small cots

Hi Our twins are now outgrowing their moses baskets and need to go into cots but we are limited in terms of space. I have been given one cot so would like to use that as a starting point so I don't have to buy two. The cot we now have is 126cm long including the frame. We can fit either a second cot max 121.5 cm long including the frame or a space saver cot which is about 96 cm long. 

I have two questions

1) Does anyone have a 121cm cot - what's it called please? I'm struggling to find one online. 

2) Do you have a space saver cot. What age can your baby use it to. Is it squashy for a toddler (don't want to have to buy another cot in a year!). 

Many thanks
