The weather may be a little wet at the moment, but that hasn't stopped the humid air feeling stifling, especially when we're trying to get to sleep.
If you're still struggling to cool down at night, you may want to think about upgrading your duvet to a lower tog - and we've found a top-rated lightweight duvet that may not only be the solution, but is also on sale.
Why we rate it
John Lewis' Synthetic Soft Touch Washable Duvet, 4.5 Tog is the lightweight duvet alternative we need when it comes to the warmer months.
The microfibre cover is soft on skin, while the Sonicseam technology ensures the edges don't fray, for an-all round comfortable sleep.
The siliconised polyester microfibre blend filling works to trap heat to keep you warm, without weighing you down and causing you to overheat.
This design is machine-washable, as well as quick drying, so you can scuttle back into bed in no time.
It comes in single to super king sizes. The best news is, it's now a bargain too, as it has been reduced by 20% in John Lewis' sale.
Whether you're shopping for a single duvet costing you just £20, ta double at £24 or super king at £32, one thing's for sure - you're getting a good deal.
What the reviews say
The Synthetic Soft Touch Washable Duvet, 4.5 Tog has received plenty of attention from shoppers, and garnered over 300 five-star ratings. Here's what shoppers have to say:
"This is the second duvet of this type we have bought from John Lewis. It's beautifully soft and whilst we bought a summer weight of 4.5 tog, it keeps us snug and warm."
"An excellent buy. I am really pleased with it and would buy it again."
"4.5 tog just right for summer months. Feels light and fresh, a quick shake every morning and it plumps up beautifully."
"Perfect summer duvet, just the right weight, light enough to be cool but perfect when there is a hint of chill in the air - a plus point is lovely silky feel to the cover."
"Having purchased the winter weight version of this duvet, and found that excellent but too heavy for summer, I treated myself to the 4.5 tog summer weight version.. So soft, and comfortable, the best duvet ever, and washable too."
