I was torn between this bed bumper and a more traditional bed rail. I loved the idea but I was nervous at how it would work. My 2 year old was going from a crib to a twin bed and I want her safe. I decided to take the gamble with this less traditional approach and I'm very glad I did! I put it directly on the mattress underneath the sheet and the mattress protector and it stays very well in place. It goes about 3/4 of the length down the twin mattress which is perfect. A side note about it: when it came it recommended using seppnfitted sheets, which I was not prepared for. However, my sheets happened to work well even though they weren't deep fitted. I was still nervous after setting it up that it may not be tall enough to keep her in safely (and she is a crazy sleeper in my experience), but it has worked so well! We have not had any issues at all. And as a bonus, the customer service of this company has been great. They have been very proactive in contacting me to ensure my satisfaction and to make sure everything is going well.

I had read some reviews about the bummper being a problem because it "slipped" and shiffted a lot. But there really is no other better alternative than that mesh fence. I would never be able to tuck my toddler in with that thing!!I decided to try the bummper out anyways.

This worked awesomely for my 2 1/2 year old. It actually does not move around. It DOES have a sort of rubber grip material similar to the ones you buy to put under rugs. Of course it is not cemented on there, and any movement I feel is inevitable with a worm like sleeping toddler who starts off head on pillow and ends up feet over bed. But I was surprised how I myself would tug on it from the side when trying to get toddler to sleep, and it really didn't budge so easily. It has shiffted an inch or two, because my toddler climbs over it like mount everest because he likes to make everything exciting. But by no means did it slip off. And I can't say it moved at all while my toddler slept on it ( he uses it as a pillow throughout the night too). I like it, it should work for you too.

P.S I didn't get this free or anything. I paid full price on Amazon. I just appreciate the company
sending out an email to check up on the product arriving and your satisfaction.

I bought this Hiccapop bumper and the Izo Chid Bed Safety Rail Bumper (also on Amazon). My 3 year old grandson just moved into a queen bed in the middle of the room. He's an active "helicopter" sleeper and managed to fall out of bed straight away. I put the Hiccapop bumper on one side and the Izo on the other side of the bed. The Izo is significantly bigger than the Hiccapop. The Izo is 6" h x 9"W x 56" long while the Hiccapop is 4.5"H x 7"W and 52" long.

My grandson bumped up against both bumpers as he slept. At one time, his legs went over the Hiccapop and another time his shoulder rested up against the Izo. He didn't go over either although It might be able to go over the Hiccapop. I probably should have tested both bumpers longer than two nights but I hope that the Hiccapop will be enough of a signal to him to stop moving in that direction.

I put both bumpers under the waterproof mattress cover and on top of the pillowtop. Neither bumper moved despite my grandson using them for leverage to pull himself up into bed and to dangle out of bed. My husband and I crushed the Hiccapop bumper (we didn't try to sit on the Izo side) to get into the bed to read bedtime stories.

The smaller Hiccapop looks nicer with the smaller bumps under the blanket and it's easier for us to get in and out of bed with our grandson. I have a 13-1/2" mattress with a pillow top and a waterproof mattress cover making the base about 14". With the Hiccapop, I can use my 18" deep sheets (but I really need 20" sheets). With the Izo, I need 22" deep sheets minimum. Consequently, I decided to return the Izo and order another Hiccapop. He has fallen off the bottom of the bed so I may order a third Hiccapop.

Get the Hiccapop if you want a lower profile look and don't want to buy deeper sheets. Buy the Izo if you have a really active sleeper who might go over a 4.5" barrier or if the bed is up against the wall and you don't want him flailing into the wall or if the extra length of the Izo is necessary so the baby doesn't fall off a "gap" into furniture such as a night table or rocking chair. The Izo really makes an effective barrier.
