We bought a mattress from Swan beds, Cork about 5 years ago. We tried all their mattresses on display and chose a top of their range one. It's king size and really deep and we did struggle to get it up our tiny stairs! We work in a physical job (we run a glamping site on Cape Clear) and really value our sleep and comfort. Every night I am so grateful we chose this one. It's still like lying on a supporting cloud. It is an amazing mattress and feels the same as the first day we bought it. It really is worth spending that little bit more for quality and reliability if you value a good comfortable sleep.
