New foam mattress + topper

Perhaps “false advertising” is too strong a phase, I was referring to discrepancies between descriptions on the website and what the delivered mattress actually contained, as well as tears appearing on the foam itself:

I am also considering Brooklyn Bedding models, but wanted your opinion of the 4lb and 5lb density foam, is this durable enough for two people (400 lbs total) on the mattress, or would it be more advisable to stick with the 7lb density foam in the Select Foam models?

Thanks.
