Mattress help pleeeease!

[Lozzabell]

Currently pulling my hair out over picking a mattress for my DS new cot bed.
He's moving from the co-sleeper as soon as we have the mattress.

Any recommendations would be greatly appreciated.

Currently considering the best one Mother Care do which is £150. This seemed a lot until I saw Mamas and Papas sell one at £250...! Now, I'm a sucker for the phrase 'you get what you pay for'... but we just can't stretch to £250.
My other half wants to buy a mattress from Amazon which seems to have all the selling points of the Mother Care mattress but at a third of the cost.

Helppppppp

Have you tried babymattresesonline? They make to measure.

I also bought the £150 MC mattress 3 yrs ago is that the zip off cover one? It's a lovely mattress & so ideal to zip off the cover esp if yr little one has had an accident/been sick etc. Problem with Amazon u can't view it before hand/knowledge from the shops etc.

I'm also debating whether to use my mattress again for 2nd baby (due in feb) has been covered over & only stored in a bedroom as my 3 yr old is now in a full sized single bed but am concerned/worry you about using a mattress 2nd time round instead of buying a new one, any thoughts?
