Size is different from what is advertised. Actual item was only 11 cm

I ordered 2/ 22 cm medium -firm foam matress. After 2 weeks, not 3 days..I received a mattress joke: a smelly sponge, which, left for 48 hours (not 24), barely reached 12 cm. I tried to call a number I found online for the company with the mattresses, but it seems that no one works there..but, surprise...yesterday I received 2 more mattresses identical to the first ones..placed one on top of the other, they really have 22 cm. I understand that it is delivered in pieces??? The reviews I read, which it was good to have read before, show that no one solved anything by returning them at their own expense. So??

Really poor quality. Left to air for 72hrs and it only rose to 11cm not 22cm. Waste of time and money.

Very flat can be used for guests

The foam was completely shrinked in 5 months. Only way forward was to dispose. Don’t buy
