### ⭐⭐⭐⭐⭐ Positive Mattress Review
*by S***D on 27 May 2025*

I recently purchased this mattress and have been extremely impressed with its quality and comfort. I am writing this review after using mattress for more than 100 days now. From the very first night, I noticed a significant improvement in my sleep. The mattress provides excellent support, especially for my back and shoulders, while still feeling soft and cozy. I appreciate how it contours to my body without sinking too much, which helps reduce pressure points.Another great feature is its motion isolation-my partner and I can move around without disturbing each other. The materials feel premium, and there's minimal off-gassing, so it was ready to use almost immediately. I also love that it stays cool throughout the night, which is perfect for someone who tends to overheat.Overall, I highly recommend this mattress to anyone looking for a great balance of comfort and support. It's made a noticeable difference in my sleep quality, and I wake up feeling refreshed every morning.

### ⭐⭐⭐⭐ Ultima Memory Foam
*by L***N on 30 September 2024*

Bought Ultima Memory Foam 2 months ago, King Size, the Mattress is very nice. Have visited the experience center in Anna Nagar, Chennai, and the touch and feel was very good, and the top layer retained the chillness compared to other mattresses. Very comfortable for any sleeping position. Not recommended for sitting for long hours, say more than one hour or so, since the top layer is so soft causes some hip pain. But for 15 to 30 minutes, it won't be a problem.It is a good choice to have this mattress for a comfortable sleep.
