Hi jburns,
Congratulations on your new mattress 
You certainly made a great quality/value choice and I’m looking forward to your comments and feedback once you’ve received it and of course have had the chance to sleep on it for a bit…
It’s not something that I would suggest on a permanent basis but if it’s just for the short term it would probably be fine as long as you check underneath it on a regular basis and also let the bottom air out once or twice a week (see post #106 here).
