Hello astronomy cast fans, Fraser here.

So once again I wanted to give a shout out to Casper.com who is our generous sponsor for

astronomy cast.

Now we talked about this in the past but I thought I would just sort of give you all the

story again for those who missed it.

So Casper gave us a mattress to try out.

I had to leave mine in the States at my wife's house.

But I really liked the mattress and so I ordered one for myself.

Then I ordered another one for the spare bedroom.

So this is the mattress that I'm slipping on and I think you're going to want to sleep

on it as well.

It's a high quality mattress.

It's got this cool kind of latex foam with a memory foam.

And when you get the thing it's in this box that really defies the laws of space and

time and then you cut the box open and the thing sort of inflates in front of you and it's

really cool.

I really like it.

Casper mattresses cost $500 for twin size, $750 for full size, $950 for a king which is

less than what you pay for a traditional mattress.

I mean it can be over $1500.

It's totally online.

You just order it.
