### ⭐⭐⭐⭐⭐ 







  
  
    Great mattress at a great price
  

*by A***4 on Reviewed in the United Kingdom on 15 November 2024*

I got the Doubleslee Memory Foam Mattress for my 3 and 5-year-old, and it’s been a brilliant choice! The medium-firm feel is perfect—not too hard, but supportive enough for growing kids. They’ve both been sleeping soundly through the night, which is a relief!The soft, skin-friendly cover is gentle against their skin, and the mattress itself stays cool, even when they’re bundled up. It arrived quickly, was easy to set up, and expanded fully within a few hours. Highly recommended for little ones who need a comfortable, supportive sleep surface.
