Honestly fantastic experience from start to end. Personalized support to find the right size, always quick to answer and my husband originally got the 14cm, which was a bit too high, we ended up with the 12cm and Levitex customer service was fantastic, arranged for the new pillow to be sent out and the old one we could send back (of course needs to be in immaculate condition and within the given time frame). All worked so smoothly, really really pleased! Now for the sleeping experience: 10/10, husband loves it and finds himself with way less back pain than before, it does help!
