Just that really. I bought a memory foam mattress last year and the warm weather plus peri-menopause means that I feel as though I'm sleeping in a furnace on a bed of hot lava. I have a fan next to the bed but it's not ideal.
I'm on the verge of splurging £150 that I can't really afford on a wool and cotton mattress topper from Woolroom which promises a cooler night's sleep but if it works, it would be totally worth it.
Any suggestions?
