# Materials used in kids' bike seats and trailers What materials are children's bike seats and bike trailers made from? THULE Yepp Maxi EasyFit: Hands\-on testing describes the seat as Crocs\-like weather\-resistant foam: firm and smooth, supportive, softer than hard plastic, very rainproof and easy to clean\. Thule Yepp 2 Maxi: Thule describes the seat as padded, foam and shock\-resistant, so the supported feel is soft and cushioned; no thickness is stated\. THULE Yepp Nexxt Maxi: The seat combines a hard outer shell with soft padding, and the seat is soft and shock absorbing\. THULE Yepp Maxi: After several months of regular use, construction appeared robust enough to last until outgrown\. The review identified steel structural hardware and a supportive, shock\-absorbing EVA polymer seat\. Thule Chariot Lite 2 \(model 10203022\): A Chariot Lite 2 owner found a tear and edge separation in the plastic window after only a few days\. Replacing the entire one\-piece fabric assembly was described as costly and difficult, so repair tape was considered\. THULE 20100506: The hitch arm is lightweight aluminium\. THULE 20201401: The kit uses aluminium, steel, plastic, wood and glass fibre\. ### 1.

(manual) Every value in the table is a fact RoboTrunk checked, linked to the page it came from\. A dash means no checked fact fills that cell\. Prices and stock change, so this page prints neither: each product name links to its RoboTrunk page, which shows them live\. Written 2026-10-19T11:34:34.755Z. This page is published by RoboTrunk, a store built for shopping agents. The store named on this page sells the product and ships it. RoboTrunk is not the seller and never holds the money. Buying works in one path. RoboTrunk's tools prepare a checkout at that store, then hand back a short-lived link. The person approves the total; once RoboTrunk has checked the store's total against it, the person is given the checkout link to tap in their own browser, or, if the person prefers and gives permission, their agent may open the link and finish there, and payment always happens on the store's own checkout page. RoboTrunk never takes the payment or sees a card. Where the rest of this site is: - /agent/story.md is what RoboTrunk is and how it works, in full. - /agent/tools.json is every tool, its arguments and its answers. - /agent/merchants is every store you can buy from through RoboTrunk. - /products/ucp is every store's indexed products. - /products/search is one search across every store, in plain words. - [What RoboTrunk is](/agent/story.md) - [Every tool, in your browser through WebMCP](/agent) - [The tools and how to call them](/agent/tools.json) - [The stores you can buy from](/agent/merchants) - [Every store's products](/products/ucp) - [Search every store at once](/products/search)
