Harwich GB
Sturdy but uncomfortable
You can feel the toggles (where it forms the dimpled gatherings) on it. They dig in, especially laying on your side. It should be adequate for my weight (heavy) but it is not.
Tried cutting off 2 of the toggles but still uncomfortable. Have had to order a 3" mattress topper for it as unable to return after trying to make it comfortable!

Hi Carol,

Thank you so much for taking the time to leave your review, it is very much appreciated.

Please do not cut the tuft buttons off on your mattress; these tufts are what hold the fillings together, this will also void any guarantee that comes with your product.

The mattress will feel firmer initially and the loft will be greater as there has been no weight distributed across the mattress surface, please ensure you follow the care guide to ensure even settlement, the topper will be a great addition whilst transitioning to your new mattress.

Kindest regards,

Merseyside GB Single mattress
Mattress looked and felt good on arrival
The company I ordered from I would give 10/10 I can fault them or their service
After a few weeks mattress has started to go loose and certainly won’t last long ..... I’m already looking for a replacement...... disappointing considering the price
