I am a 22-year-old guy who just moved to a new city and has been on an airmattress for the last two weeks.  Long story short, I'm buying a bed this weekend.  I got it down to either bedinabox or a night therapy bed from sams club.  Then I discovered this site, heard about foambymail, and saw I could get a 5.3lb memory foam bed for next to nothing.  Should I do it?  Or would bedinabox / night therapy be better?

I'm wondering if it will "sleep hot" and if there is any quality issue I should be aware of.  I'm also wondering if I making a mistake by not getting an expensive mattress.  Cost is not too much of an issue - I am cheap with most things, but I had allotted up to $1500 for this purchase.  Ive been erring towards the cheaper side (eg Night Therapy) because I'm young and will probably be in and out of apartments / switching cities, etc, and also because I like saving money if the product is still good.

Anyways, thoughts on foambymail, bedinabox, night therapy, or anything else I should know?  This airbed I'm on is driving me insane, I am definitely buying this weekend.

I slept on that as my comfort layer for about 3 years loved it.

Added Venus 1" 8lbs memory after that just because I found it really really cheap.

Did not make as big an improvement as I thought.

Then buy base from foambymail,ebay,or any other places popular here like mattress.net

I bought cheap 1.8 lbs base foam but if I had to do it again I would get latex for a base.

Get the Aerus with latex base.

Don't like it?

Get latex comfort layer.

You are out ~$179 or you can use the Aerus as an intermediate layer between latex base foam and comfort foam.

I would not get bed in a box. Seems expensive for what you get.

Not familiar with Sams Club stuff but if like Costco just an ok value.

Oops!

You need to buy the Aerus memory from walmart.com.

They only sell the cheap stuff at the brick'n mortar stores.

I am KILLING myself over this decision.

The Night Therapy 12" Latex mattress seems like a really good value. 7 inches of latex in a Sealy costs $2000. 

The thing that worries me though is that all the Night Therapy latex mattresses say "Firm". I am wondering how firm that is. I weight 240 pounds and my last innerspring mattress broke down and I ended up having lower back pain.
