The Winkle took us a while to get used to as it’s much firmer than we expected. My partner has always had firm beds and this one he loves, it’s made an incredible difference for him. He’s 6’6 and has always struggled with back problems and once we got our bed his back issues changed phenomenally. He still gets a bit sore every now and again but no where near as bad as before. As for me it’s too firm for me as someone who has always had soft beds and I think my body does prefer them. It doesn’t give me any issues though but would love it if it was a bit softer.
