Thanks to the advice from the Customer Service I bought two small rather than a large mattress and sleeping now on, even if my friend full of energy turns into night. In addition, I bought against my firm belief spring mattresses. My concerns were wrong. I do not feel any springs when sleeping and lying down. But I sweat less, because the mattress is better ventilated :)
Review:
Consulting 5 of 5 stars
Delivery time 5 of 5 stars
Delivery Service 5 of 5 stars (A small bribe to the delivery man and then he dragged the delivery with joy in the 4th floor.)
Quality of goods 5 of 5 stars
In any case, you did a great job and won me as a fan. The mattress I will recommend to my friends.
