Designed as a functional and decorative solution, this high-density sponge wedge fits precisely into 90-degree angles, whether between seat cushions, against an armrest, or in a room corner. Measuring 68cm by 33cm by 25cm, it provides a sizeable filler that stays in place, improving seating comfort and tidying your living space. Available in a selection of five colours, each featuring surface embroidery, it combines practicality with a tailored finish.
Features and Construction

This pillow is built around a simple, effective shape and construction aimed at solving specific furniture fit problems.
Material and Build
The pad is filled with polyester fibre, a common cushioning material that provides a soft yet supportive feel. The outer cover features an embroidery weaving craft, adding a decorative textile detail to the surface. This construction focuses on providing volume and a padded structure rather than specialised ergonomic shaping, making it a practical filler for general use.
Size and Practical Fit
The key specification is its dimensions: 68cm in length, 33cm in width, and 25cm in height. This creates a substantial triangular wedge. The 25cm height is particularly relevant for filling deeper gaps between cushions or providing noticeable lumbar support. The 68cm length allows it to span a significant portion of a sofa seat, while the 33cm width gives it stability. Its geometric shape is its primary functional feature, designed to lodge securely in right-angled spaces.
Uses and Placement

The triangular design dictates its primary applications around the home, focusing on improving comfort and functionality.
Event or Professional Use
For settings requiring temporary additional seating support or gap management, such as in a waiting area or during an event, the pad can be quickly deployed. Its neutral colour options like grey, black, or lake blue can suit various decors. The simple shape makes it easy to position and remove as needed, providing a basic level of extra padding without complex setup.
Everyday Home Use
In daily use, place the pad vertically between your sofa's back and seat cushions to prevent remote controls, phones, or books from slipping down the gap. Alternatively, use it horizontally along the armrest to create a softer arm prop, or wedge it into the corner of a sectional sofa to define the seating area. It can also serve as a lower back support pillow on a chair or bed due to its supportive height.
Benefits and Buying Value

This product offers value through its specific shape solving a common nuisance and its straightforward, reusable design.
Reuse and Low Maintenance
As a single, solid pillow, it requires minimal maintenance; occasional spot cleaning of the embroidered fabric is typically sufficient. There are no moving parts or complex mechanisms. Its durability comes from its simple construction—a fabric cover with fibre filling—making it a long-lasting item for gap-filling purposes that can be moved and reused in different spots as needs change.
Why Choose This Product
Choose this triangle pad if you need a functional solution for sofa gaps or corner support with a defined size of 68x33x25cm. Its value lies in its specific dimensions and shape, which are suited to this task, and the choice of five colours allows it to blend with your existing decor. It provides a straightforward, single-purpose item focused on improving comfort and tidiness in seating areas without unnecessary features.
