Great table and chairs for kidsJudithThese were a gift for my grandchildren - I’m told they were a big hit! My granddaughter wanted to eat breakfast outside when it was 45 degrees. And she did!5
Great chair for toddlers!NancyI bought these chairs for my grandchildren. They are sturdy, look great and the kids (ages 2 and 4) love them for sitting and doing crafts or playing with toys. They are the perfect height to get in and out of without assistance for the 2 year old and safely. I had a small folding table that worked well with them, but was so pleased with the chairs I have ordered the table.5
Looks great but not sturdyNuIt looks great, I bought it thinking it would be made out of some kind of wood but it’s not. It’s all plastic, wish I knew that. My son can’t use it because it keeps falling when he tries to climb on the seats because it’s plastic.3

Sturdy and easy to cleanMgoldman89These chairs are great. Ideally, I would have liked wooden chairs; but these are so much bigger than the wooden IKEA chairs. They go great with the table from the same collection. They are very sturdy even on a shag rug. I have a super active toddler that climbs and jumps on these, and they have never fallen over. Great purchase!5
Nice looking and sturdyJeanniemastersWe bought these several weeks ago and my granddaughter and grandson love them. They’re the perfect height and bulky and sturdy but yet not heavy. The kids can move them by themselves. They are 1&4 they white looks very nice with out little table that we painted the bottom white and the top with a dark gray “almost black” chalkboard paint. Oh and they’re easy to wipe off as well.5
Tipping hazardJessica TThese chairs are tipping over with my kids in them and my kids are falling off of them way too easily. Defective and dangerous1

Our take on plastic

Plastic is a key material for IKEA, and remains so going forward. It is strong, durable, lightweight and versatile. It is a main component in a large amount of our products and has a wide variety of applications from surface materials such as paint and foil, to screws and shelf pegs. There is a lot of valid concern regarding how plastic impacts the environment and at IKEA we take this very seriously. As part of our larger circular journey and transition from virgin fossil based material, we are working hard to change all plastic in our home furnishing products to plastic made from recycled and/or renewable raw materials.

Sarah Pattison is an engineer at Children's IKEA who has worked with improving the MAMMUT series. For example, today the tables contain less plastic than when they were introduced. "Thanks to new technology, we could scale away some plastic inside the table top without compromising on its stability. This change hasn’t affected its look, but it means we use less material."

High demands on safe plastic

All MAMMUT parts are made of polypropylene, a plastic particularly suitable for children’s products. "When children play, their skin often comes in contact with things and that’s why the plastic we use always meets the world's highest set chemical requirements by a good margin,” says Sarah. But plastic is slowly broken down by the sun's UV rays, which can affect both color and quality when using the furniture outdoors. "When we understood that children like to carry the furniture outdoors, we reinforced the plastic with UV protection, which of course also complies with our chemical requirements."

Safety tests every year

The furniture also goes through annual safety tests. New knowledge about materials and safety constantly surfaces and needs to be adapted to. So why has MAMMUT survived for so long? "I think it's the cheerful colors and the appeal of shapes that feel like they came out of a comic book", says Sarah. "My daughters have used them for countless teatimes and building play forts over the years."

Only recycled or renewable plastics

Plastic is most commonly derived from oil and gas, which are non-renewable fossil sources. These sources do not renew themselves and will eventually be depleted. Our ambition is that by 2030, all plastic used in our products will be based on renewable or recycled materials. Renewable plastic is made from materials such as vegetable oil, corn, wheat grain and sugar cane. Recycled plastic allows us to give a second life to non-biodegradable products such as PET bottles that would otherwise end up in landfill. Using recyclable sources also lessens our dependency on oil as a raw material. Currently more than 40% of our plastic products are based on recycled and renewable materials and our aim is to reach 100%. As we add products made from recycled and renewable materials to our offer, we hope to inspire other companies to do the same.

Phasing out single-use plastics

Single-use plastic items pollute ecosystems if not disposed of responsibly. As part of our commitment to people and the planet, all single-use plastic products from the global home furnishing range were phased out in 2020. This includes items such as plates, cups, and plastic straws offered in our restaurants, bistros, and cafes. These were replaced by disposables made from 100% renewable sources.

PET and PP our most commonly used plastics

Polythylene terephthalate (PET) and Polypropylene (PP) are durable, hygienic and shatter-resistant plastics. They absorb very little water and have good chemical resistance. Both PET and PP can be reused and recycled, which reduces waste and gives the product several lives through use and reuse. PET is the most recycled plastic in the world and can be used for many different purposes such as plastic bottles and containers for packaging food and beverages as well as for personal care products, pharmaceuticals and many other consumer products. At IKEA we mainly use recycled PET in boxes, filling material for textiles and kitchen front foil. PET is approved by health-agencies as safe to use for food and beverage. IKEA uses recycled PET that is post-consumer based, which means it is based on collected and sorted PET bottles.

Clean and safe

IKEA takes product safety very seriously and all products are tested and comply with the strictest possible laws and safety standards on all IKEA markets. Customers should always feel confident that products bought at IKEA are safe and healthy to use. IKEA wants to minimize or totally refrain from the use of chemicals and substances that can be harmful to people and the environment.

Together, we can do more

Our journey towards only using recycled or renewable plastic will take some time and require new ways of doing things, but we are determined to take responsibility and find new solutions. We want to give our customers the possibility to choose products made from more sustainable materials that can be recycled again one day. Together, we can make a big difference!
