Hi Aimee,
In terms of the quality of the materials and the value of the mattress … you made a great choice. In terms of how you feel about actually sleeping on the mattress or how you feel about latex itself … only your own experience will tell you this for sure because other people may have very different preferences or perceptions from your own so you will know when you have a chance to sleep on it … and then hopefully you can tell us how it feels for you 
In a word … no. You can read more about latex allergies in post #2 here.
As you can see in post #89 here about protectors … the St Dormeir is a great choice as well.
So in quality and value terms you certainly did well. Because so many people like latex … the odds are also good that you will be happy with your choice.
So I hope you have the chance to give us your feedback when you’ve had the chance to sleep on it … and in the meantime … congratulations on your new mattress
Phoenix
