Thrive Kids Trundle Support Foam Mattress – 10cm Medium Bunk & Trundle Mattress

Need a slim mattress that fits a trundle or bunk safely? The Thrive Kids Trundle Support Foam Mattress is a compact 10cm reflex foam mattress — 30 density for a medium, supportive feel — that distributes a child's weight evenly for comfortable, supportive sleep. Its low-profile design fits raised and pull-out bed frames where a deeper mattress won't, and the silent all-foam build is ideal for shared rooms. Hand-made in the UK and delivered rolled.
