Invest in a car seat that will last a decade!

Through July 5th, head to Diono.com where their popular Radian 3QX Car Seat is on sale for only $189.99 (regularly $379.99) – that’s 50% off and the lowest price we’ve seen!

Note shipping is only free on orders $300+, so you’ll see a hefty shipping fee at checkout. However, this is still an AWESOME deal compared to the current price of $299.98 on Amazon.

This all-in-one car seat fits newborns as small as 4lbs, and features a newborn travel wedge and an adjustable harness so infants lie in a safe position. There’s also an infant liner for extra comfort. Once kids get bigger (up to 120lbs), you can use the 12-position headrest and easily switch from rear-facing, forward-facing and booster modes.

Even better, there are anti-slip harness pads and a steel anti-rebound harness bar for added safety. Perhaps the best thing about this car seat is that its slim design makes it easy to fit three in your backseat!

Check out these reviews from Hip2Save readers…

We have Dionos for both our kids and absolutely love them. We’ve tried other brands for grandparents cars and they are the best by far. They are very heavy so not good if you have to transfer them on a regular basis but great otherwise.


Love Diono car seats for extended rear facing. My middle child was heavy & tall (95%) I was able to rear face him until he was 4 years old. This car seat is worth every penny. 🙌  My youngest (4yo) is rear facing still & will be for a while.


Agree with everyone they’re heavy but if you don’t need to move them around a lot they’re great. They can hold kids FOREVER and fit in 3 across very easy.
