Me and my partner was suffering with sore and stiff joints when we woke up in the morning, so haven had the same pillows for a number of years we thought we would upgrade and spend a little bit more money on something to which makes us sleep better. We follow Levitex on TikTok and watched a number of videos before making a purchase to make sure we were buying the correct pillow. I’m 6’2 and my partner is 5’11, I got an XL and he got L. We are both side sleepers, and Levitex instructed us to sleep in the “dreamer” position with a pillow between our legs and BOY this works a dream (no pun). We slept like babies and wake up with zero pain/aches. Would recommend. Thanks Levitex. Also fantastic customer service! I was unsure at first if I’d purchased the correct pillow, but Levitex are on hand for advice via social media to assist with any concerns. No regrets with my purchase.
