    The mattress topper and comforter are absolute magic. It feels like I’m sleeping on a fluffy cloud!\n- Conrad Norton\n

    The travel mattress was a savior for my 6 week stay at the Hostel in Bozeman. The Hostel provided an unfavourable sleep environment, but I slept very well. I’m extremely happy with the investment. Thanks for all the help.\n- Tim Walter

    Received the first shipments and they are fantastic. Really love the mattress topper, it’s exactly what I needed. Thanks for everything you did to make this order happen and for all your work to create the shipment. I am very grateful to you and Nick for all the help. \n- Philip Horwitz

    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
