Tips for the Perfect Fit
-
Measure your space carefully: Bed frames are usually 10–20cm larger than the mattress itself.
-
Match sizes: Always pair a UK-size mattress with a UK-size bed frame.
-
Consider mattress depth: Lola Sleep mattresses are typically 25–30cm deep, giving a premium, supportive feel without overpowering your bed frame.
