Hello astronomy cast fans, Fraser here.

Once again, this episode of astronomy cast

is brought to you by Casper mattresses.

And Casper has been a sponsor for astronomy cast now

40 years and years.

And I've been using my Casper mattress for years and years now.

And I'm still super happy with it.

So I think one of the big questions that you might have

is like does this thing hold up?

Is it still comfortable?

Does it still give you that sort of nice mix of sink and bounce?

And it does.

I can tell you now for multiple years.

And I really think if you are interested,

if you just time for a mattress and you're

avoiding that trip to the mattress store,

because you don't want to spend the money.

And you know that it's going to be some tough sales people.

And you're not really sure you're going to be really happy with it.

But you've got this old mattress and it's time to get rid of it.

So order a Casper mattress.

You can keep it, just sleep on it for 100 days.
