After one month, our icomfort is going back and being replaced by a regular mattress. I found the mattress hot sleeping and found it difficult to roll over during the night. After one month, the mattress had our body imprints and the sides were high. The mattress store is taking it back for a fee which we were happy to pay to get rid of it. If you're thinking of buying one - DON'T.

I haves been a fan of isoform mattresses for ten years. So has my father and sister (in 2011 they both upgraded to isoform adjustable beds).

My huz and I realized it was time to upsize to a king when our little sons could no longer squeeze in in the morning. We sprung for the Luna bed that features extra foam topper and is extra thick. As much as we loved our former isoform now I feel like I have gone to heaven. It feels like sleeping on a bed of goose down that never loses its loft.

Received Prodigy on 1/28/12. Loved it for the first 9 weeks. Then out of blue started having mid to lower back stiffness. I only way 205lbs. Place I bought from only offers exchange for equal or greater value, within 90 days. Doesn't honor 120 day trial Serta declares on their web site, nor do they honor Serta's refund policy if not satisfied. I am going to contact Serta to see if they honor the policy on their own wed site but don't have high hopes since have statement their vendors can have different policy(written in lighter text so as not to notice). I can upgrade to Renewal but very leery to spend more money on a bed that could end up with same problems in another 9 weeks.
