I was unsure when i purchased the mattress for my teens bed as the price was so good. I read the reviews and took a chance. The mattress arrived quickly and was packaged well. It looks great and the quality appears to be good. It is so comfortable and fits perfectly. The mattress is firm and after lying on it and it warms from your body heat you can feel the memory foam gently adjusting to your body shape. Have only had for a few weeks but it all seems great. The instructions did not state how long to leave the mattress to unfold and puff up before use so gave it 24hrs and all seems fine. Would definitely buy again.

My son is fussy he’s not slept well for ages I got this mattress I was unsure because of the price being so low how the quality and comfort would be, but it has past the test! I am so pleased! Excellent quality! It popped right out into position and ready to go and he had a great nights sleep it is early days but so far so good, I would definitely recommend.

Well compact packaged and easy to move. Once opened it expands and takes a couple days or so to get full shape. When first opened it was very soft and I got a bit worried but give it time and it expands to natural shape and firmness. The first inch is medium firm but then the rest is very firm. Seems good quality, you have to decide if you’re comfortable with a firm mattress. I’ve always had a soft mattress, but to be honest I thought it would be a little softer but I suppose over the coming months it will sink and become so.

This product came last week and was well packed but slightly battered and left in garden not porch provided but it unpacked and inflated very well in less than 48 hrs and fitted bed great and is very firm but extremely comfortable and you don’t move about my last mattress was 30cm and this is 20 dept so a bit of height adjustment but I’m very happy with this I’ve had back problems with last mattress but don’t feel it with this one I probably would like my next mattress to be 25cm depth and a little less firm slightly softer but at moment I’m totally enjoying this mattress it’s great value for money and great quality so a great buy thanks

J’avoue avoir commandé ce matelas sans conviction aucune, ayant pourtant étudié quelles caractéristiques me correspondraient le mieux (poids de corps notamment). Le matelas a repris sa forme en moins de 24h. J’ai malgré tout respecté les 72h avant de l’utiliser et il est bluffant : sensation de dormir dans un nuage. Ni mou ni ferme, il est juste parfait. Maux de dos disparus. J’avais un matelas IKEA auparavant, et je regrette presque de ne pas avoir regardé Amazon à l’époque ! Cela fait 2 semaines que je l’utilise, je mettrai mon commentaire à jour si déception sur la durée. Mais vu le prix, il est quand même bluffant. Zéro odeur désagréable de surcroît, ce que je redoutais.

I am very satisfied with this mattress. It is not hard, but not too soft either. The sleep quality is great. What is very good is that it is springless, so it does not make any extra noise and does not prick the sides when you lie down. Plus, it is not expensive.
