His Majesty appeared to be having a whale of a time, chatting animatedly with his younger brother, Prince Edward, at the equestrian event, while Monday saw the monarch enjoy a chinwag with David Beckham.
Royal watchers were enamoured with the King's style at both events, calling him "elegant" and "suave" in his stylish suits, with many commenters mentioning the 76-year-old's use of a walking stick at both engagements.
At the Chelsea Flower Show, His Majesty used a walking stick made from an actual tree branch – a nod to his green-fingered ways and the fact he was attending a garden-centric event, perhaps.
Fans of the King raised concerns at his use of a stick, as it was something his mother, the late Queen Elizabeth II, began relying on later in her life when her mobility was compromised, but HELLO! has been reassured that the King's choice of accessory is simply that - a traditional country fair walking stick, rather than a walking aid.
Having the correct height of walking stick is vital for preserving the health of the owner. If a stick is for support, it should be held at hand height.
"The top of the handle of the walking stick should be the same height as the wrist bone," says The Blue Badge Co, which makes accessories (including walking sticks) for people with disabilities.
A walking stick that is the wrong height can cause back and shoulder problems, as well as uncomfortable joint pain, not what the King needs, with his busy schedule.
Using a walking stick
On why the royal might rely on a stick, The Blue Badge Co explains: "A walking stick can relieve pressure on painful joints and can improve your balance.
"However, used incorrectly, a walking stick or cane could increase your risk of having a fall and may lead to injuring another area of your body," they continue.

As noted, King Charles' recent walking sticks were likely ornamental, so we needn't worry about the height!
