non-binding price recommendations of standard products are all astronomical prices. When Diamona we had a good price / performance ratio-feeling - but only with regard to the favorable online quotes! For the furniture store was the so-called "super offer" 470 Euro! For us, the mattress is not yet a worthy test champion.
Another note for shipment: The Diamona shipped "unfolded" by carrier or (usually slightly cheaper) in a box via DHL, the mattress is something bent or rolled.

Tip:
-----
We have allowed ourselves two height-adjustable bed bases with 42 spring bars. Compared to our 28ern we could feel at home while sleeping sample the difference actually. Previous mattress protector (between frame and mattress) we have omitted for better "breathability".
