If you’re struggling to sleep in the July heatwave, this £50 IKEA duvet is perfect for sweaty nights – it’s ultra lightweight and cool to the touch
It's perfect if you find an empty bed uncomfortable
Considering we’re in the midst of a second heatwave, and it’s only the start of July, it’s about time you invested in a lightweight summer duvet (if you haven’t done so already). If you’re a hot sleeper who hates not having a cover, IKEA’s £50 BLÅNEPETA duvet has you covered - at just 2.5 tog, it’s ideal for sweaty nights.
If you’re too hot to sleep, there are plenty of duvet alternatives we recommend to ensure you get your beauty sleep on sticky, humid nights. When the best duvets feel too hot, opting for bedding such as a flat cotton sheet or using a Dohar is a far cooler option.
The IKEA BLÅNEPETA duvet is one of the lowest togs you can buy and promises to help keep you cool this summer. Here’s how it shapes up.
IKEA states this duvet is perfect for ‘warm nights when you want to cosy up but remain cool.’ It uses blue lyocell material, which it states feels cool to the touch and wicks away moisture, keeping your sleep environment dry and dry.
‘IKEA's BLÅNEPETA duvet looks like a good choice for hot weather. Lyocell is smooth, silky, and cool to the touch, and the 2.5 tog rating is one of the lowest warmth levels you can get. Duvet tog does go down to just 1 tog, but many of us like something a little weightier to sleep under, even when the temperatures are hot,’ adds Amy Lockwood, Ideal Home’s sleep editor.
However, due to its synthetic material, some experts say it won’t offer the same cooling experience as a lightweight natural fibre or bamboo duvet.
‘2.5 tog is a sensible weight for summer and will suit most people who find an empty bed uncomfortable. The BLÅNEPETA uses a lyocell filling, which is a form of recycled polyester, and that is where I would flag a consideration,’ says Richard Lord, founder of bedding company Lost Loom.

‘Synthetic fillings, however lightweight, do not breathe in the same way natural fibres do. They tend to trap moisture against the body rather than wicking it away, which means you can feel warm and clammy even if the tog rating itself is low.’
Instead, Richard recommends an option for a lightweight duvet filled with natural fibres or bamboo. For example, John Lewis' 2.5 tog cotton duvet (£85 for a double). However, IKEA’s BLÅNEPETA is a great choice for smaller budgets, and the reviews do highlight its suitability for summer nights.
‘It's not magical, but it is very good. I love having a coverlet that's got more weight than a sheet but is still light. I've seen reviews that complain about the colour showing through duvet covers, but honestly, why use a duvet cover? I'd love it if it came in more colours, but the blue is really pretty. As a perimenopausal woman who wants to keep the bed as cool as possible, this is what I'm going to be sleeping with all summer,’ said one reviewer.
‘After going through several down comforters, I finally found my perfect weight and warmth level for S. Florida. And love the price,’ said another.
Alternatively, I’ve found a few more affordable options you can shop online.
Don’t let the heat necessarily disrupt your sleep. As summers are set to heat up in the coming years, it’s a good idea to invest in a lightweight summer duvet now.
