Wallpaper - Medallion Trellis, Seafoam

Our Medallion Trellis wallpaper in seafoam brings a rhythmic, architectural quality to the wall through interlocking arches and delicate dotted details. Rendered in a soft seafoam turquoise across a crisp white ground, the symmetrical lattice balances classical structure with an airy, decorative lightness. What we particularly like is how the fine line work and gentle watercolour-inspired character prevent the geometric repeat from feeling rigid. Like all our wallpapers, this design is made to measure to your exact wall dimensions on PVC-free paper with a subtle surface structure.

In the room

Because the trellis repeat is orderly and balanced, we find it works beautifully across both open and more compact living spaces. In a bedroom, dressing room or powder room, wrapping all four walls creates a tailored, enveloping feel without overwhelming the space. The crisp contrast between the seafoam and white keeps the overall atmosphere fresh and open, making it equally well suited to a feature wall behind a bed or sofa in a living room. For hallways and staircases, the repeating arches offer an elegant sense of direction and visual continuity.

Styling it

We like pairing this design with interiors that blend classic charm and contemporary ease. Painted woodwork in fresh off-white or soft muted tones complements the crisp background, while natural warm timber furniture introduces grounding warmth against the cool seafoam geometry. To keep the focus on the rhythmic lattice, we suggest keeping larger upholstery in understated neutral fabrics, bringing in decorative accents through glazed ceramics or subtle brass hardware that echoes the transitional character of the motif.

Colour combinations

The design centres on a cool, gentle seafoam turquoise set against a clean white backdrop. In the surrounding room, we would look to warm off-whites, pale stone, and soft chalky greys on adjoining walls and woodwork to maintain a bright, cohesive look. If you want to introduce subtle contrast, deep petrol blue, slate, or warm sand tones in cushions, throws, or cabinetry pick up on the maritime softness of the seafoam without competing with the pattern.
