While innerspring mattresses are the most common type of mattress on the market, they also have the fewest satisfied owners. SleepLikeTheDead.com reports that just 63 percent of innerspring owners are happy with their mattress, compared with 75 percent who own other types. Site editors say the subpar rating directly correlates to subpar durability. At least one in four innerspring owners says that within three years, the mattress developed significant problems with sagging that made it less comfortable.
Nevertheless, some innerspring brands perform well over time, earning favorable reviews from experts and owners. Among innerspring mattresses, the Simmons Beautyrest line (Est. $400 to $5,100, queen set) earns the greatest number of high ratings, making it our Best Reviewed model. This line features individually pocketed coils, which help reduce motion transfer -- meaning that your partner's tossing and turning is less likely to affect your side of the bed. In addition, some models feature latex, memory, and/or gel foam, for greater comfort.
One Beautyrest model scores high on a lab test of innerspring and memory foam mattresses, earning good scores for durability and support. In addition, more than 100 owners give the line an average rating of 73 out of 100 on Viewpoints.com, with many praising its comfort and firmness. The Beautyrest earns slightly above-average ratings on SleepLikeTheDead.com, compared with other innerspring mattresses. This figure is based on more than 600 user comments. Site editors note that users report problems with sagging, although this is a common innerspring problem.
Another innerspring line that gets almost as many positive reviews is the Sealy Posturepedic (Est. $500 to $1,500, queen set) . Basic models in this line feature coils that are positioned to provide extra support in the center third of the mattress, where the heavier parts of the body rest. Higher-end models feature pocketed coils and gel-infused foam.
The Posturepedic is one of the highest-rated innerspring lines on SleepLikeTheDead.com, with more than 780 owner comments analyzed. Owners indicate that the mattress relieves pain initially. Over time, however, a significant number of users find that it begins to sag, which can make it uncomfortable. Owners posting to Viewpoints.com report similar results. The Posturepedic has recently reduced its warranty to 10 years, which is relatively short among mattresses, but indications are that other major innerspring manufacturers plan to follow suit.
A relatively new innerspring line that garners comparable reviews to the Posturepedic is the Serta iSeries (Est. $1,500 to $3,400, queen set) . This line, which starts at a much higher price point than the Beautyrest or the Posturepedic, features pocketed coils topped with memory foam. Feedback from more than 100 users, analyzed by SleepLikeTheDead.com, indicates that the iSeries is comfortable and isolates motion well -- but the line is relatively new, so historical information regarding durability is not yet available.
