  1. Meg

    This is simply the most comfortable bed you can imagine. The dual mattress prevents any transmitted movement from the other person and it is very stable so no chance of any problems with motion sickness.
    Great service from this company as usual -would never chose to have an ‘ordinary’ bed again!

  2. kim

    Excellent , fast service . Good quality mattresses , the only mattress I can sleep on without getting back ache . Love my bed ! An no problems if there’s a weight difference between you & your partner with the separate mattresses .

  4. Justin Cork

    Amazing mattress to replace our last aqua star water bed which had given up the ghost. Ordered and delivered the next day, well packaged and the quality of the waterbed is superb, The ST5500L is incredibly supportive and like laying on mud. Nearly bought from another German company but they’re customer service and delivery is awful so glad I chose aqua glow

  5. Meg

    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.
