DISAPPOINTING

I was looking for a topper to make my mattress more 'cosy' as it is quite firm. This does not seem to be 4" deep in the centre - despite leaving it to rise after the vacuum packing - and gives me no more cosiness than a thinner topper. It is well made and stays in place without moving so I have no complaints from that point of view. Maybe I was expecting too much.

Not as described

No, I don't recommend this

Doesn’t hold the thickness , flattens relatively quickly no real gain from purchase

Topper

Puffed up well after 48 hours but top, bottom and side panels are quite flat. There is no way you could return this as it comes vacuum packed and it would be like putting a quart into a pint pot!

Very comfortable, definitely enhances an aging mattress but I’ll have to remove it in warmer weather as it will be too warm for me.

I was having problems with sore hips. Thought would try this mattress topper to see if it would help. Glad I did, best nights sleep I’ve had for months. So soft and comfortable and my hips are so much better.

We have been sleeping on this for a few weeks now but to be honest although comfortable l had hopes it would feel softer & provide me with the sinking into marshmallow feel.

Like sleeping on a cloud of comfort

Yes, I recommend this

Love this topper, it is a good depth and has made a huge difference compared to the last one we had which was much thinner. We can no longer feel the buttons on the mattress! The quality is excellent and I can highly recommend. We gave it the suggested 48 hours to fully plump up.

Great topper purchase for a medium mattress as thought it may be a little firm and need a little softness boost.

Absolute rubbish. This topper is supposed to be 10cm thick but it came squashed. Had to work hard to return it & having had to pay for return postage, I still haven’t had my refund after 3 weeks. Never buy directly from this company

Really comfortable to start with

Yes, I recommend this

Initially it is so comfy but, does flatten very quickly - no problem to fluff it up again but weekly is a bit much when you have to strip bed each time
