Comfortable nights.
Hi, after 25 years sleeping on 2 Tempur mattresses the switch to an Ergoflex was seamless. My wife and I are very happy with our purchase and continue to sleep very well on this new Ergoflex mattress.

Really comfortable bed
We are very pleased with our Ergoflex mattress. It is really comfortable. Warm and deep firm mattress. As a light sleeper I am no longer disturbed as I do not feel my partner moving in the night. Great ordering experience and delivery.

A Great Replacement to Earlier Ergoflex
A replacement to a much earlier Ergoflex that lasted well past the original 10 year guide life that was great for all that time. The new one is still a great product, super comfy, excellent nights sleep and continue’s the product line superbly well. No complaints very glad to have made another purchase of this Mattress type and definitely well recommended.

Very worth it!
Had the mattress for about a month now and it is indeed much better than dunlopillo which I had before. It moulds indeed on your back and my back aches have now reduced. I bought two single mattresses for two single divan beds next to eachother as my husband is suffering from restless leg syndrome and would keep me awake. This solution was a godsend because these mattresses do not make a wave when the other person is moving. Also the price was very good compared to other much lower quality mattresses. All worth it indeed.

I was sceptical to change to a memory foam mattress, it was a friend who recommended ergoflex, said he went to a bed and breakfast for the weekend and had the gest nights sleep, he asked the owner what mattress it was as it felt like sleeping on a cloud , he bought one when he got home , i read the reviews with very little negatives. So bought a super king one , five years later I can honestly say its the best mattress I have ever slept on , I miss it lol when on holiday and look forward to bed time each night . Highly recommend this mattress.

Comfortable but not firm.
Comfortable but not firm.
This is the second ergoflex mattress I’ve purchased, this one was ann upgraded one, it claims to be medium to firm but in my opinion it it soft to medium. It’s not as supportive for my back as I would have liked. I hope it doesn’t get any softer.

Fantastic service,quality of product and worth every penny. This purchase was for a replacement Ergoflex to replace my 14 year old Ergoflex mattress which has given me endless good nights sleep. You definately get what you pay for. Absolute comfort. Now I am 81 years of age the support for my entire body is perfect.
I highly recommended this company .

Highly recommended
We have replaced an existing ergo flex mattress so are already converts. The service was great. Although the item I wanted was not in stock when i ordered I was notified when it was available and it was delivered quickly after that.
The mattress is extremely comfortable and s I suffer from tendinitis in my hips it allows me to sleep comfortably.
Highly recommended.

Fantastic Customer Service
I bought a mattress and I absolutely love it so far. Easy to unpack and very comfortable. However I am leaving a review due to the brilliant customer service. I decided to order the mattress protector but unfortunately DPD kept failing to bring the package to the door. Customer service were extremely helpful in re-arranging the delivery with fast responses and finally getting the item delivered on the 4th attempt. Top customer service. Thank you!
