Reviews

Love this. Bought one for work and one for homeJoanne1 - To open: Twist the lid lever above the handle anti-clockwise. First stop at approx 1/8 turn is a slow pour. The lid will come off at a 2/3 turn. The instructions are inside. The handle section is not designed to open. 2 - Review: Definitely keeps beverages hot for hours. I took one to work to replace a flask that was deteriorating. It looks sleek and modern and is very simple to use and clean. We use the second one at home to keep water hot after boiling the kettle, instead of having to re-boil the kettle every time we want a refill. It's definitely reducing our electricity use5

I’m going to get a YangVery good one. I like 5
Just what I neededAlexWanted to keep hot water on my desk to drink throughout the day. This is perfect. Twist the lid to open and pour. Twist again to remove the lid to fill. Preheat with some hot water first then refill and it lasts all day. Happy with my purchase!5

Works wellChristinaBought this for a family member who likes to have hot tea by his side while he works. He reports it is exactly what he needed. The top needs to be a great fit but is a bit tricky to open and close, especially if you have overworked wrists4

A better everyday one cup at a time

Have you had coffee or tea today? Statistically, you most likely have. In fact, these hot brews are the most consumed beverages in the world next after water. They’re a part of life that can give a silver lining to any moment. That’s why we decided to update our selection of products to make that perfect cup – from the tea infuser and the kettle to the milk frother.

Malin Ljungström, who was involved in developing the range, shares her insights. “To many, the smell of coffee and tea means well-being and a homey feeling. Since we want to improve people’s everyday, we’re offering products that make it possible for more to experience more feelgood moments at home.”

Developing things that make a difference

Malin and her colleagues dug deep into coffee and tea cultures to find out what tools people feel they can’t live without. They talked to specialists and investigated living, eating and drinking habits. “We wanted to develop items that make a difference, so we’ve focused on a few, but carefully selected products,” she states. The team cooperated with IKEA Test Lab in Älmhult, Sweden. It’s an IKEA version of a James Bond lab where prototypes are inspected and evaluated. “A couple of the things we checked were that the thermoses can keep fluids really warm for a long time. And that the glass mugs and glass pots are durable and comfortable, even though they look and feel light and airy,” says Malin.

For all tastes and different wallets

No matter how you enjoy your cup, you’ll find the things that put an extra flavour to your drink in the range. Another good thing is that there’s something for all wallets. “It’s one of our contributions to a better life at home. A way to improve people’s everyday one cup at a time,” concludes Malin.

Material

What is stainless steel?

Stainless steel is found in everything from building structures and cars to sinks and knives. It’s easy to see why it has so many uses. Stainless steel is hard and durable and has good resistance to corrosion – namely rust. It generally has a low nickel content, and for IKEA products we mainly use stainless steel that’s nickel-free. Like many other metals, it can be recycled again and again to become new, hardwearing things – without losing its valuable properties.
