Triangle cushion pillow with high-density sponge furniture foam filler available in five embroidery colours including red, grey, black, lake blue and peach measuring 68cm by 33cm by 25cm for sofa armrest, reading nook, or floor seating support.
High-density sponge triangular wedge cushion with embroidery finish in five colours for sofa and floor support

This triangular cushion is designed to fill angular gaps in your seating arrangements, providing firm support where standard pillows fall short. Its core is built from high-density sponge furniture foam, a material chosen for its ability to hold a defined wedge shape under regular use. The 68cm by 33cm by 25cm dimensions create a substantial piece that fits snugly into sofa corners, serves as an armrest wedge, or acts as a supportive floor pillow for reading or lounging. The cover features an embroidery weaving technique, adding a crafted, textured look, and is available in a selection of five colours: red, grey, black, lake blue, and peach. Sold as one pillow per order, it is a straightforward solution for adding targeted comfort and a decorative accent.
Features and Construction

The pillow's design focuses on providing structured support through its materials and shape. The triangular form is specifically sized to address common gaps in living spaces.
Material and Build
The internal structure uses a high-density sponge furniture foam core. This foam is firm, helping the pillow maintain its triangular wedge profile rather than collapsing flat. Surrounding the foam is a layer of polyester fibre filler, which adds loft and softens the feel around the firm core. The outer cover is made using an embroidery weaving craft. This technique creates a finished surface with visual texture and detail, differentiating it from plain woven or printed fabrics. The available colours—red, grey, black, lake blue, and peach—are integral to this embroidered finish.
Size and Practical Fit
The pillow measures 68cm in length, 33cm in width, and 25cm in height. These dimensions produce a pronounced wedge shape. The 68cm length allows it to span a significant portion of a sofa's corner or armrest. The 25cm height provides substantial back or arm support when placed vertically. This size makes it suitable for adult seating support in living rooms, bedrooms, or reading nooks where extra lumbar or side comfort is needed. Its triangular geometry allows it to fit precisely into 90-degree corners that rectangular cushions cannot fill effectively.
Uses and Placement

The triangular shape opens up specific use cases that leverage its angular design. It functions as both a comfort aid and a decorative element.
Event or Professional Use
For temporary seating arrangements at events, in waiting areas, or in photo studio settings, the cushion can provide defined back support on benches, floors, or makeshift seating. Its firm foam core ensures it doesn't flatten quickly under weight, maintaining guest comfort. The embroidery finish offers a more finished, decorative look compared to plain utility cushions, making it suitable for environments where aesthetics matter. The five colour options allow for coordination with event themes or brand colours when multiple units are used.
Everyday Home Use
In the home, the primary application is as a sofa corner wedge. Placed in the angle where two sofa sections meet, it fills the gap, providing lower back support for someone sitting in the corner. It can also be used vertically against a sofa armrest as a padded arm or side support. On the floor, it serves as a supportive backrest for reading, gaming, or watching television. The embroidery detailing and colour choices—red, grey, black, lake blue, peach—allow it to function as a decorative accent pillow when not in active use for support, blending with room décor.
Benefits and Buying Value

The value of this product lies in solving a specific spatial problem with a dedicated design, using materials chosen for shape retention.
Reuse and Low Maintenance
The high-density foam core is selected for its durability and shape retention, suggesting the pillow can be used repeatedly in its support role without losing its fundamental wedge structure. The embroidery-finished cover is designed for visual appeal and texture. Maintenance involves simple spot cleaning; the source does not provide specific washing instructions, so a cautious approach is recommended to preserve the coloured embroidery. The design has no moving parts or complex assemblies, contributing to straightforward, long-term use.
Why Choose This Product
This pillow is chosen for its specific triangular shape and firm core, which are not always found in decorative throw pillows. It addresses the practical need for support in angular spaces rather than just providing soft decoration. The combination of a high-density foam core for structure and polyester fibre for surrounding loft offers a balance of support and cushioning. The embroidery craft on the cover provides a distinct textured finish compared to standard printed fabrics. With five colour options, it offers a degree of choice to match existing home furnishings without requiring custom orders.
