We’ve had this for 5 months. It has made such a difference. Our mattress really sucks and I kept waking up with back pain. This was incredible the first few weeks. It’s obviously not as plush anymore but our bed is still way more comfortable. It adds thickness to your mattress so it’s a little hard to wrap the sheets around it but it’s worth it. Haven’t woken up with lower back soreness in months! I’d buy one event year if I had to.
