Not fit for purpose.

Originally posted on Silentnight

This mattress is advertised as ‘soft’ but it is most definitely not. Hidden in the description it is described as ‘medium soft’. the which contradicts the other description. It does not keep me cooler either. Soft beds are for lightweight side sleepers and this bed has failed completely. I bitterly regret this purchase and there is no point in and exchange as this is Silentnight’s only soft mattress.

Amazing mattress - Comfortable nights sleep at las

Originally posted on Silentnight

[This review was collected as part of a promotion.] Silentnight Memory Cool 3000 Box Top Mattress Firstly, I do not typically sleep well and never really have. But.. I have had some really comfortable, long nights of sleep since getting our new mattress. It arrived and was packaged really well. Although it took a while to unpack, it was well protected. Exactly what you'd hope for when you're ordering an expensive item. The mattress itself is made with memory cool, which I Silentnights cooler, sink-in memory foam. It's made with graphite infused particles within the foam, allowing heat to dissipate. The mattress is thick and as soon as you sit or lay on it, you melt into it. I would highly recommend, as myself and my partner now look forward to a comfortable night sleep every night. Which in our opinion, makes this priceless!

Supportive and best nights sleep ever

Originally posted on Silentnight

[This review was collected as part of a promotion.] WOOOOW what a thick mattress. With the 75%off what great value. I've had the best nights sleep I've had in such a long long time. I've used it for 3 nights and can say it's for sure supportive, I was worried at first because they only did "soft" however it's not fall into the mattress soft it holds your body weight and let's you turn without disturbing your partner.

Big, Comfortable and Cool

Originally posted on Silentnight

[This review was collected as part of a promotion.] First thing you’ll notice is that this mattress is huge! At 37cm deep, it’s significantly taller than a standard mattress. Once it’s on the bed, you’re sitting quite high up, which takes a little getting used to. Be prepared to buy extra deep fitted sheets and a protector to match the size. It’s rated as medium/soft and I’d say that’s spot on. The plush box top gives a soft, cushioned feel as you lie down, but there’s a reassuring level of support underneath that stops you from sinking too far. It took a couple of nights to fully adjust, but overall it feels very comfortable and well-balanced. One thing that really stood out is the cooling effect. It seems to work well. Despite some unusually warm nights here in the UK, we haven’t experienced any overheating or night sweats, which is a huge bonus. Motion isolation is impressive too. You barely notice when someone else moves or gets out of bed, which has definitely helped with uninterrupted sleep. No noticeable aches or pressure points so far and it’s very easy to get comfortable. It feels especially good for back and side sleepers. Still testing how it performs for stomach sleeping but early signs are encouraging. Overall we’re really pleased. It’s a high-quality, luxurious-feeling mattress that offers comfort, support and temperature control all in one. A great upgrade.

Super sleep incoming

Originally posted on Silentnight

[This review was collected as part of a promotion.] I was so excited when this mattress was delivered and I wasn’t left disappointed. It’s an absolute giant of a mattress, wasn’t sure it would go up the stairs. Thank goodness it has, it’s been a serious life changer. Very supportive and soothing on sore muscles added to the fact I now sleep like a baby. When buying this you definitely need extra deep fitted sheets.

Super comfortable

Originally posted on Silentnight

[This review was collected as part of a promotion.] I absolutely love this slight night 3000 cool memory foam mattress. It's so thick and super comfortable. I got this one for my son, but I definitely should have got one for myself. My son is over the moon with it. He's definitely having a better night's sleep with this mattress, which is very breathable and shapes to your body shape, helping you have a better night's sleep. 1000% recommend this mattress.

Like sleeping on a cloud

Originally posted on Silentnight

[This review was collected as part of a promotion.] Wonderfully comfortable, I struggle with overheating in bed but can instantly tell the difference since using this mattress. I’m finally Having Cooler & a more peaceful nights sleep, & haven’t woken up with the usual aches & pains. These are rather heavy & thick, but they don’t have to be turned over, & this deeper mattress is great if like me, you like your bed to be higher up. I would consider this to be one of the best mattresses on the market from what have seen & tried I’m Looking forward to many years of quality sleep Worth every penny Even the cats agree

Originally posted on Silentnight

[This review was collected as part of a promotion.] I got this mattress at a hugely discounted price & wow! What a mattress . It is so thick & super comfortable. My first nights sleep was absolutely incredible. It kept me very cool throughout the night & I felt very supported. I woke up feeling very refreshed which I haven’t felt for a long time due to having a cheap mattress. The depth is unreal to the point I need new fitted sheets as mine are not deep enough . Overall I would recommend this mattress to friends / family & any others who are thinking of purchasing an upgrade. It is well worth the money.

Excellent

Originally posted on Silentnight

[This review was collected as part of a promotion.] Once we finally managed to get up two flights of stairs (oh my god huge effort, it weights 55kg) and get it on our bed base, it was great. Very comfortable, lovely support, breathable. I’ve no idea how we are going to get it out of the bedroom though! One thing I will mention silent nights delivery company will not put the mattress in your room of choice if they need to bend the mattress. It’s against their ‘policy.’ So unless you’re lucky enough to have no corners to manoeuvre around, then you should be fine.
