I was struggling to find a mattress that would be within my price range and still be one that came highly reccomded! Polysleep was the only company that fit my personal check list of what I needed from a mattress, in order to get a proper night's sleep. 

The shipping was extremely fast, it arrived and expanded in no time. Was slightly soft on the first night however the foam did firm up after a few rests. I've now had the mattress for about a month give or take. It has definitely held up since, and provided adequate back support. 

My only complaint with the mattress is that it is just not quite as firm as I am used to, I might explore some mattress toppers that are on the firmer side... I don't think it will have much of an impact but it's something I'm willing to explore.
