Customization Options and Special Features

Serta iSeries mattresses come in four different models, which are available in a variety of common mattress sizes. Because of this variety in model and size, Serta does not offer any customization options. The beds are designed to be optimized for different types of sleepers rather than to be customized for other types of needs. 

Apps and Accessories

In addition to the Serta iSeries mattresses, Serta also sells a selection of pairable bed frames including a foundation and three adjustable bases. Serta also sells a selection of bed accessories, including sheet sets, pillows and mattress toppers. 

Additionally, Serta offers an app that can be paired with the company’s adjustable base that allows users to control the positioning of the foundation via smartphone. 

Warranties and Discounts

Serta mattresses include a 120-day sleep trial period, though this may not apply if the mattress is purchased through a retailer that does not extend the same trial options. 

Serta offers a limited manufacturer warranty on all of its mattresses, including the iSeries mattresses. The iSeries mattresses come with a 10-year limited warranty, which covers issues caused by faults or defects in the mattress that results in damage or degradation. The warranty does not cover standard wear and tear, misuse or abuse or personal preferences. Serta may issue a full replacement to address any issues covered under the warranty, but it does not extend the warranty length another 10 years for the replacement mattress.

What Users Say

The Serta iSeries mattresses are well-reviewed among customers who have purchased the mattress. However, the Serta brand overall is not as positively viewed. The company has a score of 2.7 out of 5 on TrustPilot and 1.17 out of 5 on Better Business Bureau (BBB), with more than 110 complaints filed against it. The company is not BBB accredited and has an F rating on the site.

Most reviews of the iSeries mattress line found the beds to be comfortable, providing firmness that meets expectations and a considerable amount of support that helps to address pain points. “We are completely satisfied,” one reviewer wrote. Others found the mattress “very comfortable and firm.” One reviewer went so far as to say they “now sleep better than I have in years.”

However, the mattress line has not met everyone’s expectations. Durability seems to be an issue, and some reviewers have found humps and depressions forming in the mattress. The company also has been subject to complaints stemming from its customer service. Some have complained the company is not responsive to warranty claims and often will not replace mattresses despite requests to do so.

Who Should Purchase a Serta iSeries Mattress?

Because the Serta iSeries offers a variety of different mattresses with varying firmness and types, there is likely a mattress available that will suit your style of sleeping. In general, the iSeries is likely best for those who prefer medium firmness, a soft style top and sleep on their side. However, there are options within the line that work better for those in need of a firmer mattress and those who sleep on their back or stomach as well.
