Signature Design by Ashley King Size Limited Edition 11 inch Firm Hybrid Mattress with Lumbar Support Gel Memory Foam

The Signature Design by Ashley Limited Edition 11 Inch Plush Hybrid Mattress is a CertiPUR-US certified gel foam mattress. While it is plush, it may not be supportive enough for someone who weighs 300lbs. The mattress cannot be steam cleaned and it should be vacuumed for cleaning. The limited edition version has an extra layer of high-density base foam and 15-gauge pocketed coils, making it more expensive than the standard hybrid. Customer reviews are mixed. Some customers found the mattress very comfortable and supportive, while others complained about sagging and lack of support. The mattress is also reported to be quite hot to sleep on.
