Project

Slumbersac is a store specializing in children's sleeping bags, where the product belongs to the apparel category, but the purchase decision is more technical than in classic fashion. A parent chooses not only the pattern and size, but also the sleeping bag construction, TOG rating, season, material, and practical details related to the child's safety and comfort.

The range includes, among others, sleeping bags with legs, classic sleeping bags, seasonal variants in 0.5 TOG, 1.0 TOG, 2.5 TOG, and 3.5 TOG, as well as solutions such as detachable sleeves and fold-over leg cuffs with ABS.

Business context

At Slumbersac, the product needs to be explained visually. A parent wants to quickly understand how a specific model differs: whether it has legs, whether the sleeves are detachable, what temperature range it covers, and whether it is suitable for summer, winter, or year-round use.

The site features product and trust messages, including detachable sleeves, fold-over leg cuffs with ABS, a Google rating of 4.8, fast shipping, and messaging about the most frequently chosen sleeping bag. This shows that the store combines emotional presentation of patterns with very practical arguments.

Challenge

In a children's sleeping bag store, the product list must handle several types of information at the same time:

• product pattern and color,
• type of construction,
• TOG categories,
• seasonality,
• functional details, e.g. sleeves, legs, zipper, material,
• trust and a sense of safety.

One image on the listing may show the print, but it does not always explain the construction. For a parent, it is important to quickly distinguish a classic sleeping bag from a sleeping bag with legs or a variant with detachable sleeves.

The second challenge is mobile. Shopping for children's products often takes place on a phone, so the interaction must feel natural: page scrolling cannot be blocked, and moving to the next image should be simple.

Solution

For Slumbersac, it is valuable to extend the product listing with a quick preview of the next product image. On hover or swipe on mobile, the user can see an additional shot that shows the sleeping bag construction or a practical detail.

Key assumptions:

• the initial category load remains lightweight,
• the second image is prepared in advance for visible products,
• additional products loaded during scrolling are also included in the prefetch mechanism,
• on mobile, a horizontal gesture is used for the gallery, while vertical movement still scrolls the page,
• the store can indicate a dedicated hover image, e.g. a shot showing detachable sleeves or legs.

The role of the hover image attribute

In such a store, a dedicated image attribute, e.g. on_hover, is especially useful. Thanks to it, the store team can decide for themselves which image best explains the product on the listing.

Examples of use:

• first image: an attractive sleeping bag pattern,
• hover image: a photo with the legs extended,
• hover image: showing detachable sleeves,
• hover image: a material or zipper detail,
• hover image: a shot showing the shape of the sleeping bag on a child.

This is important because the automatic second image from the gallery is not always the best sales image. In the case of technical-apparel products, it is better to give the merchandiser control over what the customer sees as the first interaction.

Effect for the user

A parent can more quickly assess whether the product meets a specific need: a warmer sleeping bag for winter, a lightweight year-round model, a sleeping bag with legs for a child who walks, or a model with detachable sleeves.

Benefits:

• faster recognition of the product construction,
• fewer visits to product pages just to check a detail,
• better comparison of TOG models and sleeping bag types,
• a more understandable listing on mobile,
• the ability for the store team to control the first hover image.

Why it fits Slumbersac

Slumbersac sells products that are simultaneously clothing, a sleep accessory, and a functional product for a child. The pattern aesthetics are important, but the parent pays just as much attention to practical solutions.

The hover/swipe gallery helps show:

• the differences between a classic sleeping bag and a sleeping bag with legs,
• detachable sleeves,
• fold-over leg cuffs with ABS,
• seasonality and TOG categories,
• patterns and collections in a more engaging way.

Recommended development directions

• use of the on_hover attribute to indicate the best functional image,
• separate rules for categories: sleeping bags with legs, sleeping bags, organic cotton,
• a test of whether a construction-focused hover image increases product visits,
• analysis of mobile behavior: swipe versus clicking into the product page,
• adding shorter product messages next to TOG filters.

Summary

Slumbersac is an example of an apparel store where the product image must explain the function, not just the look. A well-chosen second image on the listing can show the detail that determines the purchase: legs, sleeves, material, or the shape of the sleeping bag. The hover/swipe mechanism and the dedicated on_hover image give the store greater control over how quickly the customer understands the product.

slumbersac.pl is a store offering sleeping bags for children. In this case, communication is not focused primarily on promotional campaigns, but on providing customers with the most important information about products and customer service.
The implementation of Kowal Announcement Bar made it possible to highlight key messages at the user's first point of contact with the store. The bar is used to share information such as:

• key product features,
• shopping guidance,
• customer service information,
• organizational and shopping-related messages.

In a store with a more specialized product range, this type of bar helps create a sense of clarity and order. Customers receive basic information faster, which can influence their purchase decision or address doubts before they move on to product details. As a result, the module supports not only sales, but also the quality of customer communication.

The Slumbersac.pl store specializes in selling children’s sleeping bags and sleep accessories for young children. The brand’s products stand out for their high-quality materials, various thickness options (TOG), and a wide range of models matched to a child’s age and height.

Problem

For children’s sleeping bags, choosing the right size is much more complex than for standard clothing.

Parents often have questions:

• which sleeping bag size is suitable for the child’s age

• whether the sleeping bag length will be appropriate for the child’s height

• whether the selected model will be too tight or too loose

An additional challenge is that sleeping bag fit is often based not only on the child’s age, but also on their height and the construction of the specific product model.

Without a clear size chart, customers often need to contact store support or make a purchase decision with considerable uncertainty.

Solution

The Size Chart for Magento 2 module was implemented in the Slumbersac.pl store, enabling detailed fit information for sleeping bags to be displayed directly on the product page.

The module allows for:

• displaying a size chart tailored to the specifics of children’s products

• easily showing fit information based on the child’s height

• clearly presenting data in a table available to customers during purchase

As a result, parents can quickly check which size will be right for their child.

Result

After the module was implemented, the size chart became an important element of product pages in the Slumbersac store.

Key benefits:

• customers can easily choose the correct sleeping bag size

• the number of questions about product fit is reduced

• customers feel more confident when making a purchase decision

For children’s products, where safety and comfort are essential, a clear size chart significantly improves the customer shopping experience.
