I find this excellent for winter sinus trouble because it keeps the dry air from irritating the nose. It is good for colds also.

Love, love, love this chair! My child (12mo)sits closer to the table at restaurants and at the correct height (some restaurant highchairs sat lower than the table, making eating awkward). Have not experienced a problem with it not fitting around table edges as other reviewers have mentioned. In restaurant highchairs my daughter slid around, often ending up needing to be re-adjusted, this is no longer an issue. Just cleaned it for the first time- easy to take apart, cleaned up well in washer. Has great seat padding which looks much more comfortable than other portable highchair options. Folds up nicely into its attached bag for transport. The only negatives, haven't used this when dining alone with my daughter, I don't think I could manage her AND affix this to the table- it's a two-handed job. Also, when attached to a dining table, there is about a 1 inch gap between table and child- food falls through this space when she (Frequently) misses her mouth. All-in-all we LOVE this product!!!!
