The mattress is the thickest and firmest mattress I’ve ever bought. I was looking for supper support and it seems this mattress is the best fit. I’ve only just received it so I’m giving 4 stars since I haven’t tested it out yet.

Silver BR 900 King Extra Firm Love my mattress. I have severe back issues and arthritis. Sleep and a good night's rest is a must. This mattress fits what I need perfectly. I will do another review in about 6 months. So far its great!

We noticed the bed is already conforming to our bodies. I am 150 pounds, husband 205 pounds. The bed still feels firm but with only 2weeks in with lumps it’s going back!

So comfy! As soon as I put the sheets, pillow, and comforter on, I fell asleep right away and slept like I never slept before. Really didn't even want to get out of bed. Almost called in to work, but looked forward to coming home.

I love this bed. I sleep on my side and back, and it's great for both. I previously bought a mattress that was way too firm, and my shoulder was soar when I woke up. Not on this bed. Would definitely recommend.

Very comfortable with the firmness we were looking for and the price we were happy with. The White Glove delivery duo were punctual, friendly and accomplished their task and gone in 20 minutes

I was looking for a very firm mattress and this bed is exactly as described. If you are ISO an extra firm, look no further because this one, will not disappoint. It is a very-well constructed mattress, as well as beautiful.

This is a good quality extra firm mattress, just like I wanted. Firm and stable, supports body. Does not sink or sag even when sitting. Great purchase and worth it.

This is a good mattress but not as “soft” or “plush” as the name might imply, nor as “giving” as the store mattress. I’m ok with it but would have expected something a bit different for the years of use I hope to get from it.

The first mattress was exchanged because it was defective and the second one sent was also defective. The mattress has a lump in the center and in the head and foot part it is sunken. The mattress did not meet what I needed
