I bought super king size. Brilliant sizing with adjustable straps for different thicknesses of mattress. After leaving for the allotted time I was dying to try it It was well worth the wait. It was so comfy, very supportive no matter your size or weight, I was always an early riser due to back pain but that’s no longer an issue I don’t want to get out now I’m so comfy. I would definitely recommend this make **
