I purchased two twin sets of Simmons Beauyrest Classic bedding 01/2008 and one the mattresses has begun to compress in the center. I was told this is normal "compaction" for this style mattress.

I would advise prospective mattress purchasers to avoid Simmons Bedding products. Thank you. Leonard Silverman, CT. read full review »
