Challenges
Before implementing Planet, What The Sleep faced several common challenges for stores with high AOV and complementary products:
1. Increase order value without relying on heavy discounts
Many of their main products, such as mattresses and bed bases, already had high value. Offering broad discounts puts their margins at risk. The challenge was to provide incentives to increase AOV without devaluing the product.
2. Show relevant suggestions without interrupting the purchase
Because their catalog includes items meant to be purchased together, they needed a solution that would display recommendations on product pages and directly in the cart, without disruptive pop-ups, redirects, or extra steps.
3. Activate promotions without overwhelming the message
Combining bundles, cart upsells, and promotional codes can become confusing if not presented clearly. Their challenge was to coordinate all these incentives without creating friction or excessive promotional noise.
The Solution with Planet
The collaboration with Planet was facilitated through Numéricco, an eCommerce expert agency, and an official Planet partner. They were the ones who recommended implementing the app to maximize the value of each cart and utilize Planet’s advanced personalization options to their fullest. The result: a much stronger promotional strategy without losing brand consistency or identity.
Cart with visual upsells and BOGOs on product pages
What The Sleep uses two types of upsells at different moments of the buying process:
In the cart, they suggest complementary or related products automatically, thanks to the integration with Shopify’s official Search & Discovery app. For example, if a customer adds a mattress, a related pillow or accessory appears in the cart.
On the product page, they apply BOGO (Buy One Get One) offers configured with Planet’s native functionality, making them part of the purchase flow.
Dynamic progress bar
They use a personalized progress bar that shows how much is left to unlock a discount on the entire order. It’s not just for free shipping or gifts, it’s a direct incentive that encourages customers to add more to their cart, increasing the average order value (AOV) organically.
Discount code field
The cart includes a visible field for entering promo codes, making it easier to capitalize on external campaigns (like newsletters) without adding friction during checkout.
Bundle discounts and global promotions
A core strategy for What The Sleep is selling bundles, like mattress + bed base or mattress + storage base. These sets meet specific customer needs and offer a higher perceived value without requiring deep individual discounts.
They also activate storewide discounts during special events like launches or seasonal campaigns. Both types of promotions coexist smoothly thanks to Planet’s advanced segmentation, which allows them full control while maximizing impact without hurting margins.
Results
Increased average order value
Thanks to the progress bar and bundle promotions, customers are more likely to add one or more products to unlock benefits, raising final order values without aggressive discounting.
Improved shopping experience
The slide-out cart becomes a guided decision space: visual recommendations, a discount code field, and a compelling incentive bar all work together naturally, helping the shopper without overwhelming them.
Simultaneous promotions, no friction
Planet allows them to run multiple promotions (bundles, storewide discounts, codes) with full control over what applies to each segment, product, or condition. This prevents errors and keeps messaging consistent.
Greater perceived value
By presenting full packs and showing discounts as something to unlock, not just a generic markdown, they’ve strengthened their brand image and product value.
The case of What The Sleep shows that with the right tool, it’s possible to increase AOV without bombarding customers with promotions or sacrificing margins.
