All memory foam products will become softer as the temperature rises and firmer as the temperature decreases.

It goes without saying that you should always read your pillow's care label and follow the directions accordingly.And after an especially horrendous week of sniffing and sneezing, the last thing we wanted was a mattress topper which would worsen our symptoms, so we were slightly wary about this duck feather and down mattress. Before we delve into our review though, it’s important to note one thing – mattress toppers shouldn’t be confused with protectors. Full disclosure: we were sceptical when we read that this topper contained wool, simply because we don’t particularly associate wool with comfort – rather a general scratchiness which isn’t usually conducive to a great night’s sleep. This could be the bed accessory of your dreams, thanks to a box construction which ensured the evenly-distributed fibre filling stays put. Product Details: The pillow measures 60x40x6cm and features a memory foam core that takes 4-48 hours to recover its original shape.

They should spring back to the same height each time you use it, so you don’t need to fluff it up to keep it looking and feeling as comfortable as possible, but they do tend to be on the warmer side.This pillow is formulated to alleviate pressure on muscles while you sleep by supporting your neck and head correctly. It kept us wonderfully cool (the blurb credits this to climate control technology, but we suspect the heavy use of cotton had a role, too) and provided just the right amount of support. But we’re slightly ashamed to say our current mattress is well past its expiry date, and this testing process revealed that, while most toppers do a great job of cranking up the comfort, few were able to breathe new life into old mattresses (such as ours) as well as the Simba topper. It’s ridiculously comfortable – we’re restless sleepers and are especially sensitive to lumps and bumps, but sleeping on this topper felt like dozing off on a cloud (not that we’ve ever done that, to be clear, but we’re fairly sure the experience would be similar).
