A week ago I started shopping around for mattresses and found how overwhelming this can be. Anything that seems good enough in brick and mortar stores have a starting price of 1500 USD plus shipping.

Luckily (or not) I found a few online only companies selling mattresses and made a comparison sheet with some data [1] about them.

I'm trying to get the best bang for the buck and spent the entire day researching about these companies and still can't pick a winner.

Also, just as I was finishing my sheet I found 4 more companies (no data in the sheet) to bring the choices to a total of 14 options.

The bright side is that most of the companies offer a long period of free trial and donate the mattress at the end if I want to get a refund.

I sleep mostly on my side and stomach, so I think a soft mattress makes more sense, but still don't want to try a random option "just because it's free".

What do you sleep on? Any recommendation or advices while buying mattresses?
