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.

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.

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 Playmat to Promote Development and Increase Tummy Time!
Okay I absolutely LOVE this playmat!!!! And I am pretty picky and literally have spent months looking for the perfect mat for my baby boy! I finally took a chance on this one and boy am I glad I did!! It is a gorgeous mat with so many features to promote development! And it makes tummy time so much longer and much more fun for my son! He’s even started to roll over and the mat is so soft and a bit padded which is ideal for this! He never seems to get bored of playing on it and just seems so comfortable and engaged when he’s on it-whether he’s on his back or tummy! I contemplated other mats like I mentioned before but I am so happy I chose this one as it doesn’t have all those “lights and noise and whatnot “ but more so it has things that promote his imagination and brain! I would highly recommend this mat to any mother!

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.

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.

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 theclips 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.

Kinda meh
I really wanted to like this play gym but ended up returning it.Pros: has good hanging contract “toys” that are easy to move from place to place; great colors and textures; easy to set upCons: the hanging bars hang too low and this gym doesn’t “grow” with the baby well; it’s not easy to fold up if needed; the mat is on the thinner side.
