Joie i-Spin 360 Review: The Rotating i-Size Seat Parents Keep Buying
A seat that turns to face the door, fits from birth and stays rear-facing until your child is about four. It has been on sale since 2019 and is still one of Joie’s best sellers. A European crash-test lab rated it highly, a Mumsnet parent tester called it the most usable seat in their round-up, and 132 Argos buyers give it nearly full marks. The catches are its 13.9 kg weight and the fact that it fits with ISOFIX only.
Where the reviews line up
The evidence comes from three different places: the crash and usability test run by the German motoring club ADAC with its European partners, a hands-on parent test published by Mumsnet, and 132 shopper ratings at Argos. They agree on more than they disagree.
It protects well, especially from the side. ADAC gave it an overall 1.8 (German grades run from 1, best, to 5) with 1.7 for safety, and listed a low injury risk in a side impact first among its strengths. The spin is the reason people buy it. Mumsnet’s tester says the one-handed rotation, recline and harness adjustment made it “the best seat we tested for all-round usability, comfort and feel”, and a shopper comment on Latest Deals says the rotation saves your back.
The criticisms agree too. It is heavy and bulky. ADAC called the weight “very high” and said it takes up more space in the car; Mumsnet found it smooth with nothing to grab when carrying it. The support leg is fiddly: Mumsnet reported “some issues with the floor leg fixture”. And it fits only with ISOFIX, so a car without ISOFIX points cannot take it at all.
Our view: if you have ISOFIX, a car on Joie’s fit list and plan to leave the seat in one car, it is a well-proven choice, and at about £175 it is far cheaper than its £250 list price. If you swap seats between cars often, have a small car, or want a seat you can also fit with a belt, look at something lighter.

Before the review: which i-Spin 360 this is
Joie sells several seats with similar names. This page covers the i-Spin 360 (birth to about four, 40–105 cm), which Joie’s UK site lists as in stock “from £200” on 13 October 2026. It is not the cheaper i-Spin 360 E (from 61 cm), the new i-Spin 360 Compact (61–105 cm, 11 kg, no newborn insert) or the European i-Spin 360 R, which the Austrian motoring club ÖAMTC tested in autumn 2023. Joie itself recommends the i-Spin 360, not the Compact, if you want a spinning seat from birth.

ADAC
Who they are: ADAC is Germany’s motoring club. It crash-tests child seats with Austria’s ÖAMTC, Switzerland’s TCS and Stiftung Warentest, using seats bought from retailers, sled tests in a VW Golf VII body at its Landsberg centre and a published weighting (safety 50%, operation 40%, ergonomics 10%, with chemicals able to fail a seat outright). It is the most thorough test result available to the public, though the test of this seat is now seven years old.
The consortium tests every seat the same way: a frontal crash at the Euro NCAP pulse, a side impact against a fixed door, then handling, misuse risk, fit in the car and chemicals. The i-Spin 360 came out well. Its strengths, in ADAC’s order, are a low injury risk in a side impact, very good padding, plenty of room for the child and very low levels of harmful substances. That last point earned the best possible 1.0.
Its weak points are the practical ones: a “very high” weight of 13.9 kg, a seat that takes up a lot of room in the car, a restricted view out for the child and leg support that is “not optimal”. Stiftung Warentest, one of the partners, scored it 84/100 and third of 19 in April 2020, according to a retailer’s summary. Its newer European sibling, the i-Spin 360 R, scored 2.4 overall in ÖAMTC’s autumn 2023 test, with a 0.9 for side impact but 3.1 for operation. That seat is not the one sold in the UK.

Who they are: we could not find a published profile for Sam; the test was chosen because it is the most detailed UK hands-on review we found, covering fitting, school and nursery runs, longer trips with twins and cleaning. Mumsnet says its testers use products for at least two weeks and it earns affiliate commission, so read it as informed parent testing rather than lab data.
The tester’s verdict is that this was “the best seat we tested for all-round usability, comfort and feel”. Fitting was easy: the ISOFIX arms slot “right into place straight out of the box”, with an indicator on the base to show it is on correctly. The spin, the recline and the harness height all work with one hand, and the seat reclines while fitted. The cover goes in the washing machine at 30°C.
The complaints are specific. The support leg drops down automatically and is hard to push back up. The smooth shell has nothing to hold when you carry it. The straps need a hard pull to tighten and the release button is hidden under padding. Two of these seats may not both spin in the same car, and lifting a sleeping child out usually wakes them. Mumsnet gives no crash-test figures of its own.

Who they are: Argos’s star ratings are written by its own shoppers on its product pages; we could not read its review policy, so treat them as unverified customer experience and weigh the pattern across many reviews rather than individual comments.
This is the largest UK buyer sample we could read. An average of 4.89 from 132 reviews is a very high score. Argos’s page needs JavaScript to show individual reviews, so we could read the score and count but not the comments, and we could not see whether Argos or a marketplace seller is selling it.
Other buyer evidence points the same way but is thin. Galaxus in Austria shows 4.8/5 from just 13 ratings, and Kiddies Kingdom lists 33 reviews with no score visible. A shopper comment on Latest Deals sums up the appeal: the rotation “is an absolute must if you don’t want to get a bad back”.

What holds up
- Rated 1.8 overall by ADAC, with a low injury risk in a side impact.
- Rear-facing from birth to 105 cm, about four years old.
- Spins 360° to face the door, and the release works one-handed.
- ISOFIX with an indicator, so it is hard to fit wrongly.
- Six recline positions, adjustable while fitted.
- Very low harmful-substance levels in ADAC’s test (1.0).
- 4.9/5 from 132 Argos buyers; about £175 against a £250 list price.
What people complain about
- Heavy at 13.9 kg, with nothing to grip when carrying it.
- Bulky: ADAC says it takes up more room in the car than most.
- ISOFIX only. No seat-belt fitting.
- The support leg is awkward to retract.
- Straps need a hard pull and the release is hidden under padding.
- Two seats may not both spin in a narrow car.
- ADAC’s test dates from 2019; no newer public test of this exact UK model.
Who it actually suits
Buy it if your car has ISOFIX and is on Joie’s fit list, you want one seat from birth to about four, and you would rather turn the seat than lean into the car to lift a baby. It is a good choice for parents with bad backs, and in a family car it can stay rear-facing for as long as the experts suggest.
Look elsewhere if your car has no ISOFIX, you move the seat between cars every week, or you have a small car or need three seats across. In those cases a lighter seat, or one with a separate base, will be easier to live with. If your baby has already outgrown an infant carrier, Joie’s lighter i-Spin 360 Compact (from 61 cm, 11 kg) is worth comparing.
What we could not check
- Which? scores. Which? has tested this seat (first review October 2019, last checked August 2026), but its crash, fitting and overall scores and any Best Buy status are behind a paywall. We have not quoted them.
- A recent test of the UK model. ADAC’s test is from October 2019. The 2023 ÖAMTC test covers the i-Spin 360 R, a European sibling, so we have not treated its scores as this seat’s.
- The Argos seller and reviews. Argos showed its score, count and price but not who sells the seat or the review text. Argos also hosts marketplace sellers.
- Mamas & Papas stock. Its £250 page said both “Less than 20 in stock online” and “Out of stock instore and online”.
- The Costco price. Costco’s page carried a £109.99 price in its metadata only, with no visible price or stock. We have not used it.
- Which R129 version. Joie’s international page and its UK shop listing say R129/02. Joie’s UK page does not give a number.
- Your car. Joie’s fit list includes the Ford Fiesta and Focus, VW Golf and Polo, Vauxhall Corsa, Nissan Qashqai, Kia Sportage and Tesla Model 3 and Model Y, but the seat-by-seat symbols did not come through when we read it, and Joie says the list is guidance only. Check your car against the list and, if you can, try the seat in a shop first.
- Stiftung Warentest’s 84/100 comes from a retailer’s summary on Galaxus. We did not read the original.
- The videos were confirmed by their watch URLs and titles appearing in two separate search listings. We did not open them, and the listings did not name the channels.
