Mattress product page copy rewrite: +13.9% checkouts
Test run byGrowthRockCRO agency
Commentary byLiftArchiveOur analysis, not theirsRewriting the Amerisleep mattress product page lifted checkouts by 13.9%, at 98% confidence.
GrowthRock ran the A/B test and published it on the GrowthRock blog; the new copy was written by Brian Speronello of Accelerated Conversions.
Several copy changes shipped together, so the lift belongs to the rewrite as a whole, not to any one section.
- Checkouts: +13.9% for the rewritten page, at 98% confidence.
- Each variation logged hundreds of conversions, and the test ran across multiple buying cycles.
- Traffic and conversion rates were not shared, because of the agreement with Amerisleep.
The change
The rewrite adds a sleep-benefits section and comparison claims against other mattresses.

Control
The original Revere mattress product page, with Amerisleep's existing product copy.
Variant
A rewritten page. It added a short section linking better sleep to health, work performance and quality of life, a nudge about the cost of doing nothing, and comparison claims against traditional memory foam and other mattresses.
Why it likely won
Our reading of the result, not the practitioner's claim.
- Mattress buyers rarely want a mattress for its own sake. Linking sleep to health and better days at work may have given the purchase a stronger reason.
- Many shoppers who leave don't buy elsewhere; they just put it off. Copy about the cost of staying put may have cut that delay.
- Specific comparisons, such as foam that recovers its shape faster than memory foam, give shoppers a clear reason to pick this brand over a rival.
Caveats: This was a bundled copy rewrite, so no single section can take the credit. Traffic and conversion rates were not disclosed, and the case study dates from around 2017.

How to run this test on your store
- Hypothesis
- If we rewrite product page copy to connect the product to the deeper outcomes buyers want and compare it clearly against alternatives, then checkouts will rise because shoppers get a stronger reason to buy now and to buy from us.
- Primary metric
- Completed checkouts per product page visitor
- Guardrails
- Return rate
- Average order value
- Product page bounce rate
- Who should test it
- Brands selling a considered, higher-priced product where buyers compare options, such as mattresses, furniture or appliances. It is less likely to matter for cheap impulse buys, and any comparison claims must be true and provable.
Questions
Can rewriting product page copy alone raise sales?
In this test it did: checkouts rose 13.9% with no change to price or offer.
Results depend on how weak the original copy was.
Should I compare my product to competitors on the product page?
Specific comparisons, such as faster shape recovery than memory foam, can help shoppers choose.
Keep every claim accurate, because vague or false claims erode trust and can break advertising rules.
Is benefit-led copy better than listing features?
Usually it helps to show what a feature does for the buyer's life.
This rewrite went a step further and tied sleep to health and work, not just to rest.
