Side-by-side sleep-position guide on pillow page: +5.4% RPU
Test run byDRIP AgencyCRO agency
Commentary byLiftArchiveOur analysis, not theirsReplacing a single-slide sleep-position carousel with a side-by-side guide on the BLACKROLL recovery pillow page lifted revenue per user by 5.4%.
DRIP Agency ran this test for BLACKROLL, a German recovery and wellness brand, and published it in its own case study.
The variant also cut the number of bullets and made each position's callout more direct.
- Revenue per user: +5.4% against the carousel version.
- Extra revenue during the test: about EUR 15.3K. This is revenue earned while the test ran, not a yearly projection.
- Significance, sample size and test length were not shared.
The change
A swipe carousel of sleep positions becomes one side-by-side guide.
Simplified mockup drawn by LiftArchive from the shared screenshots.
Control
The pillow product page explained sleep positions in a carousel that showed one position per slide. Shoppers had to swipe to compare side, back and stomach sleeping.
Variant
All sleep positions sat next to each other in one view. Each had fewer bullets and a clearer callout saying how the pillow suits that position.
Why it likely won
Our reading of the result, not the practitioner's claim.
- DRIP's research found fit by sleep position was a major worry for pillow buyers. Seeing every position at once answers "will this fit me?" faster.
- A carousel hides most of its content. Many shoppers never swipe past the first slide.
- Fewer bullets cut reading effort on mobile, where DRIP says about 80% of BLACKROLL traffic came from.
Caveats: Vendor-reported result from the agency that ran the test. Revenue is for the test runtime only, and significance, sample size and duration were not stated.

How to run this test on your store
- Hypothesis
- If we show all sleep positions side by side with short, direct callouts instead of a swipe carousel, then revenue per user will rise because shoppers can confirm the product fits them without extra effort.
- Primary metric
- Revenue per user
- Guardrails
- Return rate for the product
- Add-to-cart rate
- Page scroll depth on mobile
- Who should test it
- Stores selling products where fit depends on the buyer's body or habits, like pillows, mattresses, shoes or braces. It matters less for products with no fit question.
Questions
Are carousels bad for product pages?
Not always, but content on later slides is often never seen.
When shoppers need to compare options, showing them together usually works better.
How do you help shoppers pick the right pillow?
Answer the fit question directly. Show which sleep position each option suits, with one short line per position.
