Hi Smitten94,
Welcome to the Mattress Forum! 
[quote]I wanted to know what you think about these new mattress in a box.
The first one is called bloom by Sealy. The Second one is the Douglas mattress.[/quote]
There is no meaningful information presented by Sealy on the Sleep Country web site about the componentry within their mattress, so unfortunately I can’t provide any meaningful comments about it. Before considering any mattress, make sure that you find out the information listed here so you can compare the quality of the materials and components to the durability guidelines here to make sure there are no lower quality materials or weak links in a mattress that would be a cause for concern relative to the durability and useful life of a mattress before making any purchase. If you’re able to obtain that information about the Bloom or the Vivienne, feel free to post it back here and I’ll do my best to comment upon that for you. You can look at post #52 here for some comments about the Douglas mattress.
