I would describe the Quälität the mattress as well, but unfortunately the mattress is at the specified hardness 3 (up to 140 kg) vel too soft. I weigh 92 kg and was previously used only cheap mattresses from the A ... center aisle. These were simple but very strong and I was able to sleep well on it. After 5 years she was by this time and I wanted more invest in a new mattress. Because of the price and the mostly good reviews I decided for the Gigapur model with hardness 3. After about 2 weeks, the tension began to which widened in the coming weeks on muscle tightness in the back area. I have problems at first unable to recognize the mattress, but after about months with never-ending back problems I am a trial basis on my inflatable guest bed (49, -) dodged. It took a while, but the back pain disappeared completely.
My conclusion: buy mattresses on the Internet I will not probably. I think that testing the mattress is very important and it should be tailored to the bedroom, size and weight ratios. This is my opinion only in a specialized mattress dealer, although the mattresses are there only sold at significantly higher prices.
