  1. Esther Barker

    I ordered this mattress during the afternoon, and it arrived next day, at 9.00 am! With free delivery, I was very impressed. The mattress is exactly as described, and is now on our bed giving us beautiful sleep every night. I would highly recommend Aquaglow and have no hesitation buying from them again. I also ordered the 4 year conditioner pack, which again, arrived quickly.

  2. Matt

    Very happy with the mattress. And more than happy with the service – you were helpful when it turned out I’d stupidly ordered the wrong size! Super fast delivery too. Thank you.

    Fantastic Service called mid morning on the 29th December for new mattress as old one had finally died lol, and it was delivered before 9am the next day.Staff was so friendly and a joy to deal with.

  9. Gabriela

    Fantastic service. I live in Cyprus, I ordered the mattress on Sunday evening, and arrived to me on Wednesday. My previous mattress was from a different company, different size and shape, so I had to order the foam locally. Adam helped me to find the right size for my bed, and was very kind to answer all my questions. Thank you!

  10. Gillian Sloan

    Purchased super king size mattress to replace our old that was leaking. Services was second to none, very helpful over the phone when I wanted to check some details, arrived well packaged and very quickly. Installation was easy, as I purchased pump at same time to empty old one. Only issue I had was the very strong smell which I hadn’t had with any of our other mattresses, but I called up and they suggested that I might have used too much hot water which is not recommended, but I needed to sleep on it that night and if you’ve ever tried sleeping on a cold water bed, it’s pretty miserable, any smell went away after about a week, I left the covers back daily and it was bearable, if I left covers on it the smell was worse when you pulled duvet back at night. None of this was the companies fault, I was extremely happy with the service and product and shall most certainly use them again in the future.

    Purchased this mattress when our existing one began leaking. Despite the UK being in Covid Lockdown and all businesses closed, Aquaglow were available on the telephone and ensured that the new mattress was delivered Next Day. Brilliant Service.

  13. Meg C

    We have used Aquaglow now for over 20 years and have never been disappointed with the service. We recently replaced our deluxe twin mattresses for a soft sided waterbed and they arrive promptly and are giving us a great nights sleep, thanks again.
