Tommee Tippee Sleeptight Portable Blackout Blind Review

The Tommee Tippee Sleeptight is a medium-sized (99 x 130 cm) portable blind featuring a star and moon print. It uses suction cups to adhere directly to window glass, making it ideal for nurseries, guest rooms, or travel. The adjustable fastenings allow it to fit various window sizes smaller than its maximum dimensions, and its lightweight polyester construction makes it easy to pack into its included travel bag.

In testing, the suction cups perform best on clean, grease-free glass; if the window is dirty, they can lose grip overnight. The 'blackout' capability is high, though light bleed can occur around the very edges if not pulled taut. Its portability is its strongest suit, though the fabric can feel a bit thin compared to premium permanent blackout solutions.

From an energy-saving perspective, this blind acts as a passive cooling tool. By reflecting a portion of solar radiation before it hits internal surfaces, it can help maintain lower room temperatures during UK summer peaks, potentially reducing the need for electric fans or portable AC units. However, it offers negligible heat retention in winter as it does not create an airtight seal to prevent convection currents behind the fabric.

Installation takes minutes: simply moisten the suction cups and press them firmly against the glass. No tools or drilling are required, though it is vital to ensure the window is thoroughly cleaned first to prevent the blind from falling.

Zero. Aside from the initial £24.99 purchase price, there are no ongoing costs. The product is durable enough for repeated seasonal use.
