    Who it's best for

    • Renters who cannot install permanent curtain poles
    • Parents of babies and toddlers for daytime naps
    • Holidaymakers staying in bright or hot accommodation

    Who should avoid it

    • You want a permanent, high-performance thermal insulation solution
    • Your windows are larger than 99 x 130 cm

    Overview

    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.

    Key features

    • Suction cup attachment for tool-free fitting
    • Adjustable size via Velcro-style fastenings
    • Lightweight and portable for travel
    • Complete blackout fabric construction
    • Universal fit for windows up to 99 x 130 cm

    Real world performance

    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.

    Energy saving potential

    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

    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.

    Running costs

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

    Pros

    • Highly effective at blocking external light
    • Non-permanent, making it perfect for UK renters
    • Comes with a convenient travel storage bag
    • Helps keep rooms noticeably cooler in direct sun

    Cons

    • Suction cups can fail if glass is not perfectly clean
    • Slight light bleed at the edges of the window frame
    • Not intended for long-term permanent use

    Frequently asked questions

    Will this help keep my house warm in winter?

    Its primary design is for blackout and summer cooling; it offers very little thermal insulation against the cold compared to dedicated draft-proofing or heavy curtains.

    Does it work on double-glazed windows?

    Yes, it attaches to any smooth, flat glass surface, including modern UK double glazing.

    Can it be adjusted for smaller windows?

    Yes, it features integrated fastenings that allow you to fold and secure the fabric to fit smaller frames.

    Is it machine washable?

    No, it is generally recommended to wipe clean with a damp cloth to protect the blackout coating and suction attachments.

    Final verdict

    3.8 / 5

    This is an excellent temporary solution for renters or travellers needing to block light and manage solar gain in summer. While not a primary insulation tool, it offers a cost-effective way to keep south-facing bedrooms cooler during heatwaves without expensive installs.
