Apartment Therapy on Questions

Questions are good. With so many questions coming in, and not enough answers, the thought occured to us to post good ones in the hopes that answers would accrue in the comment box for the puzzled person (and us as well). Here goes:

Do you know anything about pocket spring mattresses? I have been searching forever (years) for a pocket spring mattress that I can buy in the US (there are lots of English manufacturers but none of them deliver here). De La Espada sells one but it's over $2000. I abhor the box-spring pair but it is the only thing sold in the US, apparently.

If I won't be able to buy one in America for under $1000, can I just use a mattress without a box spring on a platform bed?

Thank you,
