Littens 4" (100mm) Extra Deep King Bed Size Visco Memory Foam Mattress Topper Profile, Egg Shell Crate Box, Orthopaedic, Support, Plain Relief (5ft, 152cm x 200cm)

It arrived very quick. And took all day to expand. And it had a very strong chemical smell. But we opened the bedroom window, and closed the door. So it didn't bother us for the rest of the day. In the evening once you covered it with sheets, the smell was hardly noticeable. And for the first time in years, I can sleep comfortably in bed again. I will recommend it for heavy people, or someone with bed sores, or back ache.

I love this topper with being so comfortable and warm--ideal for the arthritus!

Best nights sleep ever, so glad I went for the thicker one

Needed something for my back this is brilliant abit smelly chemical smelly but eventually it goes

Superb. Like OMG I'm not tired today. I know normally I toss and turn all night and get dead arm etc. Last night I went to sleep and only woke up when it was light. My wife has an injury from when she was younger which and makes sleeping painful for her. Which is what prompted me to read lots of reviews and pick this one. (Kingsize 100mm with the bumps). and she texted me from bed this morning "Thank you for buying this heaven mattress ❤️❤️😘😘😘".Left it for about 4 hours before setting up for the night, no bad smells (which is why I bought this one). There is a mild new smell, but it reminds me of almond cakes so nothing unpleasant.I think probably the best thing I ever bought off Amazon. Been working from home for a year and finally dont feel tired. I'll update if it doesn't last well and downgrade, bought April 2021 so if you are reading this in a few years time then its lasted well. Ps bumps go up to provide air pockets to stop overheating and more flex for comfort. I'll end by saying, it's also stops your knees aching if you are "excercising" ;)

This is a very thick block of sponge which has a terrible odour. It took days do air. Sagging already. Just so overpriced and not worth the money.

Hoped for relief from pain and was delighted with results

I love it , very comfortable and soft which was really important to me . I highly recommend
