Review left on Jan 15, 2016

Disagree with Consumer Report. Sags in center in 1 mo.

Store trial OK and firm but told it was softer from trial use. Mine would be harder but soften in short time. It has, after only one month, right in the center. Edge much firmer and more comfortable than spring area, sags at hip line on 140 lb 5' 2" gal. after an hour use. Our heads slip down off pillow. Only two layers of foam on top of springs gives husband (5'10" 212 lbs.) a feeling of sleeping on an egg carton. Got an iSeries Expression, (hardest mattress) put a thick pad on it and he is fine. I put an additional box store 1" foam topper on my side and with the mattress support and the added softness it's great. Beats the iSeries Promenence for a grand less and no more back ache.

Thank you for sharing your experience with the iSeries collection. In regards to the sagging in the center, please make sure that your bed frame is providing the proper center support that extends to the floor. For reference, please see our online warranty brochure: http://bit.ly/1K1Zdqr
