Messy Me Highchair Cushion for Hauck Alpha Plus wooden highchair - Easy to fit - Fully wipe clean highchair pad

I've had the Hauck Alpha high chair for awhile and have been looking for a good cover to fit it. The ones made by the manufacturer ship from Germany and are about $20 more expensive than this one. This one is is indeed easy to put on. It also cleans up very easily. The top part stays very secure.However, when I was installing the bottom part, I noticed that it hangs over the chair piece a little bit more and also the velcro straps underneath are barely long enough to reach. The bottom part also tends to slide around because of the material. My mom has difficulties lifting my son and so at two years old, he climbs up the chair himself and needs her assistance turning around to sit. The bottom part can make this difficult. I wish the velcro straps were longer so that the bottom could be secured more tightly. Maybe a grippy fabric on the back of that bottom piece would make this a five star product.
