    Overview

    When you have a great night of sleep, the sky’s the limit. And the Diamond Sky Queen Mattress is a perfect way to maximise your rest with deep, undisturbed slumber. Part of the Universe Bed Co range, you can experience out-of-this-world comfort with this premium sleeping solution.

    Thoughtfully designed to provide unmatched support from top to base, the Diamond Sky has three layers of foam to ensure even weight distribution, targeted support for your body, and firmness that feels just right. The gel and charcoal-infused foam layer provides a hygienic and odour-free environment, so you can rest easy every time. To top it all off, this mattress features a Coolmax cover that helps regulate heat, so you can blissfully stay asleep. This cover can be removed for extra cleaning convenience and can be securely zipped back up with ease.

    Regardless of how busy your day gets, you can always come home to your sleeping sanctuary with the Universe Bed Co Diamond Sky mattress.
    Maximum support with premium foam

    The Diamond Sky mattress features an extra thick 5cm latex-like foam with a 45D density. This gives your body additional support where you need it most, so you can enjoy a more restful night of sleep.

    All-night comfort with charcoal-infused layer

    The gel and charcoal-infused foam layer helps to reduce odours, while regulating temperature and moisture throughout the night. This 5cm thick, 35D density foam also perfectly contours to your body, resulting in a cosy and comfortable sleep.

    Sturdy base foam

    The two upper layers are supported by a durable 15.5cm base foam with a 25D density. This resilient base offers even weight distribution, cradling you to sleep and ensures you wake up feeling refreshed.

    Removable Coolmax cover

    The Coolmax cover has a unique cooling layer engineered to wick away moisture and disperse heat. This keeps the temperature comfortably consistent while you sleep so you don’t wake up feeling the heat. This cover is removable for effortless maintenance.

    Good product for the price.
    This is our second purchase for this mattress. We bought the first for the spare room and were so happy with it we bought this one for ourselves. Being vacuum packed made it easy to move and set up.

    Great Mattress. Value for money!
    I ordered this mattress at 3pm Monday and it was delivered at 11am the next morning. Due to it being vacuum packed, it was easy to carry the box upstairs. I unpacked it directly on the bed (guest bedroom). It does state allow to expand for 72 hours before sleeping on it. For the price point, I was expecting it to be average at best. But the quality of this mattress was great and my guests said it was extremely comfortable. For the price, I definitely feel it offers value for money and the speed in which it was delivered, can't be beaten.

    A good mattress for the price
    Being vacuum packed made the placement and setup easy. The mattress is quite comfortable and compares more than favourably with other more expensive mattresses that we tried; we are very happy with our choice.
