Bottom line

The Serta iSeries may appeal to customers looking for a relatively inexpensive way to reap the benefits of memory foam. It combines gel-infused memory foam with an innerspring unit, which allows it to achieve a lower price range than many all-foam mattress lines do. This line replaces the Serta Perfect Day, which had some sagging issues, according to SleepLikeTheDead.com. It remains to be seen if the iSeries will experience similar problems.

Comfort

Isolates motion well. Thanks to its pocketed coils, the Serta iSeries line is good at stopping motion transfer, according to SleepLikeTheDead.com. Editors say it performs better than average in this regard, compared with other innerspring mattresses as well as all mattresses overall. It also performs at an above average rate for pain relief, which the editors attribute to the presence of memory foam in some models. The line appears to be too new to determine if sagging will be a problem; however, the Perfect Day line, which the iSeries replaces, tended to pose sagging problems for at least one in four owners, according to SleepLikeTheDead.com.

Value

Long-term warranty. The Serta iSeries mattress line sells for between $1,500 and $3,400 for a queen set, meaning it starts somewhat higher than other innerspring lines. Step-up features such as pocketed coils and gel-infused memory foam account for its relatively expensive opening price. The line carries a generous 25-year warranty, which is prorated after the first 15. The warranty covers sagging, but only if the indentation reaches at least 1.5 inches for quilted-top mattresses, or 0.75 inch for smooth-top mattresses. Purchasers of the iSeries are also covered by a trial period that allows them to test the mattress for 120 days and exchange it if they're unhappy.

Durability

Difficult to assess. The Serta iSeries mattress is relatively new, which makes it difficult to assess its long-term durability. SleepLikeTheDead.com reports that sagging, particularly during the first three years, was a top complaint of the Perfect Day, which the iSeries replaces. Sagging is a major cause of diminished mattress longevity. At least one in four Perfect Day owners had problems with sagging, according to SleepLikeTheDead.com, although in one comprehensive professional test of mattresses, a Perfect Day model earned a top score for durability. Editors at SleepLikeTheDead.com add that iSeries models with thick pillow tops have the most potential for sagging problems.
