The worry is that the polyester inside will begin to degrade, and it will develop a "bubble tumor". It's a very random occurrence though, I've only seen it happen three times in all the time I've been working on inflatables.
If the material surface is not discolored from UV or hydrocarbon exposure though, you're probably okay. Make sure you only utilize the floor at the proper inflation, or it may cause the threads to be overstressed during operation, which may cause the failure.
