What customers say
Customer sentiment for the Sealy Posturepedic Plus London Grove Ultra Firm Mattress is generally strong, particularly among consumers who specifically require maximum support and minimal sinkage. The primary praise centers on the mattress's exceptional firmness, which many back and stomach sleepers find crucial for maintaining proper spinal alignment and alleviating chronic back pain. Reviewers frequently commend the robust construction and perceived durability, noting that the 'Ultra Firm' designation is accurately delivered, reinforcing the high-quality reputation of the Posturepedic Plus line. The edge support and overall material quality consistently receive high marks, suggesting a product built to last. However, the sentiment is highly polarized by comfort preference. A significant segment of users, especially those who are lighter or primarily side sleepers, find the mattress excessively hard, describing it as unforgiving and leading to uncomfortable pressure points on the hips and shoulders. This highlights the necessity for consumers to be absolutely certain they need an extreme level of firmness before purchasing. Despite the premium price tag, those who benefit from the specialized support system often view the mattress as a worthwhile long-term investment in their sleep health, leading to a strong overall satisfaction score driven by its targeted performance and high quality.
