Super King Ecosa Mattress

Recently purchased the Ecosa Superking mattress and am very happy with it so far. It’s the first foam mattress I have tried and it’s very comfortable. Keep up the great work Ecosa 👍🏻

Super King mattress

I am looking forward to go to bed every night. It seems that I didn't ned to adjust either. For now it is a very good experience !!!

Amazing

Over Christmas we finally took the plunge and bought an Ecosa mattress (super king). Both my husband and I have suffered from back & sleep issues, further impacted by a terrible mattress (only 3yo and very expensive mind you) owwhich sagged and didn’t provide adequate support. I’ll be honest that when the mattress arrived, and even with a topper the first couple of weeks felt very hard (be prepared). But as they say on their website, be patient and give your body time to settle. We are n sleeping so much better and my back is so much better!! Would highly recommend this mattress to anyone.

Fabulously surprised!

We’ve been using our Ecosa mattress for over a month now and have been fabulously surprised with just how great it is, after being very skeptical at first., We have the super king and the partner disturbance is minimal according to my hubby. I’m a bit of a tosser however I’ve found that I need to change positions much less (and some nights not at all) with this mattress. We’ve recommended the mattress to friends and they’ve just purchased one. Honestly, after having 12 months of drama with a sleepyhead mattress that had to be repaired and replaced numerous times, it’s wonderful to have a great mattress to sleep on. Definitely recommend!
