These bed rails work great, I had to buy all four in order for it to be sturdy. That being said… USE ONLY UNDER SUPERVISION!! I put all four rails up and put my seven month old on the bed and went to make her a bottle heard muffled screaming and came back to her face down wedged between the mattress and the rail, with her face in the side of the mattress, she was unable to turn her her or move! I am sick thinking of what could’ve been. I just want to warn other parents not to think of this as a “safe space” like you would a pack n play or a crib!For those complaining about the logo.. you can see from the Amazon pics it’s there so don’t buy if u don’t like what u see.. lol hilarious to me!! I use to block open side of my daughters bunk bed and it works perfect ? I never bring it down cuz I don’t want her to see it as an option/something to try to mess with since she’s 3 but to each their own for sure. Overall great product and would buy again for sureThis are great quality. Easy to assemble. My only suggestion is to include include a couple of wall anchors. Only needed the one long and one small side since the bed is up against the wall so a couple wall anchors were needed. Also, the height adjustment to place the supports needs to be long enough to cover the mattress frame and the mattress. Placing the L shape supports in between the mattress frame and the mattress is not very stable, baby will push up against it and it comes out dropping to the ground. Once the wall anchors were added this was not an issue. Could definitely can use some design adjustments but it is okay as they are. Definitely solve our issue of baby growing and us not wanting to use a crib.It’s good for smaller babies but not strong babies.We bought these for our bed so our dogs aren’t on it all day while we’re at work. We live in a studio apartment so they always have access. I loved the idea of this because it was easy to slide up and down but when down the poles in the corners stay up and the one was blocking my view to my tv so these didn’t work out for me. I got other ones that folded down and even when up they aren’t tall enough to block my view so the one at the foot of the bed stays up all the time. The ones listed here are nice just not what I personally needed. I also didn’t like the big logo pasted in the middleThe height is adjustable but the length is not. On side of my king fits ok but not at the bottom. Not that easy to put together.The mesh part of this bed guard is white, with a GIANT, extremely ugly black logo printed on it. It's an elk (?) wearing sunglasses with "BOSHI TANGHUA" written around the elk. It covers the entire bed guard. SO tacky and ugly. If you have a bedroom decorated with camo and hunting/ outdoor theme it could work (?) but otherwise it's a hard no for me. I saw that and immediately knew it was getting returned.PROs:SturdyEasy to assmbleThe buttons work well so you can take one side or both sides down. (Note that when you do this, a big pole remains sticking up on the bed).CONs:That awful logo.When you move the sides up or down, the button makes an extremely loud metal-on-metal "click" noise that would absolutely wake our sleeping toddler.The button only works from the outside so if you are co-sleeping I imagine it would be very difficult to do by yourself from inside the bed.The button felt flimsy.When in the "down" position, the fabric bunches up, and while I didn't try, it seems like it would be tricky to make the bed behind the bunched fabric.2 more "FYIs" if you're still considering this guard:1) The image shows that the top and bottom rails come apart in 3 pieces. This is not accurate, it's only 2 pieces. We needed a shorter rail and only planned to use 2 of the 3 pieces and let the fabric bunch up (or I was considering sewing it). Obviously this was not possible, since there are 2 pieces (not 3) and each piece is exactly half the length of the bed rail. I think I saw in the questions that someone wanted to travel with this (bad idea if you're flying, it weighs a billions pounds), and the 2 pieces might fit in a giant suitcase but definitely not a carry-on. Just fyi.2) I bought the Amazon Warehouse deal version of this product for $63. Generally, warehouse deals are in perfect condition but this one arrived in the manufacturer packaging (no outer box) and it was completely torn up, definitely not meant for shipping. The hardware to connect the "feet", as well as the strap, were both missing (probably fell out the gaping hole in the box). There were only assembly instructions in German. For this item, I'd probably skip the warehouse deals unless you're handy and/or don't mind buying bolts at the local hardware store.Good luck!These screens are great for the bed. It’s breathable and it’s sturdy..you have to have the right type of bed frame for it, but it gives me a peace of mind knowing that my baby is safe. It’s also easy to slide the screen up and down for ease of access. I love it.
