To be fair my house temp ranges from 15-20 oC. Its well insulated triple glazed and no matter what temp is outside it retains heat very well.
On the other hand it gets very warm on that hot day we get every couple of years up here.
For me the temperature change isn't an issue but i can see how it could be. I've not always lived in warm, well insulated houses
I don't have cases for every bass either so this was cheaper than buying cases and i'd have nowhere to store 5-10 basses in cases. All i have is my tiny bass cave to escape the pleasures of life.(hoover, washing machine and 4 bloomin cats)
My main working bass the Sandberg VM4 is kept on a floor stand cause i find it easier to use from that on a daily basis. The others are either back ups or for specific bands or projects i've been in over the years. 3 of the basses in the pic have now gone.
