    Thanks! We love our diono and have been on the hunt for another so we don’t have to move it between cars!

    • Amber (Hip Sidekick)

      Oh perfect! You’re so welcome, Chelsea!

  2. Alexandria

    Anyone know if this deal is a one time thing or it’s uncommon?
    Trying for our second baby. I don’t want to buy too prematurely but I really want this deal

    • holls

      This is an amazing deal and these car seats last 10 yrs where a lot like graco may only last 7 years. We have the 3RXT and love it. You can get a deal on just the car seat on occasion through sites like zulliy when they update models so that car seat in a year or two will sell for 150-200. I’m assuming they may be discounting this stroller and that’s why they are offering this deal.

    • Ingrid

      We’re also trying for our second and bought this deal! Too good to pass up.

    • Illinois

      I wonder as well, we are in the same spot
      Trying but not pregnant yet

      Baby dust to you

    • L

      This looks to be a single stroller. Not sure how old your first born is, but you might want to think about if you would rather have a double stroller? The deal does look amazing, but you might not use the stroller as much as you think you would? I am not trying to offend, just help you decide!

      • Alexandria

        Thanks everyone!!

        Baby dust to you, too, Illinois. 🙂

        L, I wasn’t even thinking about that. Very good point. Thanks!!

  3. Kristin

    This was their warehouse sale. They usually do it every 1-2 years! So not very common. They gave small sales, but deep discounts are rare. Usually it’s done at their ware house, but this year they moved it to online.

  4. MrsO

    Best seats ever!

  5. Anil

    Guys, Is this good for new born baby ?

    • holls

      Look up the car seat you are interested in on car seat for the littles website. They do a great job of testing car seats and explaining height and weight limits. This is important because every one has different size babies and so car seats meet their needs differently. Personally, I used a traditional baby seat for the first year and transitioned to the diono at the age of one.

    • Ashley

      Newborns don’t fit in this seat as the the lowest harness slot would be too high…also most cars aren’t big enough for this seat to fit at the newborn angle

      • Jess

        I think it depends on the newborn as many review websites state that it can be safe for some newborns. As to it fitting in all vehicles, I can happily attest that it will fit in just about any minivan rear-facing. It also fit in my small SUVs but not in my compact car when rear-facing. I would definitely check your car before buying if you want to rear-face 🙂

        • Joanna

          Has anyone received a shipping notification yet?

      • Becky

        It can be used for newborns, 5lbs and up. We used our with our newborn and he did just fine.

  6. Janine

    What an awesome deal!!!

  7. Hello

    Is this a smaller company? I’ve never heard of them

    • Nikki

      They are not necessarily small but high end/boutique. Solid steel in the back not plastic. They have been around since 1999 and were formerly called sunshine kids. I have seen them in person only at babies r us and buy buy baby they are not sold at Walmart or anything more mainstream/nationwide so it might be why you haven’t heard of them.

    • Lindsey

      Best car seats ever! I have 2 convertible car seats & they don’t expire for 10yrs. I was able to rearface my children to 4 yrs old. They are also one of the most narrowest carseat on the market. Some cars can hold 3 car seats in a row.

      • lisabestboyer

        Good for you Lindsey! They are the safest rear facing for as long as possible!

        I would have snapped this up to but my babies are teenagers now, lol

    • Amanda

      They used to be sunshine kids but changed their name to diono

  8. Ashley

    I would have totally jumped on this deal for my third. But I bought during the target trade in event. I got the 3rxt for $205 so in this deal- it’s like getting the stroller for $95 or so. I can’t speak for the quality of the stroller as I only have had Britax strollers but I am very pleased with the seats- I have 3 across and I love having my third row folded down for more trunk space during travel. My oldest two don’t need strollers so this would have been a nice update to our almost 7 year old stroller. I would say it’s a good deal for sure.

    • Amber (Hip Sidekick)

      Thanks so much for sharing your experience, Ashley! Good to know!

    • Molly

      We have the stroller and it is awesome! Wish this deal had been around before we bought the stroller.

  9. A.Lee

    I have owned three of the seats and will never recommend anyone to purchase again. When taking the cover off to wash the foam that is glued along the inside head wings and body has fallen off and broken within a year of purchase. Since the seat is so expensive, I expected customer service to apologize and replace. They told me to HOT GULE the foam back on. A google search found that this is a problem that others have had and that is why they treated it so casually. So heads up that these seats for me have not lasted 10 years and they are ok telling me to trust hot glue for my child’s life in event of a crash. I asked them how they would replace my son in the event that the hot glue didn’t work…

    • Amber (Hip Sidekick)

      Oh darn! That does sound frustrating. Thanks a bunch for taking the time to comment. We sure appreciate the feedback.

  10. Kate

    This is an amazing deal! These seats are the best seats- we have 6 of them! I just retired my daughter’s seat I got in 2009. I like that they are narrower than other seats so they fit 3 across in a standard size car/suv. They also fold up for travel. My husband had one on his shoulders like a backpack and the other he carried with one hand. No need to pay for those suitcase carts at the airport. They are made so much better than Graco and other brands (they’re are equivocal to Britax IMO).

    • Liza (Hip Sidekick)

      Thanks so much for taking a moment to share your experience with these seats, Kate! Sounds like they’ve been awesome for your family!

  11. jess

    How long is this sale good for?

    • Liza (Hip Sidekick)

      Their site doesn’t share an end date for the sale, Jess, so you may want to purchase soon if you’re interested!

  12. Mama San

    Anyone know the difference between all 3 models?

  13. Tisy

    Recommend to my friend, she has 2 baby!!Thanks

    • Amber (Hip Sidekick)

      That’s great, Tisy! You’re welcome!

  14. Faith

    I love these seats! We have three of them so they fit across the back seat of my sonota. They were the only brand thin enough to fit the across. But they are are also the most sturdy car seat I’ve ever felt. They are super heavy to move, but I like knowing they are solid. We love them. Super easy to use and they last ten years!!

  15. Kristin

    We are on year 5 of our seat and it’s in great condition. Have taken off the cover several times to wash and looks new. Also had a problem
    Converting our seat to a booster and let the company know it wasn’t working correctly. They sent me their $100 booster for free! Great company.

  16. Micah Tjeerdsma

    Is there a coupon code for this? Thanks!

    • Amber (Hip Sidekick)

      No code is needed. It should apply automatically for you when you add the items to your cart. Hope that helps!

  17. Marcia

    Looks like the 2AX is no longer offered with free stroller.

    • Amber (Hip Sidekick)

      Bummer! You’re right. Thanks for letting us know!

  18. Joanna

    Has anyone’s order shipped yet?

    • Nicole

      No, they sent everyone an email that the warehouse is backed up due to the demand.

      • Nicole

        I just got mine!
