The dining area in our house is relatively small; we have a dining room table and four chairs and there really isn't much room for anything else. So when we found out we were expecting we didn't really want to try to squeeze a high chair into the area as well. I registered for this space saver high chair and it worked great as a high chair. The information on the box said it could also be used as a booster seat, which is another reason I choose this item on my registry. Unfortunately, the booster seat function did not work for us at all because the arm rests on the chair were too high to fit under the table top, so we could not slide the chair close to the table. Sturdiness We found this to be very sturdy and durable through two kids, despite them being rough on it as they got older. Durability See comment under Sturdy! Design I'm giving this an 8 because of it did not live up to it's claims of versatility as far as booster seat goes. It was wonderful as a high chair. Safety Love the five point harness for younger kids! Ease of Cleaning The tray is easily removed with one hand and it is dishwasher safe. The seat cover does wipe up nicely but it is also removable and can be put in the dishwasher, along with the straps. Giving this a 9 only because the seat cover is a pain to remove and put back on.
