It's a <a class="bbc_url" href="http://www.topsellerie.co.uk">http://www.topsellerie.co.uk</a> seat, not cheap if you add options but it's great, mine is the low and back option and I'd rate it 8/10 for a whole days ride comfort, 10/10 for quality, this one has their own base but you can send your own to be remade, it's a faff if you have to send yours of so I just ordered it complete and if I sell later on. I have the old one, for me it's much better than the firm wide and flat standard seat and yes a day on the bikes no problem, it has a gel for the rider and tbh I think you'd have to go some to better it, some of the guys on here whole travel world wide etc have used extreme options like sheep skins etc, others have cheaper uk made seats that I am told are excellent too, search and I'm sure you will find them. 
Oh forgot to say check the bargains section of the site they sell some off check at times.
