Sevenlife 100% latex mattress problem
EDIT, 15/03/2025:"bedroomstylereviews.com_ break-in-a-latex-mattress" shares some useful information, which should be found on Marcapiuma's website, or in a User Manual, instead of the claim "non-deformable" mattress. Though there's a very important point in the above mentioned article: "...you may notice slight dips or body impressions in the mattress which – unless the mattress is defective and needs repairing/replacing /under the warranty or sleep trial – should not exceed 0.5 inches in depth and should actually aid with making your mattress more comfortable."
The dips in our mattress are the double of that. I have read many reviews of this mattress and some of them claim, that the mattress is too firm, as a negative feature. Though, many says that it's pretty soft. I'd say that ours originally is definitely firm and got a lot softer where the body imprint can be found. If you are moving a lot during sleep, then you'll probably soften the majority of your mattress, my son is a calm sleeper, so he pressed his "bodyshape" in a small, restricted area, which is a pretty weird "feature" and I'm not convinced, that it's healthy in the long run, and not convinced that our mattress is not faulty. I'll try to break it in and update.
Original, 12/03/2025:
I’m trying to warn everybody to the drawback of the Sevenlife 100%(?) latex mattress. I do not recommend buying this type, unless you’ll be happy sleeping on a mattress which firmness quickly reducing where your body imprints will be and then stays like that for the next 15-20(?) years.
I’m giving 2 stars, because it’s a product review and not a company review, and Marcapiuma has done what they could to protect their business and maybe their other products would have suited me better. I wanted to leave a product review on eBay as well, but I just had to learn that reviews can only be left within 60 days from purchase, which doesn’t make too much sense on a product with a 10-year warranty.
I purchased a 90x200cm Sevenlife 20cm Latex mattress to my son (60kg) in July 2024 from eBay. Despite I’m in the UK, everything went well with the delivery.
My son started using the mattress in September 2024, so for 6 months now.
When I received it the first impressions were really good, the quality seemed perfect, it was “heavy” as a latex mattress should be, so it seemed a pretty good choice.
At the end of January 2025, when my wife changed the cover on his mattress, she asked me to come and check something on it, to my huge shock. The mattress had two dents, somewhere below my son’s hips and shoulders. They were not only visual, but can be felt by hand that it’s not on the same level and not the same firmness as the surroundings.
I contacted Marcapiuma via eBay, who were quick to answer, asking for some photographs and giving me some advice how to take those to help them identify the issue. I made photos and videos and sent them over. I had no answer for almost a week.
I sent them a message asking for an answer and set them a deadline to that. I quickly received the following:
“Good morning, the tolerance limits for material settling are defined by the UNI EN 10707 standard and subsequent amendments, which considers as compliant the loss in thickness of the finished mattresses of ≤1 cm +5% of the original length, width and height of the product, during their use.It is therefore simply a natural settling of the materials.Kind regards, Staff Marcapiuma”
Beforehand there was a name and that “personal touch” in the correspondence you should expect from a “a human-sized company in Italy” – as we can read from one of the Trustpilot reviews.
What is even worse than the indentations (which are at about the limit the standard set up – but, again, on a 6-month-old 100% Latex mattress!), is the change in the firmness of the material where the indentations are. I have never seen a mattress sagging that badly, and what’s more frightening, so quickly. Searching the net for mattress sagging, the LATEX mattresses always have the best sagging-proof capabilities for up to 10 years! I turned ours twice since I contacted Marcapiuma, and the indentations are there after some days of sleeping on it!! Again, a 60kg boy!
It's like sleeping on a pretty old, soft, foam mattress, where you stuck in a fixed position in a valley in the middle of it.
Marcapiuma might be right that this mattress complies with the above standard. The standard only sets up size tolerance and not firmness tolerance, which is here the real problem. I’m 49 and I wanted to buy a really good mattress to my son. I’ve used many mattresses before, but never seen any behaving like this. Maybe it’s up for the standards, but I would never buy this type again. It’s cheaper – it’s not cheap at all! - than any other Latex mattress on the market, but maybe that’s where the problem lies.
