Beautiful
It’s beautiful. I went with this one instead of the more spendy lovevery one I had my eye on. It’s maybe a little smaller but it’s super cute, has many lovely toys and similar color scheme as lovevery and not overly stimulating like some other loud and obnoxious play gyms on the market! I got it half off with open box, I figured if it was messed up I could return it and buy new however it arrived with a little bang up box but was totally perfect and like new inside. It arrived with all the toys and even the sticker to protect the mirror is still on. Very very happy with this purchase and the money I saved. I will add a little pull toy from taf toys that has a color changing light and plays some soothing sounds, add some more toys and contrast flash cards… very happy with this purchase.

Great
Excellent functionality for early STEM skills, with vibrant colors that hold little ones’ attention. Great value for money — sturdy and durable, surviving lots of play without wear. Assembly is super easy, and the pieces have no scent, just a clean, safe feel perfect for babies.

Best activity gym for the money
Searched and searched for the perfect activity gym. We also have the firsher price piano activity gym, but liked this one better as it didn’t over stimulate. I loved that it comes with a little pillow to assist with propping baby up for tummy time. The mat is very easy to clean as I just toss it in the washer and hang dry. The attachments are held in place with sturdy Velcro which is nice that you can position toys where you want if you need to get baby to look a certain way because of torticollis or preventing flat spots. Great sensory item that helps baby focus. He loved the high contrast black/white/ red colors. I also loved that it iced you tips and hints on what you should be doing with baby according to their age. Looks simple, but much more educational than others on the market.

Perfect!
We've used this playmat with our baby girl every single day since we got it three months ago. My daughter LOVES it. When she was really tiny she would bat at the toys; the rainbow has the most beautiful chime in it, she adores the sound and works to make it chime again and again. The toys on it are all soft and easy to see, the pillow is just the right size for her little head. Now she flips over and can reach around to toys while on her tummy. It's lightweight and easy to move around, and you just unbuckle it and toss it in the washer to clean it. It's also just so pretty and soft while still having high contrast toys for baby. It was definitely a good buy and worth every penny.

Love the design
I really liked this mat for my baby. I love the black and white. It has different things/ideas that you can use it for. I don't really like the fact that any hair or dust gets stuck on it super easily. But overall it's great.

OBSESSED
SUCH A GREAT TUMMY TIME MAT!! I love everything about this mat. It’s has great ideas in the center of the mat to help with learning, most of the toys are Velcro, thus removable, and makes for easy play. I have two active dogs and it is easy to clean. Basically just dust it off with your hand and hair and dirt specks come off. It takes a minute to figure out the clips but I wouldn’t take any stars away from it because of that. I love how it goes from an overhead play gym to a play mat. It would make a great gift!! It also doesn’t hurt that it’s cute when you take pictures of your baby playing.

Great play mat
My little one loves this mat! I was originally going to get the expensive Lovery one, but so glad I opted for this one instead. Keeps her entertained for a good amount of time and I really feel like its helped her reach for things. I like that the toys can be moved around or adjusted and that there are different textures and sounds. Plus, the black and white colors grab her attention and it’s not a complete eyesore to my living room. It’s a great buy!

The only baby gum and toy you need! So good I had to write a review!
I love how this is designed! This is our second babe and I felt a little silly buying a new play gym but our old one was too busy and not very engaging. My two month old LOVES - literally loves - this play mat! There is a gentle jingle toy, a mirror, and high contrast toys without being overly stimulating. My favorite part is the design. You can Velcro the various toys wherever you want and adjust them super easily. There are a few that stay on the arch but can be removed if you unclip the arch and slide them off. I also love that you can lower the arch so nothing is above their heads if it’s getting too busy. It’s super cute and really developmentally appropriate. There’s tactile toys and visually appealing toys. I love the rainbow pillow for tummy time. I never write reviews but I always read them when making a purchase, especially for baby things. This was good enough for me to write the review lol. Everything the company thought of for this play mat is intentional and designed with parents and babies in mind!
