Marshall mattress not what it used to be

I’ve had Marshall mattresses for over 25 years and have been very satisfied, so I was very excited to purchase this new Marshall mattress (Crafted, Acadia Plush Euro Top). I’ve had the mattress for only a week and I am already very disappointed. For starters, the workmanship on the mattress itself is very sloppy. In two places the inner filling is sticking out from underneath the seam. Next, there are already visible body indentations in the mattress. After only one week! Finally the bed feels nothing like the model in the showroom. I like a soft mattress, where I sink into the bed. That is why I purchased the Plush Euro Top model. The mattress I received is firm. I understand that you can’t directly compare with the floor model ( which multiple people had lied on), but this does not feel like the same mattress at all. And if the floor model is softer because multiple people had lied on it, why are there no indentations? I suspect the quality of the floor model to be different from what the customer gets. Very unhappy and disappointed. Marshall, you have lost a loyal customer.
