CASE STUDY

Matt Sleeps x Flatline Agency

Matt Sleeps has built one of the most recognisable visual worlds in the Dutch sleep market. A deep blue palette, the iconic “bed in the water” concept, and a mattress that commands attention in every frame. As the brand’s ambitions grew, so did the demand for campaign imagery that could match that standard: fast, consistent, and at scale.

What happens when a fashion brand outgrows its setup

The challenge — Keeping up with a brand that moves fast

Matt Sleeps needed campaign-ready visuals for two simultaneous campaigns: Holiday Pay & Evergreen. Expired model buyouts created both urgency and legal risk. Traditional photography meant weeks of planning, reshoots, and usage rights negotiations. None of which fit the pace the brand was moving at.

The visual world of Matt Sleeps is precise and non-negotiable. The blue palette, mattress proportions, quilted top surface, logo placement. Every one of these details defines the brand. Any solution had to protect that consistency while moving dramatically faster.

Flatline's approach — Build the workflow, not just the assets

Rather than solving the immediate problem with a one-off shoot, Flatline built a structural solution. A purpose-built AI image generation workflow, engineered from the ground up around the Matt visual world. Every element was defined from the start: brand references, campaign messaging, and visual components that could never be compromised.

The models themselves were created entirely from scratch. AI-generated, but with no compromise on quality. The result is a repeatable, scalable production system that gives Matt Sleeps full creative control without the cost, complexity, or legal exposure of traditional photography.

THE PROJECT

Input & prompt engineering

01 — Input Everything starts with a clear brief. We define the model specifications, brand references, campaign messaging, and visual components that are locked for the entire workflow. This becomes the single source of truth that guides every step that follows.

Parallel generation at scale

02 — Prompt Engineering Based on the brief, we engineer structured AI prompts. Each prompt is built to respect the Matt visual world: the blue palette, the water concept, mattress proportions, and all brand-critical details. Nothing is left to chance.

Review, refinement & delivery

03 — Generation The prompts are executed simultaneously, generating multiple visual outputs in parallel. Angles, close-ups, wide shots, and model variations — all produced in minutes. Dozens of campaign-ready options, ready for review.

04 — Review & Selection All outputs are reviewed and the strongest visuals are selected. Adjustments are flagged and iterations are executed rapidly within the same workflow. Client feedback is captured and addressed throughout this stage.

05 — Refinement Selected visuals are refined and finalised. Cropping, colour grading, format adaptation, and meticulous brand consistency checks are applied to every asset before moving to the next stage.

06 — Export & Delivery Final assets are exported in all required formats and organised into a structured, clearly labelled library — ready for immediate deployment across all channels and platforms.
