    After trialling a Simba and owning a Leesa, the R90 Sleepkit has been a big step for me. In short, the R90 is more comfortable and helps with my sleep. It makes complete sense that a mattress tailored to your body shape and sleeping style would be better and now I can testify to this from direct experience. I learned about the R90 via Nick Littlehales’ terrific TEDxNewcastle talk which I can also recommend!\n- Herb Kim
