The One4Life® Slim all-in-one car seat takes your child from birth to big kid with trusted Britax safety, ClickTight® installation, and a slim SpaceSaver™ design. As a convertible and harness-2-booster seat in one, it grows with your child for 10 years. It starts rear-facing with an extended capacity of up to 50 lbs., so your child can ride rear-facing longer. It easily converts to forward-facing toddler mode (up to 65 lbs.) and high-back belt-positioning booster mode (up to 120 lbs.) when your child is ready. With a slim outside and spacious inside, the 17.5” seat is designed to fit 3 across* without compromising safety and comfort. ClickTight helps you install with confidence, every time. The base and shell are easy to wipe down for hassle-free cleanup. The car seat cover is safe to machine wash and dry, and it’s naturally flame-retardant with no added FR chemicals. One4Life Slim features a high-strength steel frame, a SafeCell® crumple zone, and a V-shaped tether. As your child grows, you can easily adjust the 15-position no-rethread harness and headrest with one hand. With cooling channels, premium padding, three infant inserts, and built-in armrests, your child will love every ride.

Perfect!
Scent: White Peach, Size: 14oz
Everything you would want in a pet hygiene product. Pet hair type I used this on: low shed, dense cork screw (tight curl) hair/fur. Excellent lather, even application, clean and easy rinsing. The scent is lovely and gentle, perfect for my human senses and -more importantly- the animal minded fragrance notes are happily accepted by my pet’s delicate olfactory system. I start spa bath time by offering an open cap sniff of the products. This is one we both prefer. My pet hasn’t run from the room or attempted to flee the wash basin 🙂

A Gentle Clean That Leaves My Pups Smelling Incredible
Scent: White Peach, Size: 14oz
Mrs. Meyer's Clean Day 3-in-1 Dog Shampoo in White Peach is a breath of fresh air compared to the harsh, chemical-heavy formulas often found on pet store shelves. The 3-in-1 claim—cleansing, softening, and freshening—actually holds up; the formula lathers well enough to cut through dirt and grime but rinses out quickly without leaving any sticky residue. Because it is made with essential oils and plant-derived ingredients, it feels very gentle on the skin, which is a huge plus if your pets are prone to itching or dryness after bath time. The standout feature, however, is the scent. The White Peach aroma is light, fruity, and natural, avoiding that overpowering "wet dog covered in cheap perfume" smell that other brands tend to produce. It strikes a perfect balance: strong enough to neutralize odors but subtle enough that it doesn't seem to bother the dogs' sensitive noses. It makes the entire bathroom smell like a summer orchard rather than a grooming station. Most importantly, the lasting freshness is unbeatable. After using this, my dogs smell absolutely amazing—clean, sweet, and huggable—for days, not just hours. It completely eliminates that lingering "doggy odor" and leaves their coats feeling soft and fluffy. If you are looking for a shampoo that makes you actually want to bury your face in your dog's fur, this is the one to buy.

Works as advertised
Scent: White Peach, Size: 8oz
Exactly as described. My dog seems to enjoy the spraying and wiping process - no struggles. I am not fond of the aroma, even though I usually love anything peach. The smell lasts several days on the dog, so we're not smelling the "dog" smell as much.

Mrs Meyer's works well for stinky pets.
Scent: White Peach, Size: 14oz
This is the best shampoo I've tried to get rid of stinky dog odor and I've tried many! Another shampoos when you wash the dog the smell would return the next day. But with this one the smell lasts for days, ridding her body odor & leaving her coat soft fluffy and the peach smell is pleasant enough to cuddle.
