Original Classic Matratze

I love my Emma mattress, the classic not the hybrid. It's a tricky recommendation because a huge amount is personal preference. I get along well with the modern memory foam, but if you have a sprung mattress a hybrid might feel more normal. 

Eine Emma habe ich auch schon als Gast in einem Gästebett erlebt. Die erste Nacht dachte ich: "himmlisch". Aber noch ein paar Nächte mehr, und ich wusste, dass diese Matratze nicht für mich gemacht ist.

I just got rid of an Emma memory foam mattress for a latex one. Game changer - less hot, more supportive as a side sleeper and does not make you sink into it

All of those mattresses are memory foam type mattresses. That's oil based and bad for the environment. Also hot AF in the summer. I work in the bed trade. For decent value natural filled mattresses, Highgrove are great. If you have a high budget, try out Harrison Spinks, which are vastly more comfortable, 100% natural and chemical free, plus 100% recyclable.

The downside of this is that the returns rate for Simba/Casper/Emma is horrendously high. All that foam, where does it go? Those mattresses aren't resold.

Emma's memory foam mattresses are very highly rated in Germany, and they have regular sales. They are the go-to standard for affordable and decent memory foam mattresses in Germany. If you want something higher quality (thicker layer of denser memory foam and denser underlying foam, and longer lasting, but more expensive), sleepfactory.de and dami.de (they're both the same company) have excellent memory foam mattresses for the price. I've owned both. If you have the budget, I'd recommend the latter: memory foam mattresses' lifespan isn't that long, and sleep factory.de's last significantly longer because they're denser. But their customer service is very poor, while Emma's is excellent.
