Moses basket & DM. Your advice please (a little long)

[TakingTheStairs]

My family have a really lovely wicker moses basket and stand that was used for my Dad and also for me and my siblings too. My mum has kept it for the past 30 odd years in the loft and she took it down so that I could use it for my child. I'm due early Dec.
DM & DF have made a huge effort, hand washed it, bought a steam cleaner specifically to make sure it was as clean as possible. My Dsis is sewing a new lining and bedding for it (as the stuff that was used for my siblings and I is awful polyester that would not pass any fire safety tests now!).
I really was so proud to use it for the third generation.. but there's a problem. The base of the moses basket has buckled and made quite a substantial hill/lump that pushes up inside the base of the basket.
DM & DF have taken it to a specialist weaver to see if it could be fixed or the base replaced or anything like that but unfortunately it can't be made better.
My DF is a little upset. It was his moses basket as a baby and I think he's finding it hard to get his head around that it might not be able to be used for a third generation.
My DM is saying that it will be fine, that I should put a blanket around the lump to make a level base and then just put the mattress on top of that. Today my DM said she did that with my little sister BUT when the issue came up originally a few weeks ago she said it wasn't like that at all for any of my siblings and it must have happened while it was being stored in the attic in the past 30 years.
The thing is, my DM has a tendency to try and solve issues with solutions that aren't logical just so she can say that she solved the problem (if you know what I mean) so my judgement on whether to trust her on the blanket issue is skewed.

I don't want to upset them (esp my DF as it was his originally) but having said that, my DF will be quite practical and reasonable once he has had a chance to get his head around the disappointment if the basket isn't really viable.

So..would you be happy to use a blanket or something like that to even up the base and then put a mattress on top of it, or would that be silly or dangerous in some way? I don't want to upset my parents BUT my future child's health will take precedence.

help!

could you put a false base in? at a slightly higher level? I know its not the same, but something just to level it out, or even two matressess (i do not know how this would work just brain dumping here!!!)
Another option would be to get another nbsket and just whip out the old basket so your DF isn't too upset when he visits?

We don't have room to have two moses baskets (and certainly not the room to be able to hide one from my DM!) but I like your thinking on the other things.
I wonder could we get two mattresses and cut a hole in the bottom one to accommodate the lump and then have the other one on top so it would be even?
Would that make the baby too high in the basket?? hhmmm

A false base made from a bit of hardboard/mdf would sort it, a local traders yard might even cut it to size for you, then pop the mattress and bedding over it and it'll be good as new.

I would get a false base now for it, and then put it in the moses basket and then place weights on the top to try and even it out, but would comtinue to use the false base when using it for the baby as it will make it more stable.

I think a false base is the way to go for sure thank you. We have tried weights and cast iron dishes filled with weights on the lump but no luck.
