Their "niche" market of direct sales and delivery of foam mattresses already seems pretty crowded. I was in the market last year, and after some research it seemed like there is very little difference between the offerings from Casper, Leesa, T&N, Purple, and others.

Plus they surf the 'ethical marketing' wave very big time.

e.g: If you buy a mattress from us, we'll donate one to someone in need.

TLDR -> You can only buy 2 mattresses from us and we will only give one to you, cash in the moral benefit of being 'good', possibly get tax exemption on your dollar. And btw, by doing this we don't just insult your intelligence, we also kill the competition as there are people competing on the market for people in need already.

Fun hint, I remember shopping for a mattress few months ago, eventually seeing their ads following me everywhere I'd go on the internet for a few weeks. But not only that, 2 days later I received an actual letter with a 'deal' from Casper.

Long story short, casper no thanks!

Lookup "Zinus Memory Foam 12 Inch Green Tea Mattress" on Amazon. It's an incredible mail-order memory foam mattress for under $200. 7000+ 4+ reviews.

Your dislike is unfortunately a common flaw with Casper like foam mattresses which largely just have a number of layers of foam on top of one another. You can reinforce or line the edges with firmer foam/material so that sitting on the edge is more comfortable and robust, but I think a lot of mass manufacturers avoid that to keep their costs low.

I recall seeing the difference by going to a custom foam mattress store.

In terms of comfort, they're nothing special. A bit too firm for my tastes.

They're definitely fantastic at marketing though.
