What customers say
The Serta iComfortPro Granby generally garners a mixed-to-positive initial reception, driven primarily by its advanced cooling capabilities and robust support structure. Customers frequently highlight the effectiveness of the iComfortPro technology, noting that the mattress maintains a comfortable temperature throughout the night, a significant win for hot sleepers. Initial comfort is often described as supportive yet conforming, offering excellent motion isolation, making it a popular choice for couples. However, the sentiment trajectory often shifts over time. A recurring theme in critical feedback centers on the mattress's long-term durability and firmness profile. Many users report that the Granby feels significantly firmer than advertised, causing pressure points, particularly for strict side sleepers seeking deep contouring. More critically, a substantial segment of the customer base expresses disappointment regarding premature sagging and the development of deep body impressions, sometimes within two years of purchase. This durability issue severely impacts the perceived value, especially given the premium price tag associated with the iComfortPro line. While the initial sleep experience is highly rated, the subsequent decline in structural integrity leads to frustration and a feeling that the investment did not hold up over time. Therefore, while initial satisfaction is high regarding features like cooling and motion transfer, the overall long-term sentiment is tempered by concerns over structural longevity.
