The one that came with the bike is plastic and really uncomfortable. How is this one?** A: @Christina: Yes - this seat is padded. My daughter loves it. She has been riding her Strider since she was 2 yrs old and is still riding it over 2 yrs later (along with her "pedal bike"). The extended seat really gave it a lot of extra use. **Q: diameter of seat post** A: I believe it's 22.2 mm in diameter. Strider company can confirm this. **Q: We need to replace the seat that came with the bike, but my kid still uses it at 12". Can you use this one that low?** A: Yes. I just tested it. Dropped the seat within three inches of the clamp and the post does not project far enough under the bike to hit the ground. Hope this helped. By the way, my daughter rode her Strider bike for two years. When it came time to move to a "big person bike" she rode it without any trouble. **Q: How easy are the seats to interchange? we want to buy this for our almost 2 year old, but i know my very tall 3.5 year old will also want to ride it.** A: This taller seat can be used for both kids. My kids both used this (ages 2 and average height & 5 and tall at the time) and we just adjusted the height. ## Frequently Bought Together - Strider Performance Seat with XL Post - Fits All 12 and 14x Balance Bikes - Extends Seat Height to 15-19 Inches - No-Tool Assembly - Kids Bike Grips - 105mm Bicycle Handlebar Grips With Mushroom Pattern for Bikes, Balance Bikes, and Kick Scooters --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/434300974-strider-kids-extra-long-seatpost-with-saddle-black-30-5cm](https://www.desertcart.us/products/434300974-strider-kids-extra-long-seatpost-with-saddle-black-30-5cm) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-08-18*
