First mattress

[Hodan85]

Hi - we are looking to move DS into his first proper bed. We have the bed frame ready, but I'm looking for advice/recommendations on the best single mattress to go for. We are hoping to collect today, but have all the big stores local to us. TIA

Can I ask what you went for?! I need to get a single mattress for my 2 year old, and so many say suitable from 3, 4 or 5 years! Thank you very much.
