My boyfriend and I are picky sleepers so we were really reluctant about buying a mattress online but it was recommended to us by a few people already. So we went to a store that had their three mattresses on display so we could try them before we’d buy. Surprisingly, their most basic model is the one we found the most comfortable. We decided we’d give it a go and then upgrade by the end of the trial period if ever we felt like it. 
But we both know that there is no exchanging this baby. 
It is absolutely heavenly. It’s the comfiest thing I’ve ever laid on and it was ridiculously affordable in comparison to other mattresses. We also super whale threw ourselves on it and the other could barely feel any movement which is great, because I tend to move a lot at night and bother my partner. The shipping was rather quick and the setting up was a joke. I highly recommend this mattress.
