Fun to read this restrictive comment: "The product being for an elderly person, it has the advantage of not blocking the feet unlike other models." I think age certainly contributes to some slower blood flow more difficult, but I know many young people who have the tips of frozen feet (that's why besides our arrières- grandparents slept with a night cap for the blood back through the brain was cooling - heating did not exist or little -. and arrived "cold" feet Putting a cap, the blood does not cool ). So, you can replace the Chancellor with a cap (heated if you like - lol). Sweet, large, nice, correct in temperature levels, this is a good choice for those who love to see his series on television, feet on heating rather than snow (: o).
