Phoenix,
I recently purchased a 9" king-size memory foam mattress (I purchased the 4" 5lb memory foam + 5" LUX -HQ base) from The Foam Factory (I did not see this post until after I had already purchased the mattress).
My wife purchased a bed frame which will require a box spring. Given your initial post on this thread, would you recommend this knock down foundation from mattresses.net?
Although it seems ideal that the distance between slats is less than 3", I have to admit that cost is also one of the more enticing aspects of this foundation - given that the mattress itself cost about $515, I cannot really stomach spending much more than $300 for a foundation (absent a compelling reason).
Please let me know your thoughts. Thank you!
