Question: does mats come with velcro to attach several mats together?
Document: We use for practicing tumbling at home. Nice and thick. I like the Velcro strips that you can use to attach multiple mats together.
These are great mats for the boys to practice their gymnastics on. We have several of them set up in the garage on the cement floor and I was worried the 1.5&#34; mats would be too thin but for tumbling they are just fine. The velcro holds the mats together nicely, my only complaint would be that the gab between the mats is about .75&#34; not a big deal, I had just assumed they would fit flush.
It has strong side velcro to attach multiple mats together. You could also fold the four panels in half so it's only two panels thick by two panels wide, for if you are short on space or want more cushion.It did have a plastic smell when I first opened it but the smell went away after a few weeks.These mats are more comparable to what you would find in a martial arts school or a gymnastics school.
My kids are into dance and gymnastics and we wanted mats that allowed them to train at home. I looked at several outrageously priced mats and almost gave up until I found these. The covering is excellent quality and the padding is the perfect stiffness. An added bonus, they come in pink! The shipping was really fast. We couldn't be happier with this purchase.
It has the velcro to attach another/series of mats for professional applications. This is not a cheap mat!
We bought this for our daughter's 7th birthday and she loves it. The mat is excellent and had velcro to attach additional mats end to end. This mat does not have velco on the sides, but I knew that going in. Great price and a great product.
Nicely made with thick pad foam and 4 sections that all have velcro stitching to attach other mats if desired. Kids love tumbling on this mat and my wife and I use it now for our yoga and stretching also. Seems sturdy and good enough to simulate the actual tumbling mats at the gym.
This definitely exceeded my expectations. My daughter has been asking for a tumbling mat for several months. She springs into cartwheels and handsprings all over the house. We definitely needed the longer one so she could use the full length for tumbling. There is velcro on the edges to add additional mats which is a plus and the depth of the mat makes for safe landings.
I ordered these mats for my daughter to practice gymnastics on. Although they don't have a lot of cushion to them, they are very good for multiple configurations and fit together well. The Velcro on then is strong. They also arrived very quickly and packaged  well.
I bought these mats to practice Brazilian Jiu-Jitsu at home. They are the perfect size and thickness (I bought the 2 inch). I got three of them, and they velcro together on either side creating about a 100 square foot surface. The surface is smooth enough to not cause mat burns. They fold up easily for storage or transport.
