Sleepopolis History

As a Pillar4 Media property, Sleepopolis conducts in-person product testing and publishes expert-backed, comprehensive reviews of mattresses and sleep accessories. 

Pillar4 purchased Sleepopolis in 2020 from a subsidiary of JAKK media, who acquired the site from its original founder, Derek Hales, in 2017. Pillar4 is not associated with JAKK Media or Derek Hales. Upon acquiring the site, we remodeled Sleepopolis and created its unique set of product-testing and editorial standards, which we continue to develop and fine-tune today. 

This methodology forms the backbone of our review process. We’ve used it to test more than 500 mattresses, and the resulting data has led more than 145,000 readers to the best bed for them. 

How Sleepopolis Makes Money

Sleepopolis makes money in a few different ways, including affiliate links and brand partnerships. 

Affiliate links—links that take you from Sleepopolis to a brand’s site—enable us to earn money from brands in exchange for referring you to their product. Simply put, if you click an affiliate link and end up buying the product we’ve linked to (or, in some cases, visiting the brand’s website at all), we get a small cut of the brand’s proceeds. 

We also partner with brands to review and feature their products, which they send to our testing studio for free. 

However, we do not ever guarantee that we will review a product favorably. We uphold our editorial integrity by running every product in a given category through the same rigorous testing process and reporting the results without bias. We don’t sugarcoat or downplay our reactions to the products we test, regardless of any affiliate relationship with the brand. 

In an effort to reflect the broad scope of the sleep industry, we also strive to review a range of products from different categories, including products from brands with whom we have no pre-existing affiliations or agreements.

Sleepopolis FAQs

Who owns Sleepopolis?

Since 2020, Sleepopolis has been owned and operated by Pillar4 Media, a media platform dedicated to helping people find the right health and wellness products for their needs. 

Is Sleepopolis the same as Pillar4’s other mattress review sites?

No. Although Pillar4 owns other mattress review sites in addition to Sleepopolis (including Mattress Clarity and Mattress Nerd), Sleepopolis is a distinct brand with its own product testing and review methodology. 

What makes Sleepopolis different from other mattress review sites online? 

When our expert testers review a mattress for Sleepopolis, they apply a unique set of standards to its performance. For example, Sleepopolis weighs a bed’s cooling capabilities and edge support more heavily than other sites—we know our audience cares a lot about these metrics in particular, so they have the most impact on a bed’s overall score. 

Sleepopolis also covers a wide swath of sleep-related topics. Mattress reviews might be our main focus, but we regularly publish pieces on the science behind good sleep hygiene, how sleep intersects with various health conditions, and general tips for getting a better night’s rest.

Finally, Sleepopolis relies on a network of medical professionals and other sleep experts to ensure its content is trustworthy and thorough. 

Who tests the mattresses for Sleepopolis? 

We have an in-house team of dedicated mattress experts who test beds and sleep accessories. Some of these testers also write Sleepopolis content, whereas others test products and provide notes full-time. 

We also frequently recruit contributing testers to provide us with even more data, or with a relevant perspective. For example, we sometimes need testers in a certain age range, testers with a certain body type, or testers with a specific health condition. 

All of our testers are compensated for their time, and we never try to influence their feedback. If they dislike a product, you’ll know about it! 

Do Sleepopolis testers really use the mattresses and products they test?

Yes! All of our testing is done in-person with many hands-on steps. Several of our testers have ended up purchasing a product that tests well in our studio to have in their home—it’s both a perk and a danger of the job.
