Hi mw1197,
Local vs online and the importance of testing a mattress in person can certainly be a consideration for many people in their personal value equation. If the current version of the Emily is a memory foam / pocket coil mattress then it would also be an apples to oranges comparison because the Dreamfoam mattresses you are looking at are latex / polyfoam mattresses.
Either way and regardless of your material preferences you have some great final choices that are all in the “good value” range 
I’m looking forward to hearing about your decision.
