With six different strolling options for parents on the go, the Safety 1st onBoard™ Slide 6-in-1 Travel System with SafetySlide™ Base is the perfect lightweight car seat and stroller combo for your family. This travel system includes the onBoard™ Slide Infant Car Seat featuring SafetySlide™ Base. The innovative design of the car seat’s base makes it easier to get baby in and out of the car— even from the middle seat. Simply slide your baby toward you, lift, and go. No more back strain and head bumps. The SecureTech™ red-to-green indicators on the seat’s base allow you to see when your base is locked in place when using the SafetySlide™ feature. Plus, enjoy quick, easy installation every time without having to tighten the connectors manually—by easily attaching the base to the vehicle seat in just seconds with the rigid LATCH connectors.

The modular stroller features 6 ways to stroll and can be used as an infant car seat carrier, lie-flat baby carriage, and toddler stroller—all 3 modes are reversible and can be parent-facing or forward-facing. This compact stroller fits children up to 50 lbs. and 45" and is super lightweight with an aluminum frame. The all-wheel suspension, adjustable footrest, and quilted seat provide a more comfortable ride for baby, while parents enjoy a one-hand telescoping handle with faux-leather trim and a removable bumper bar for easy in and out. The oversized canopy provides extra coverage and the mesh peek-a-boo window lets you get a quick look at your child. The easy-to-fold stroller folds flat with removable back wheels for compact storage and includes lockable front swivel wheels and linked brakes.

Connecting the car seat to the stroller frame is easy, too. The ultra-lightweight car seat design at just under 8 lbs. makes it simple to carry. The 4 harness heights are designed to give your child a better fit from 4–30 lbs. and less than 32". The harness adjusts easily from the front of the seat with a simple pull to securely fit your child. The buckle adjusts in two ways so that you can customize the length and the buckle’s position on your child. Since every car is different, you can also adjust the base height for the right fit to your car. 

When using the vehicle belt, car seat installation is simplified with SecureTech™—Safety 1st’s innovative technology that solves the most common installation problem 7 out of 10 parents unknowingly have: loose vehicle belt tension. The red-to-green visual indicators show when the seat belt has tension.

Your baby will be nice and comfortable relaxing in the soft fabrics and plush padding. Smaller babies get the extra support they need with head and body inserts that can be removed as they grow.

Noticeable Support for Calm and Clarity
Size: 90 Count (Pack of 1), Size: 90 Count (Pack of 1)
This magnesium L‑threonate supplement has been a great addition to my daily routine. The capsules are easy to take, gentle on my stomach, and I’ve noticed a clearer, more focused feeling throughout the day. It also brings a nice sense of calm in the evenings without making me groggy. The formula feels clean and well made, and it fits effortlessly into a wellness routine. If you’re looking for a reliable magnesium option that supports relaxation and mental clarity, this one is a solid choice.

Highly recommend for sleep, mood, mental health
Size: 90 Count (Pack of 1)
I recently re-discovered this supplement, and I'm buying extras left and right and recommending to everyone I talk to. I've been working on increasing my HRV and supporting my nervous system, and the L-threonate is a rockstar for that. I was taking glycinate for a few months, and I found an old bottle of this one and added just 2 capsules, and the effect on my sleep was immediate. Way better than melatonin. My Fitbit is tracking much lower restlessness and more deep sleep, and I actually wake up feeling refreshed ?? and before my alarm, even! I'm noticing lower anxiety and an overall better mood, and it's only been 4 days. This bottle definitely holds its value, and the price is good, especially if I can get these benefits with just the 2 caps and not 3.

Big winner for helping BETTER SLEEP
Size: 90 Count (Pack of 1)
Life Extension is top of the line on most things they have. also pricier than most, but I buy three items for them regularly for many years. This Neuro-Mag with L-Threonate is excellent for boosting better sleep. This is a newer addition to their line. I also suggest trying their Mult-B complex and their B-12 elite (sublingual) On nearly all items, their quality control is near THE TOP of all suppliers. They also have supported vitamin and supplement research on my items over the last 40 years

Energy and Clear Thinking
Size: 90 Count (Pack of 1)
Great product. I use various forms of magnesium for different things . This form was suggested for clearer thinking and energy, and it delivers! I use it in the AM and it helps keep me energized I do think it varies by person how it affects you though as some folks get drowsy w/ it. Just a heads up to test on a weekend perhaps. I won't be without it now!

Capsules Are Too Large and Have a Strong Plastic Smell
Size: 90 Count (Pack of 1)
I’ve purchased this product twice, but the capsule design is a big downside for me. The capsules are very large and difficult to swallow. On top of that, there is a noticeable plastic-like smell from the capsules, which is quite distracting and unpleasant. It makes taking them every day uncomfortable. The product itself may work as intended, but the capsule size and odor seriously affect the overall experience. I wish they would improve the capsule material or offer a smaller or odor-free option. If you are sensitive to smells or have trouble swallowing large capsules, keep this in mind before buying.
