Recommend bunk beds in Dublin

So I'm planning to replace 2 single beds with a bunk bed, one with a double in the bottom and a single on top. I've googled them and there are different ones available, but it's hard to tell from looking at pictures if they're sturdy or good quality, etc.
So has anyone bought or know of a place that sells good quality bunk beds? Bonus if they deliver and take away the old ones.

I have just bought the "solar bunk" from meubles in kilkenny, which is a double on the bottom and single on top. I'm not allowed post a link here but if you google it you should be able to find it.
Theyre not in Dublin but I am and the delivery people were also extremely helpful so overall would highly recommend
Its very solid (&heavy!) and easy to put together. It was delivered the week after ordering too whereas some places said it would take quite a few weeks to deliver. Another thing to watch out for is a number of other sites have "small double" bases which are a 4" mattress in the base.
