I am looking for custom made mattresses.
Can anybody recommend a store with really good quality? Having read some of the threads here it seems to me, that local ones often have flaws (chalk...).
Any ideas are highly appreciated.

Get a memory foam mattress from slumbermaax, they are wonderful!

I tried a memory foam mattress but it was about as hard as a Chinese one. Sounds strange, I know.
Now I use a foam mattress topper.

I have had three made here. All serta brands. I would highly recommend them. Just added length to the king size bed. Not cheap went for the top end model this past spring and it ran 14000. Great bed though.

Sorry, for being off so long.

@LT - where did you have them made? The thing is, I need a special size to fit into another one I cannot change. Anyhow, no Ikea or normal size will do.

Sorry to resurrect an old thread, but would be interested to hear if you managed to find a custom made mattress. We are looking to buy one (with a Divan style bed) and, because of the size we're looking for, we will need to have it custom made. Any thoughts please? Thank you!
