Just set up myself without major problems - took about 20-30 minutes. Does require 2 people to hook up to the bed. I am 5'9" so I am able to reach the slots to slide the rail underneath the bed, but a shorter person might have difficulty, but don't plan on using that feature for now.

I ordered this for my son's bed. The two "bars" that go under the mattress are like 2" thick! They lift the mattress up to where it doesn't even lay flat! Look for something with thinner, more practical parts! This is going back today and I'm buying one that costs more but actually lets the mattress lay flat like it should.

bought this specifically because it was extra long. not seeing any "double" extra long available, i just bought two of these. these are NOT designed for 2 to be used on each side of bed; it's just poorly designed. if you only need one, it MIGHT be ok. However, i find that the things that stick out on the side for the railing to "lock" into is just a scrapped/bruised knee waiting to happen either for my daughter or myself. will be returning.

We bought this product for use on a bed that is occasionally used by adults, and I was hesitant to believe that the rail wouldn't be felt when it was between the mattresses. I have to say, I have been impressed -- it was easy to put together, sturdy and would fit any size mattress. It slides easily under the bed and the bed is just as comfortable when the rail is down!

This was a wonderful aide in the transition of our daughter from the crib to a big girl bed. The installation was a bit difficult as some of the pieces were mislabeled but I figured it out and was very pleased with the end product. The rail fits very secure to the bed and covers nearly the whole side of a twin size bed. I would definitely recommend this product.

I would recommend this product, however, I had to return mine to the store because the groove in which the rail slides on was very jagged. I think it became jagged as I was trying to set it up. As long as you read the directions carefully, it's not that difficult to set up. I did it by myself!

We bought this because the product description stated that it would work with even the thickest of mattresses. (Our 2-year-old sleeps on a very thick pillowtop.) While it is higher than most, it only goes a few inches above her mattress, which was a bit disappointing. At first we were going to return it, but it is the ONLY product we found that will even go this high and a few inches is better than nothing. So far, it has held her in on numerous occasions (prior to using it, she'd fallen out of bed a few times). Set up was fairly easy. Transporting it not so much, but it is doable. It's nice and long too, so if your child moves around a lot, it's a good choice. Just note that it only fits on one side of the bed -- works good if the bed is up against the wall on the other side.

I bought this item for my 4 year old daughter. She and I share a room and she moves around a lot while she sleeps. She was falling off the bed often. We have carpet so she wouldn't get hurt but it would wake her up and disrupt her sleep. I took a chance on this product even though it says on the description that it only fits up to a Queen sized bed. I have a California King and it fits just fine. So for anyone out there that is letting the size limit stop you from buying this product, don't! The straps are plenty long for my Cal King mattress and the bed rail is completely secure. This is a great product and i would recommend this to a friend.

If you co-sleep with baby, or are considering co-sleeping, this is great added safety for the parental bed. Then, when child moves into own bed, it'd be perfect added safety for child's bed. I purchased 2 of the rails online for my child after the birth of grandbaby with free shipping to a Walmart store near my child's home.

We bought this for our 2 year old and so far so good. I only wish the sides were a little bit higher. The products need to catch up with products they are combatble with and it is rare to find a mattress that is not deep these days but these were the deepest sides out there.
