We needed a very firm mattress and had the Brooklyn Bedding Craftsman LuxFirm 13" Mattress Recommended based on its coil count and what appeared to be similar to the Serta Luxe Chamblee 12.5" Firm that we loved. The Brooklyn Bedding one came rolled up in a box that was far lighter weight than the mattress we were trying to match. We tried the mattress for almost a month and gave up thinking we could get used to a cheap mattress. There is no edge support (it has to roll up into a box to ship), and my 160 lbs was too much for it. This mattress is not offered on this site, so maybe they have a cheaper line for third party vendors???
