Best topper ever but needs a cover
Super comfortable and great quality. It's so deep and snuggly to lay on. It has gotten rid of my back pain and makes breastfeeding in the middle of the night way more bearable. Only down side is there's no cover for it,just a big slab of foam which is hard to manouvre.

Excellent
Very pleased with my purchase. It was rather flat on arrival but after the leaving it for 24 hours it was full expanded. It fits my mattress perfectly and the quality is fab. It’s lovely and soft to sleep on. Excellent value for money.

Comfortable come time.
I bought this and followed instructions to leave it flat for a couple of days in a spacious room for it to settle.I then placed it on my bed and it was so uncomfortable,hard as a brick!! I put up with this,sadly for 2weeks, ready to return it, until I googled it, it said heat was needed to relax the foam, I did this with a plugin small heater at the side of my bed for the next week for an hour every evening before I went to bed,what a difference,so comfortable!Such a pity that the wholesalers do not tell you this.

Non slip, save your money on other toppers
An excellent topper! Bought several of those duvet type toppers in the past, the ones with the elastic side straps that hook onto the four corners….the ones that refuse to stay put…waste of time and money, all of them including well known makes. This foam topper is the “bees knees”. It stays put, is pure luxury on my mattress and have never slept so well. I’ve changed it from top to bottom after a couple of months just to even out in case of flatness but no sign of any change in depth, or comfort since day 1. Would buy again and recommend it.

Cracks
This mattress topper is really soft. I liked it but I’ve had it for 2 weeks and it’s starting to crack. I’m just sleeping on it and I have no idea why but there are half a dozen small cracks on the memory foam. Also, the topper doesn’t expand to fully fit a twin sized bed.

Like a cloud
Since I have this mattress topper I sleep like I am on a cloud! At the beginning it was uncomfortable to get use to, being so different than why I normally use: a hard orthopaedic mattress underneath for my scoliosis. I use to think a hard mattress offered better support for my back but I would always wake up in pain. Now with this I really have good sleeps and wake up feeling rested, with less pain, I cannot say my pins and needles are gone but they are not as disturbing as with a hard mattress. I would say this is the right combination: hard orthopaedic mattress below then this item for a perfect sleep

Replacement topper. Stinks.
Liked comfort. Disliked the fit (over size length), the colour difference which the photos fail to show accurately. Colour correction would be nice but I fear they’ve altered this on purpose. Dislike the fact it’s not covered as my previous topper was. And most of all. The chemical smell. I don’t mind these things usually but this thing. Make you turn your nose up every night. I aired the thing. I opened windows (December 2022 anyone) I had an air filter running full pelt when I went out (stripped the bed and hoped for the best). 12 days later. You can smell the topper as soon as you get into bed. As soon as you move the covers. Every time you turn. It’s horrible. I should have spent twice as much and gone with the previous brand. Not pleased. I’d return if I could/wasn’t a hassle. I expect this will have to be binned/given away soon. It’s a terrible smell.

Just bought our 2nd round of this mattress topper! The first one ripped a little after 3 years of usage! We love love love it!! We stay cool, got rid of back pain and it’s sooo comfy. If you read that it has a weird smell that’s called off gassing and you just need to leave it in an open room while it fluffs up. The odor goes away.

I love my extra firm mattress but lately I’ve started getting joint pain. Bought this memory foam topper and my joint pain is gone! Just had to trim the end of the mattress as it’s California King (my mattress is European King size which is 10cm shorter). Highly recommend this mattress topper!

Lo que esperaba por el precio. Me hubiera gustado mayor grosor/densidad.
