great mattress for sleep

I'm happy with the overall quality of this mattress, especially considering the price. It feels well made, and the memory foam is comfortable without feeling too soft. I would describe the firmness as somewhere between medium and medium-firm, rather than truly firm. It has a good balance of support and cushioning, so it works well for everyday sleeping. If you prefer a very firm mattress, this may feel a little softer than expected.

Excellent buy, extremely confortable.

My last Zinus lasted 8 years so it was time for a new mattress. I have a 3” latex topper so I didn't need anything but a basic medium firm foam mattress. It's placed on a slatted wooden platform bed frame. Shipping was very fast. This mattress comes well packed, tightly rolled and doesn't do anything scary when you open it. It's supposed to open to 12” thick I let it sit for about 48 hours and it opened to about 10-11 inches. No funny smells fumes etc. I would say it is medium in firmness and the memory foam surface softens the feel but you don't sink down. With the 3” latex topper it's the most comfortable bed I can remember. Great side sleeping support and when you sit on the edge it doesn't sink down much. No movement transfer from partner. Be aware if you get the Angi mattress removal it does not include removing the cardboard shipping box the new mattress comes in which is ridiculous and I cancelled the service for that reason.
