Baby loves it

I just bought this as a second play mat for friends baby, because I have one myself for my own baby and it was a total game changer for me. My baby who hated tummy time, actually started enjoying it. Its so cute. He tried to grab at the floating fish and catch them. It keeps him occupied for a very long time. This is definitely a great investment!!

Cool but room for improvement!

I was so excited to try The Opus’s Ocean of Discovery tummy time Mat because of how fun it looks; it is a very easy setup. It comes with multiple instructions, which is excellent, and the mat is made of thick plastic even my four, and 6-year-old that love sensory toys enjoys it The beautiful colors and floats objects I found it great for kids with Hyperactivity as well. I do feel there is room for improvement my baby is three months can't barely fit; so making it bigger in length and width will make a difference but I do understand that make it bigger would also be tougher to move and set up so maybe having the top floor filled with water and the other half of the floor filled up with air instead of water I found it can be an option. So half and half the ring sides ... MoreI was so excited to try The Opus’s Ocean of Discovery tummy time Mat because of how fun it looks; it is a very easy setup.

Opus’s Ocean of Discovery Tummy Time Water Mat Is really cute for a baby on tummy time or crawling. The Mat comes in folded well and then you have to fill the outer edge with air and the interior with water. The material is similar to that of a floaty. Once you fill it up you lay it on the floor. Beware of older kids over the weight restrictions wanting to play and jump on it. It’s makes me nervous of my older daughter who is at the weight limit. I admit i am not confident I feel safe leaving it in the floor as I worry it may pop or snag on something. My son is a younger toddler that has learned to walk but he still likes to plop on it and get the foam animals inside to move for a few minutes. I recommend supervision to make sure the babies head wont fall on the mat ... MoreOpus’s Ocean of Discovery Tummy Time Water Mat Is really cute for a baby on tummy time or crawling.

This does keep his attention for a few minutes at a time but he moves on to another toy. I’d recommend this more for babies who have not picked up on walking yet as this will be interesting for them and something new to look at. It’s easy to fill up and use.

Cute toy for a little bit
4 June 2021

My son is at the upper end of the age range for this toy. I believe it would probably be better suited for younger babies. While it's very cute and colorful and my guy was excited to play with it while it was in the box, once we inflated it and filled it with water, he was a little underwhelmed. He really wanted to be able to get the sea creatures out and play with it. While he did sort of smoosh it around and play for a minute, he quickly moved onto other toys. Assembly was easy. You blow up the outer part and fill the middle part with water to a fill line. A younger baby who still does tummy time would probably really like this cute toy.

Encourage exciting tummy time

I bought this product for my new grandson. Hes just learnt to roll and loves focusing on the floating shapes. Its colourful and soft to touch. Easily his favourite toy.

Such a cute mat and so engaging!
9 June 2021

My niece is having such a good time on it. Mat is of decent size, good quality and comfortable. I filled inside with water and outside with air without any leaking issues. I somehow finds it stress buster too for myself when I move my hands on it. Bright colored sea creatures adds to her curiosity. We love it.

Super Cute & Perfect for Tummy Time!
28 May 2021

I am so thrilled to share my thoughts on this tummy time water mat. This is perfect for babies from as young as 3 months old starting on tummy time to older babies that are sitting up. This mat is very cute and easy to setup. The center of it gets filled with water and the outer rim gets filled with air. My son loves sitting on this mat and reaching down to touch the floating animals and shapes. I'm happy that he is having fun while working on his gross motor skills. We toke it along to grandpa's house during the weekend and it was easy to fold up and wipe down for traveling. I would recommend this as a perfect baby toy that works on muscle development that is fun and engaging!

Very interesting toy
29 May 2021

My baby is so excited to play with this Opus’s Ocean of Discovery Tummy Time Water Mat from Baby Einstein. It was very easy to start using the mat. I inflated the mat by mouth quickly and filled with water. I like the quality, it is well-made. The mat has bright colors, wonderful patterns and 6 sea creatures inside.The material is very easy to clean.I would recommend this toy for others.

Very well made material!! Amazed me!
29 June 2022

My baby likes to play on this mat.One day my friend brought her 4 year old girl to our home and found she was jumping on this mat. I was so scared she would break my daughter's mat and afraid the water will splash, but somehow it was totally fine. I realized this material is very high quality.My husband and I were so amazed!Now we let our baby jump on it.

Was great until it got a hole
9 June 2021

The Opus's Ocean of Discovery Tummy Time Water Mat was very entertaining for my little one and at first felt as it would hold up. While it was a source of entertainment and fun for my little one, a pin size hole happened to appear while he was playing on it. There was nothing on the floor nor was there anything else that could have made that hole from what I could see so I'm not sure how it happened. I am concerned that after only a couple weeks it wore down enough to put a hole of any size in it.I was sent this item complimentary in exchange for my honest review. All comments and opinions are my own and in no way influenced by this.
