Casper (https://www.casper.com) is a company that sells mattresses directly to the consumer.

1 year ago, I bought a King Size Casper Mattress at a cost of $950. I spent most of the past year staying at my girlfriend's place in San Francisco (where I work) so the mattress has probably been used 3 months out of 12 months.

It is in great condition and instead of paying $950 + shipping for a new one, you can get an almost new one for more than 50% of the cost - $400.

I will throw in a boxspring if you would like one for $50 for a grand total of $450.

Honestly, don't go and buy a new mattress from casper when you can get this for more than 50% off and it has barely been used.
