Sealy Walsh Hybrid (Thumbs up)

Purchased: 02-19-2026 First off, I had a 15 year old Tempurpedic Classic mattress that was causing back pain and needed to be replaced. I have a solid base (purchased with the Classic) which sits in a sleigh bed with slats. Sleep style: (combination) side and back. body style: 5'10"-235lbs The Walsh is more of a Medium Firm mattress; which is what I wanted. My first night sleep, my back pain was near gone. I did experience some fatigue in my shoulders but the trade off was well worth it. I believe that this would be solved by a foam topper of your choice. I also believe that the shoulder fatigue will go away as time goes on. This mattress has fantastic support. The edge support is great. It is comfortable and provides a great nights sleep. I had missed having a traditional spring mattress and this hybrid provides the best of both worlds. If this is what you are looking for; you won't be disappointed. If you are looking for plush and soft pillow top, then this is not it. Hope this helps.

Firmer but very comfortable

This is an excellent mattress. It is very firm when you first get it. I thought I accidentally got a firm mattress. It softened up after 2 weeks of use. Even though its on the firmer side - it hits all the pressure points. It feels great to sleep in. I actually ordered a second one for my sister. We had been plagued with back pain from 'soft' and 'in the box' mattresses.

Comfortable and Supportive!

⭐⭐⭐⭐⭐ I bought this mattress in January and loved it so much that I just bought another one for our guest room! It feels firm at first, but slowly contours to your body and is very comfortable. My old mattress was causing back pain, and this one has made a huge difference. Great mattress and definitely worth it!
