Silentnight Deep Sleep Mattress Topper King Size Bed - Soft Supportive Comfortable Durable Bed Topper with Easy Fit Elasticated Straps - Hypoallergenic and Machine Washable - King - 200x150cm

Great mattress topper for the price. We’ve put this on the bed in our guest room and already had complements on how comfy the bed now is. It’s super easy to put on the mattress with the elastic straps and a fitted sheet keeps it in place. Very happy with this!

Love this it's so comfortable. Very good qaulity and fits perfectly. Highly recommend and a great price too.

It's flatter once it's on, I don't think it's 10cm but it's soft enough and provides enough padding to make a comfortable bed. Good value for money. It benefits from re fluffing when you make the bed.

Wonderfully thick. Very comfortable. Best topper I have ever bought. Value for money.

Great quality. Really soft and comfortable.

No way is this 5cm,unless you double it by folding it in half,it's comfortable ish when folded in half and put on couch,rather pricy for what it is.I don't see it helping with an already sagging mattress at all,at least it's washable,haven't washed it yet though,came vacuum packed,it didn't expand much days after.I had passed the 30 day mark for returns Amazon chat wasn't helpful, went on citizens advice website which states that if you're within the 6 months window you're allowed a replacement if goods are not as described /faulty.Seller was polite and sent out a 2nd so I'll double up, they however sent it early when I said not to because of day sleeping but I got it in the end. Both (same model number) were under 5cm, so if you absolutely have your heart set on this brand get the thicker one and check the recent reviews which may indicate size if they're not the most highly rated. I think Evri delivered it but not 100% sure

Very thick and soft, perfect fit, very warm

Feels lovely without adding too much weight to the bunk bed mattresses which are quite thin. Only downside was I bought 2 and one arrived without the second elastic band to keep in place. I'm hoping it doesn't move too much but it's on now and I haven't got the energy to get replacement.

Topper perfetto come lo cercavo! Non troppo alto e imbottito ne sottile e vuoto. Per me la giusta morbidezza. Ultra confortevole e ben rifinito morbido al tatto...come entrare in una nuvola...consigliato!!!

The mattress topper grips the mattress with two large horizontal straps, instead of a diagonal strap for each corner. This means there is almost nothing to stop it from slipping, which it does.

Not thick enough the 10cm topper is barely a 5-6cm

Too thin, not worth the money, looks like cheap material.
