I flew Ryanair for the first time from Bournemouth to Lanzagrotte in May, with a bit of trepidation given their reputation! 
It was fine, absolutely fine.
As Biggriff pointed out you pay for a seat. The parachute is extra!

I could tell you why I won't fly with them and customer service/imaginary charges don't get a look in 
I have very low expectations Al, after all I drive an Omega..... 
Both the FAA and CAA have gone to a shitload of effort to stop aircraft cabins from burning. One key way of doing this is to remove all dry waste from cabins by way of regular, intensive cleaning...
See here for the, very, bare bones of it:

This allows small, dry debris to collect unimpeded in all the nooks and crannies. This the creates a significant fire hazard, rendering the latent retardant properties of the aircraft interior useless.
It was not unusual to find a Ryanair aircraft impounded in Diamond Hanger at Stansted due to deliberate ignorance of the CAA requirements to minimise the build up of potentially catastrophic debris.
In 2006, the Cabin Cleaning contract for Easyjet at Gatwick alone was £30,000 per week, Ryanairs was worth about £500... at the time, Easyjet had summat in the order of 15 aircraft based at Gatwick, Ryanair had about 5 iirc
Most airlines, including the likes of Monarch, Thomas Cook and Easyjet will ensure that the aircraft are cleaned properly once a day, and cleaned thoroughly, ie seat cushions lifted etc, once a week...
Both BA and Easyjet spend alot of time and money ensuring their aircraft look their best with fabric seat covers being removed and washed once a month, and carpets being replaced every six to eight weeks.
People may well bleat about Easyjet, especially when they suffer the shitty end of their scheduling, but they do at least try to operate as a professional airline... something Ryanair could never claim to
