16 Luxe Gifts Perfect For a 40th Birthday

Ember Temperature Control Smart Mug ($110, originally $140)

Give the gift of enjoying hot coffee and tea until the very last sip with this temperature control mug. It's Amazon's bestselling mug for good reason. It offers 90 minutes of heat and defaults to a temperature of 135 degrees Fahrenheit but can be adjusted with the accompanying app — and it remembers the last setting. It wakes up as soon as hot liquid is poured into it and goes to sleep using motion detection.
