I was very skeptical when ordering this, after spending 18moths on a different budget mattress that had our backs in buts for months. However, I am super impressed, the mattress arrived the day after I ordered, and it is super comfy! There was no smell on opening as some other reviews indicate. I've spent a couple of days sleeping on it and it feels fantastic. No more backache on waking up and I can't wait to go to bed at night. By far my favorite purchase so far this year.
