Hi, baby is due in May and i've got my heart set on a co-sleeping bay cot. I've been tracking them on Ebay but they are almost always collection only which is difficult for me as I do not have a car. What's the most reasonable price you've found them online? I'm on a pretty tight budget.
If the mattress heights match up well - you can get away with using one of the basic small Ikea or Kiddicare ones and attaching that to the bed. I did with both my kids as the mattress heights happened to be exactly the right height (luck not planning). They're like £30 or something as well so it might be worth looking into. I know the Kiddicare one is the space saver cot - Ikea is something like Gulliver but don't quote me on that (it's the one that comes in like green blue pink white)
Have you considered rental? I think with the ikea one you have to buy the mattress separately, so it doesn't work out that much less really... It's not intended to be attached to the bed either, so could be a safety issue. Rental of the bednest worked out to about £140 ish for 6-7 months, including everything - sheets, pick up and delivery. Plus I won't have yet another item of furniture cluttering up the house when it's no longer in use.
As far as I can tell it only appears to be a very bargainous 14 Euros however I might well be totally mistaken. Can buy same product from a site called stubenwagen.de and they definitely say 14 Euros delivery within EU
